Sometime in the later part of the third
millennium
a.t. a small group of nearbaseline
settlers along with several posthuman
overseers left the core of the emerging Utopia
Sphere
for a small system in the coreward
Middle
Volumes.
The single habitable planet in the system was scheduled to complete terraforming
a few decades ahead of the settlers' arrival. However on arrival at the
system
(at a now unknown date), the settlers were greeted by a disappointing
sight.
A flaw in the programming of the subsentient
terraforming ships had made them bombard the target world with far too
many icy
meteors and other volatiles than were necessary. A series of accidents
(possibly related to that flaw) had also caused the destruction of two
of the
seven terraforming ships. The result was a watery world with only about
7% as
inhabitable landmass. There was only a single large island-continent,
which
made up about 5% of the planet's surface. In effect, the world had been
"aquaformed" instead of terraformed. It wasn't a complete disaster as
the bio-replicators
had been successful in seeding the world with a fairly wide array of
living
species. Of course things weren't perfect as the original intent had
been to
create a land-based biosphere
rather than an ocean-based one. But the settlers didn't have enough amat
to go back or to move somewhere else, so they decide to stay and make
the most
of their new world.
In a few months the 3000-odd nearbaselines had all landed and were
putting
their advanced biotech
to
good use, improving on the basic lifeforms on the world to create more
variety.
Then suddenly their ship along with all the posthumans and most of
their other
equipment suddenly left. The settlers were effectively marooned with
nothing
much besides themselves, their newly constructed habitats and their
advanced
biotech.
The rest of the galaxy soon forgot the world and the marooned
colonists. It was
not until after the Version
War
in 4898
that an expedition from the Utopia Sphere entered the system. On
approach a
strange vessel greeted them and asked them to identify themselves. When
the
expedition had proved beyond doubt that they were from the Utopia
Sphere the
vessel allowed itself to be boarded. The members of the expedition
found, much
to their amazement, that the posthumans of the original (now forgotten)
expedition had coalesced and undergone a collective ascension
to SI:2
and had even integrated the surviving terraforming ships into their
original
ship. The new entity, calling emself the Wishful Watcher, instructed
the
expedition to move toward the watery world, but requested them not to
interfere
with anything they saw.
When they reached the world, they were surprised once more. From what
they had
heard from the entity, they had expected to find a crowded and busy
nearbaseline society squeezed onto the small island-continent. But they
found
that the continent was covered with pristine, undisturbed forest. In
fact, they
found no immediate signs of intelligent life at all. Their immediate
thought
was that the nearbaseline population had somehow died out during the
two
millennia between the expeditions. But a closer look revealed that
things were
far different.
The first unusual thing they saw was what looked like small circular
islands,
placed in almost perfect circles and heavily forested. But on closer
observations the "islands" turned out to be rings of huge tree-like
plants, with trunks stretching all the way down to the beds of the
shallow
oceans. Eventually they found out many more such biological marvels,
though the
trees were the most common. Finally they solved the mystery of the lost
colonists.
The colonists had abandoned most of the tiny continent in favour of the
much
larger and open ocean and in order to do so, they had become amphibians.
Consequently they had built themselves a stable amphibious and
biotech-based
civilization. Marooned without sufficient technology to start a typical
industrialized society, the colonists had formed a predominantly
agricultural
and piscicultural society instead. In accordance with the Wishful
Watcher's
request the expedition observed, but did not interfere. As they
pondered their
next step, the Wishful Watcher suddenly reappeared and offered them
information
on what had happened in the last two millennia.
Soon after reaching the system, the posthumans realized that the lack
of
habitable land would lead to one of two possible conclusions. Either
the
nearbaseline colonists would multiply and expand until there was no
longer
space for comfortable habitation, resulting in conflict, or they would
freeze
themselves into a rigid, technologically and culturally stagnant
society which
would ultimately creep to a slow death. Foreseeing inevitable disaster,
the
posthumans had taken measures that would force the colonists to take a
completely different path to survive. They had made sure that the
colonists
were all adapting to life on the new world, and were fairly comfortable
and
happy. At the same time, they also made sure that the colonists had
very little
technology besides their advanced biotech. That being done, the
posthumans had
left the colonists after memetically
ensuring that after a few months of turmoil, the colonists would again
continue
their work and embark on the new plan set up for them.
For a few decades they had watched from afar, always ready to return if
need
be. But once they saw the ecopoesis
of the colonists get underway in earnest, they left for the outer
system. There
they gathered the remaining dormant terraforming ships and ascended to
SI:2,
becoming the Wishful Watcher. Though the arrival of outsiders into the
system
had never been considered really important by the posthumans
themselves, the
Watcher said that E
would no longer interfere in the development of the amphibians, but
would stay
in the system until they were properly introduced to the rest of the
galaxy. Seraphim
from the Utopia Sphere arrived soon after that and began the careful
process of
adjusting the memeticity
of the new clade
(which
soon began calling themselves the Amphisapiens) so that they could join
the
rest of the galaxy.
In 5347
a body representing the various Amphisapiens habitats of their world,
christened Shaati Jol (Peaceful Waters), formally decided to join the
Utopia
Sphere. With this event, the Wishful Watcher ended Eir
two-thousand-year vigil
and returned to the Utopia Sphere. There E was rewarded for Eir
"efforts
to preserve life and devotion to a worthy cause". E was upgraded to SI:3
and given the freedom to explore the galaxy. E is currently somewhere
in the Zoeific
Biopolity.
The Amphisapiens gradually changed
themselves from a standard nearbaseline genotype
to an amphibious rianth/neogen
genotype, with features adapted from a number of different species.
Although
the exact method and steps used for the change has been mostly
forgotten it is
known that the changes took place over a number of generations, each
one coming
closer to the goal of a complete amphibian genotype.
The most important adaptation was of course creating respiration
systems for
underwater use. The standard Amphisapien design still keeps the lungs
as the
main respiratory organ, but enhances their efficiency. The Amphisapiens
can
hold their breath for up to an hour and extract almost 95% of the
oxygen available.
Special filter membranes at the entrance to the bronchi allow them to
increase
the percentage of oxygen in their lungs per breath. After breathing in
normally, this filter closes off the entranceway and their diaphragm
pressurises the air inside to force the nitrogen out through it. Almost
40% of
the air left behind is oxygen, which is double the atmospheric ratio.
Their
diaphragm is also used to force out the spent air after a dive allowing
the
lungs to be refilled with 90% fresh air in one breath. They also
increased the
amount of haemoglobin in the blood as well as creating a number of
complementary macromolecules that allows them to carry a larger amount
of
oxygen in the blood plasma itself, and their muscles contain high
concentrations of the oxygen-binding protein myoglobin. However this on
its own
is not entirely enough to fulfill their oxygen requirements. They also
have a
pair of gill-like structures on either side of their neck, which allow
them to
draw some amount of oxygen directly from the water flowing out of them.
This
water is taken in through the mouth but prevented from entering the
lungs by
the same filter at the entrance to the bronchi. Most of their body
surface was
at one time covered by a sub-dermal membrane which allowed a small
amount of
oxygen to pass directly from the water into the blood-stream but one of
the
later enhancements replaced the sub-dermal membrane with a set of
crosswise
flaps (generally five but six in some sub-clades) of skin covering the
shoulders and about a quarter of the back. The underside of these flaps
is
thick in ridges of membrane. This membrane is similar to the sub-dermal
membrane but is more effective while being more protected. While
swimming, the
action of water helps to separate the flaps and ridges and increase the
surface
area for direct absorption of oxygen. The climate of their homeworld is
warm so
heat loss is minimal.
Being amphibious, the Amphisapiens spend a large part of their time
swimming,
but can also stay on land for long periods. Amphisapien feet and toes
are quite
long and the feet are webbed. The structure of the ankle and foot is
also
modified. This modification allows the Amphisapiens foot to bend down
to form a
streamlined straight line with the rest of leg. Adult Amphisapiens can
'lock'
their feet into this position for long periods of time. Hair is almost
completely absent from the whole body and a layer of streamlining fat
smoothes
the surface.
Another important change was in the digestive system. The original
colonists were
creating an ecosystem
from scratch and they soon realized that they could create whatever
plants and
animals they liked, and could design them to provide nutrients in an
easily
usable form. Thus they could easily simplify their digestive systems
and over a
number of generations they did so, fine-tuning it so that they could
better
live off the ecology they were creating. They also created several
species of
symbiotic bacteria, which live in their digestive tracts and are
capable of
breaking down certain foods. The result was a much smaller, compact and
efficient digestive system. This is turn allowed them to increase the
size of
their lungs and also to create a muscular pouch along their belly. The
Amphisapiens place stones and other heavy items in this pouch to
counter-act
the buoyancy of their enlarged lungs. This allows the Amphisapiens to
be
neutrally buoyant (they can stay afloat while at rest at almost any
depth as
long as it is not too extreme) but also gives them the ability to drop
their
ballast and ascend quickly in an emergency. Their genitals are also
normally
retracted into the body and covered by this muscular pouch. Amphisapien
metabolism has also been greatly modified. It is somewhat slower than a
human
baseline's, which increases the time they can spend underwater, but it
is still
more efficient at processing certain compounds that are abundant in
their environment
while it is less capable of handling other substances. On the whole, it
can be
said that the Amphisapien metabolism has been carefully adapted to the
ecology
they created for themselves.
A common problem faced by many land-based lifeforms, when adapted for
aquatic
life is the problem of communication. Sound based communication while
very
effective for an air environment can be difficult under water, mainly
because
the vocal system in most Terragen life forms is directly and intimately
linked
to the respiratory system, making it almost impossible to speak while
holding
one's breath. A common solution is to move away from sound-based
communication
altogether and use light (similar to the Europans).
The Amphisapiens chose the latter, however they still retain fully
functional
vocal chords and can talk like normal baselines out of the water. Some
of the
few existing records show that an ultrasonic adaptation (using a
completely
different organ set to generate the sound) was in fact tried out, but
later
cancelled, probably because the Amphisapiens found it difficult to cope
with
the 'noise' produced by the echo of the ultrasonic sound, especially in
small
areas underwater. Ultimately the Amphisapiens chose a method of
communication
based on signalling using chromatophores. Large chromatophore clusters
were
placed on the chest and back region and smaller clusters on the arms
while the
lower limbs are almost entirely devoid of chromatophores.
Some of the most drastic changes are
to be found in the reproductive
systems and lifecycles adopted by the Amphisapiens. For most of their
history,
before being discovered, the Amphisapiens were playing a delicate
population
balancing game. On the one hand, they had to keep their population low
enough
as not to damage the fragile new ecosystem they were developing and at
the same
time, they had to grow fast enough to extend and maintain the ecology.
They
chose to make themselves long-lived, living for well over 400 years
without
medical assistance. At the same time they divided their lifecycle into
a number
of biologically based phases. Amphisapien children are all born out of
the
water, generally at above-water projections of their underwater cities
(see
below). Their gills and oxygen separating membranes are undeveloped and
their
lung volume is too small to hold air for a large amount of time. Their
haemoglobin levels are close to a baseline's and the complementary
macromolecules are produced in very small amounts. Like baseline babies
they
have little control over their movements, or their chromatophores. Over
a
childhood phase of about 13 to 15 years they develop their amphibious
organs.
At the end of this period they are fully capable of an amphibious life,
but are
still sexually immature. Up to this point, the children are completely
sexless
and have no sex organs in their bodies. Over a period of about 20 years
of an
adolescence phase, the juvenile Amphisapien develops sex organs and
sexual
characteristics. Extensive neural development also takes place at this
time,
especially in the areas responsible for perception, communication and
movement
(adaptations for the completely 3 dimensional environment of the seas).
At the
end of this, the Amphisapien is an adult capable of reproduction.
While chromosomes determine the sex of the individual at birth they
have the
biotechnology to change their sex easily. An Amphisapien is capable of
reproduction for about 250 years and during this time may change sex a
maximum
of 3 times (after which their bodies become 'resistant' to the sex
change biochemicals).
Sex change is a slow process as it involves change in the sexual organs
as well
as the brain and related psychology and can take a few months for a
complete
change. Though individuals can initiate and complete the change
entirely on
their own, by exposing themselves to the proper custom made
biochemicals, the
process is often monitored and guided by other Amphisapiens who have
been
specially trained for such purposes. At the end of this 250-year period
the
individual undergoes another transformation over a period of a few
years where
the sexual organs and hormones are lost entirely. The individual
becomes completely
asexual
and the brain areas previously devoted to emotional activity become
restructured to devote more neurons to more logic intensive thoughts.
The
result is a being that is biologically suited to be a manager, planner
and
leader. The individual remains in this phase, known as the 'elderhood'
for the
remaining period of jer life.
The Amphisapiens used not only genetics and biochemistry to alter
themselves,
but also used powerful bionano
and neogenics. Much of the development of an individual during the
various
phases, especially during large-scale restructuring, is done using
bionano and
a species of symbiotic neogen worms capable of analyzing an
individual's
genetic make-up and creating a fresh stock of stem cells, which are
then used
to create new organs. These worms also synthesize the biochemicals used
to
initiate and guide sex changes. The hormones responsible for the phase
changes
are made by the modified endocrine glands of the individuals
themselves. These
hormones trigger the activity of the bionano and the worms to perform
the
required tasks.
Amphisapien society is a
pseudo-nomadic one, and is influenced by their
lifecycle. The basic unit of society is not a family or clan based on
biological relations, but rather a 'siblinghood' based on age and
generation. A
siblinghood consists of about 500 to 700 individuals all of whose ages
are
within about 3 to 4 years of each other. These siblinghoods are
nomadic. But
there are permanent cities of no more than 200,000 individuals and each
city is
generally centred about a growing or developing ecology. Each city has
projections above water, which provide space for the birth of
Amphisapien
children, and is surrounded by a local ecosystem, created, or at least
maintained by the Amphisapiens. All births take place at cities, but if
there
is a large enough natural landmass nearby, it is also used as a
nursery. The
parents of a siblinghood generally all belong to a single siblinghood
themselves. Once their children are born at a city, they remain at the
city for
about 30 years, until the children near the end of their adolescence.
At that
point the parent siblinghood departs leaving the children at the city
in the
care of each other and the older permanent city residents.
Once most of the children have reached adulthood, they form their own
siblinghood and leave the city on the first of their own nomadic
journeys. It
is not unusual for these journeys to last for a few years. During this
time the
members of the siblinghood form strong bonds with each other, and males
and
females often pair into couples. Of course, not all members pair up,
especially
if there is a gender imbalance. After a few years of nomadic wondering
and
exploring, the siblinghood seeks out another city. Here they settle
down for a
few decades and help to improve and maintain the local ecology before
setting
off on another journey. When the siblinghood has reached the second or
third
city in this way, the members of the siblinghood generally decide to
have their
own children. Like their parents before them, they give birth to their
children
at the city's above-water areas and wait for about 30 years before
setting off
again. It is also at these cities that Amphisapiens may change sex,
guided by
the older, permanent residents of the city. The Amphisapiens will spend
all the
250 years of their adult life in this semi-nomadic way, travelling from
city to
city, helping out where they can, and gaining a varied experience. They
will
generally have children two to three times throughout this period. As
elderhood
sets in, the siblinghood will generally choose a final city to settle
in, or
may even decide to start their own city. Once they reach their new
city, they
will settle there and devote the rest of their lives to managing and
developing
the city and its local ecology.
Both the cities and the nomadic journeys play an important part in the
life of
an Amphisapien. It is at the cities that they receive education and
training in
various fields, related to biotechnology and ecosystem management. By
working
and helping out at the cities, the Amphisapiens can earn their stay and
also
various rewards, mostly in the form of resources, and biotech, which
they can
carry with them in their journeys. The cities also provide a meeting
place for
various siblinghoods and facilitate the exchange of information as well
as
stories about their journeys. It is also at the cities that
siblinghoods of
about the same age may join together to form larger siblinghoods, or
simply
exchange members.
However, to truly understand Amphisapien society one must look at the
Amphisapiens during their nomadic migrations. The migrations are the
periods
when the individual amphisapien develops his relations with his
siblings and
also explores his own nature. These long journeys often result in
enduring
relations between individual members, which last for a lifetime. As
with many
societies in the Terragen
Sphere,
where the members are long-lived, the Amphisapiens have no marriage
system.
Parenthood is more important. Two individuals having a relationship
with each
other may decide to have a child together. If both are of the same sex,
one of
them simply changes sex (this is easily achieved as both sex change and
childbirth take place at cities). Once the child has reached the end of
adolescence, they may decide to continue with their relationship, or to
separate. The process of forming and breaking relationships takes place
almost
exclusively during the journeys. There is little change while the
siblinghood
is at a city. Group relations are not uncommon, though parenting rights
sometime
become confusing, and sorting them out is generally left to the
individuals in
the relationships.
Amphisapien society is based on sharing, rather than on individual
possession
and trade. Amphisapiens have few personal possessions and little
attachment to
them. Most of them work for work's sake and care little for what
rewards they
get. They are dedicated to the development and improvement of their
local
ecosystem, and tend to view themselves as 'gardeners,'
working to sustain and improve their 'gardens' without the intention of
actively exploiting their creations. Often they will add elements to
their
ecosystem, simply for the fun of it, without caring if it is really
necessary.
They do however consider it wise to 'test the waters' with
non-reproducing
samples of these additions to see how they interact with the greater
whole.
The Amphisapien culture does not have
an indigenous religion but many
Amphisapien view their journeys to be spiritual experiences, as opposed
to the
material experiences of the cities, and after being reintroduced to the
galaxy
they have adapted a mix of Caretaker
ethos and Bioism.
As
they spread throughout the Utopia Sphere, and later the Zoeific
Biopolity, they
often formed 'cults' devoted to the local God. Most of these cults view
themselves as 'children' or 'disciples' of that local god, performing
the same
role for their ecosystems that their God performs for them.
The native Amphisapien spoken language is similar to the language of
the Utopia
Sphere, though Amphisapiens in other parts of Terragen space generally
adopt
the local language. However, their chromatophore-based language appears
to be
the same throughout the clade. Amphisapiens claim that they do not
"understand" the various colour patterns that they use to
communicate, but rather, they "feel" them in much the same way that a
baseline would feel emotions. There is some evidence that the
Amphisapiens
included some empath
genes, and the brain areas responsible for visual perception are quite
different from that of most other rianth species. Thus their visual
language is
more of a genetic trait than it is a cultural one.
Technology
Amphisapien technology is exclusively
biotech. Even their buildings and
vehicles are biological structures and they create neogen plants and
animals
with the same frequency that other societies would create new machines
or new
software. Like many other biocentric cultures, the local ecosystem
forms a
vital part of their technological infrastructure.
Amphisapiens live inside in huge plants, both on land and in the water.
The
"circular islands" that the Utopia Sphere expedition saw were
actually plants of this type. Amphisapiens prefer shallow seas to
deeper oceans
and their cities
are
usually in areas where the seabed is not too deep down. The cities
generally
consist of a circle of large trees, which reach from the water surface
to the
seabed. The tree trunks can be up to 200 metres in diameter and have
large,
interconnected hollow spaces inside. The hollow spaces, which vary in
size,
provide living space and space for other social activities. Some of
these are
air-filled, while others are water-filled. The actual structure of the
trees is
composed of dense plant fibres, as well as some bio-diamondoid
analog based support structures, which together provide structural
strength.
The trees also contain channels for transport of air and water, as well
as
communication networks made of a form of biological optical fibre.
There are
also special channels for the transport of nutrients and energy-rich
chemicals
used by the various biological machines, as well as channels for
removal of the
wastes they produce.
The outsides of the trees have large leaf-like structures, some of
which are
flat and serve as platforms and others that are closed spheres or
similar
shapes. A tree will have a roughly equal number of each. The flat
leaves are
more often above the water. Most of the closed leafs are underwater and
serve
as entry and exit points, as well as temporary storage locations. They
also act
as vehicle parking areas and airlocks, though the vehicles are mostly
aquatic animals.
Both types of leaves provide surfaces for exchange of gases.
The trees also throw out branches,
generally directed towards adjacent trees
and towards the centre of the circle. These branches are often hollow
and the
Amphisapiens guide the growth of the branches so that branches from
different
trees grow toward each other. When the tips of these branches come
close to
each other the Amphisapiens use a special neogen creeper/fungus to eat
away the
tips and join the branches, forming tunnels between the trees. In
developed
cities it is possible to go all around the circle without ever coming
into
contact with water from the outside. But the centre of the circle is
the most
interesting. Here dozens of branches from all the trees come together
at various
depths. More special symbiotic plants join the multiple branches, but
here they
don't form tunnels. Rather the joining of the various branches at
multiple
depths forms a huge cage, holding a multilevel, open-water metropolis,
where
Amphisapiens can easily swim from one level to the next. Considering
that most
cities have ten to a dozen trees and that there is over a kilometre of
separation between the trees, the metropolis can be a vast area (add to
this
the fact that there are often several levels). The exact use of this
area
varies from city to city, though in general it is used for large-scale
social
activities like markets and universities and often for hosting meetings
of the
City Council.
The tops of the trees reach above the water and there they branch out
into huge
branch and leaf systems, spreading over a roughly circular area about
500
meters in diameter and often extending over 70 meters in height. This
canopy
serves a dual purpose: firstly it provides much of the photosynthetic
needs of the tree as well as contributing to gaseous exchange, which
maintains
a proper oxygen level inside the tree. Secondly, in absence of a large
enough
local landmass, the large leaves and leaf-like structures of the canopy
provide
living space for those who wish to live in air for some time as well
as, more
importantly, providing areas for the birth and rearing of Amphisapien
children.
Often soil from the seabed is lifted up to the lower levels of the
canopy, and
this soil in conjunction with a growth of creepers and other plants,
form a
sort of pseudo-soil, which is often indistinguishable from normal,
thickly
forested land. In such cases the lower most level of the canopy is made
of a
dense growth of smaller spherical leaves that are partially submerged
and hence
help to support the weight of the pseudo-soil. These rafts of closed
leafs are
also used as nurseries, where new plants and animals can be grown using
nutrients from the tree itself before being relocated.
Accompanying the larger trees is often a number of smaller,
free-floating
plant-derived structures. These come in many forms but are generally
composed
of a large hollow gourd-like structure, partially submerged with leaf
and
branch-like structures spreading above the water and along the water
surface.
Being free-floating these often drift away to collect in the doldrums
of the
world ocean. There they get entangled in the great floating mats of
seaweed
that form in the still waters. As the gourds and floatation chambers of
the
seaweeds are filled with pure oxygen the Amphisapiens can use them to
increase
their diving time. But the gourds have another function. They float low
in the
water because they collect iron and other heavy metals dissolved in the
seawater to form nodules. The Amphisapiens harvest these nodules for
their own
ballast needs.
On land, the Amphisapiens also live in neogen trees, but these are
generally
smaller and consist of only two or three stories. Often a building is
not a
single tree, but a structure built up by dozens of smaller plant
structures
intertwined together. Few Amphisapiens choose to live permanently on
land, so
the landmasses are more like resorts or theme parks and, for a few
special
cases, the raising of children.
The areas in and around the cities are home to vast ecologies, both in
water
and above it. These ecologies are closely monitored by the local
Amphisapiens
and they often add to it and extend it, in the same way city planners
would
develop a city. The local ecology is also the local industry, with the
various
lifeforms producing most of the products used by the local populace.
The
various lifeforms include everything from slightly tweaked
versions of standard Terragen biota
to
neogen species bearing absolutely no resemblance to anything else in
existence.
As a result the trade among Amphisapiens is mostly in gene or bionano
templates
and new plants and animals. Each city generally has its own preferences
and
styles, which are often very different to those in any other cities.
The result
is that any world with a sizeable Amphisapien population will generally
have a
number of very diverse and unique ecosystems. However the Amphisapiens
sometimes indulge in creating "monobiotic ecosystems" (ecosystems
where all the lifeforms are just variations on a single original
creature) and
are credited with this style's current popularity in several
biospheres.
Bionano is widely used in Amphisapien
technology, though rarely on its
own. It is almost always found as an add-on to some other lifeform.
Many
organisms created by the Amphisapiens have bionano systems for specific
purposes like processing special substances. In developing ecosystems,
bionano
'glues' are often used. In such cases, bio-swarms are used to perform
certain
ecological roles while organisms are created or adapted to fill them.
Often
bionano is used in conjunction with microbes to act as decomposers and
recyclers. This is especially common in large or fast growing
ecosystems where
resources once used must be freed up quickly. They are also very quick
to
recycle whatever wastes are produced by their organisms and often go to
great
lengths to do so.
Unlike many bioist
clades, the Amphisapiens are not particularly fond of bioborging.
They believe bioborging to unaesthetic and sloppy. They prefer using
external biomachines
and biobots
or
in some cases to grow new body parts over a few weeks. However many
Amphisapien
societies that have spread across Terragen space have gradually begun
to accept
bioborging over the millennia, though with some reluctance.
Throughout the millennia, the Amphisapiens have given birth to sizeable number of sub-clades, but most of them are confined to a single planet or star system. Only two sub-clades have spread far enough to be of interest. They are the Icthysapiens and the Light-tails.
Icthysapiens
The Icthysapiens were the first of the groups to move away the standard
Amphisapiens genotype and are now the largest sub-clade. They were
among the
first wave of Amphisapiens to leave their homeworld to explore other
water rich
worlds in the Utopia Sphere. Many of these worlds had oceans much
deeper than
those found on their homeworld. In order to take advantage of the
depths they
abandoned the amphibian design and became fully aquatic. The most
prominent
changes include the replacement of their lungs with gill-like
structures that
occupy the chest cavity and (as they no longer have a natural buoyancy
from the
lungs) a true swimbladder instead of a ballast pouch. Their gill-like
structures are fed water through openings on the chest, which have
their own
network of counter-flowing blood vessels and act as heat exchangers to
minimize
loses in the cold, deep water. As they are fully aquatic legs became
superfluous and in the Icthysapiens the bones of the legs and the
simplified
pelvis have been joined into a single long, jointed assembly with the
bones of
the feet spread out at its end and enclosed in skin to form a flat,
horizontal
tail. They have also abandoned speech as a sound-based communication,
but have
adopted ultrasound to augment their vision and for rudimentary
signalling over
greater distances in the depths. More personal communication is done
through
their chromatophores, which in the Icthysapiens are backed by bioluminescent
organs to make them visible in the darkness of the deeper waters. Their
children are also born underwater but because of their simplified
pelvis the
foetus can be given a longer time to develop and a newborn can be
swimming with
its mother within seconds of its birth. However they still keep the
stage-based
lifecycle and are bioist. Additionally their technology is somewhat
different,
especially in building construction, where they prefer free-floating
structures
as opposed to the Amphisapien rooted design.
Later many Icthysapiens returned to Shaati Jol, where they live
alongside the
Amphisapiens. Almost a quarter of the planet's biont population is now
Icthysapien, or an Amphi-icthy hybrid. The Icthysapiens were also
fundamental
to the formation of the Society of Humanoid Swimmers (often touted as
“the aquatic
human's answer to the IPP“).
Light-tails
In the middle of the ninth
millennium
a.t. the
Red Star
'M'pire was gradually gaining ground as a strong and dynamic
biopolity. When travelling 'M'pire lums came into contact with colonies
of
Amphisapiens they both realized that they had a lot in common. Not only
were
they both strongly biocentric with meme-set of self-transformation, but
both
also used light extensively in their societies and both lived and
worked in
large groups. Over the following millennium many thousands of
Amphisapiens
migrated from their biopolity in the Utopia Sphere to the 'M'pire,
where they
were readily accepted by Farview as citizens of the 'M'pire and became
lums.
When they accepted a variant of Farview's inheritable godmod
they quickly used it to add another improvement to themselves. They
grew a tail
almost as long as their bodies. These tails have a strong musculature
and a
flat, paddle-like membranous outgrowth along the bottom, which helps
them to
manoeuvre better. But the tail was meant not so much to help in
swimming, as it
was to help in communication. The tail is almost entirely covered in
chromatophores and the photonano
organelles of the godmod. The membrane is especially rich.
The high density of chromatophores and photonano often make the tails
glow very
brightly and this has led to their name of Light-tails. When two or
more
Light-tails meet, it is customary for them to intertwine, or at least
place
their tails in contact with each other. This allows them to communicate
in a
very efficient and intimate way, and also helps the functioning of
Farview's
blue light social node. When on land the strong muscles of the tail
allow them
to hold it almost upright, but they are unable to do this for long
periods of
time. This tail is the Amphisapiens' Mark of Pride and they wear it to
signify they will always belong to the amphibian culture. No matter how
else
they may use Farview's godmod to change their form, the tail remains to
tell
the tale of their history. Their link to Shaati Jol has never been
forgotten,
in fact every Light-tail makes a pilgrimage to the peaceful waters of
their
world of origin at least once in their lives. The years they spend on
such a
trip are viewed in the same way as the nomadic journeys that are still
so
important to their culture and it is not unusual for these journeys to
be taken
with members of their siblinghood.
Due to the free breeding meme-set of the 'M'pire the Light-tails are now widespread and productive members of the 'M'pire community. Most of the aquatic habitats in the 'M'pire have a sizeable population of Light-tails. This clade also holds the distinction of giving rise to highest number of transapients among the Amphisapien sub-clades. This is not really surprising, considering the easily available opportunities for ascension in the 'M'pire.
