Convergent Evolution
When a trait develops independently in two or more evolutionary sequences or groups of organisms; e.g. the development of skin-flap wings in pterodactyls and bats. Mathematically, this refers to dynamic systems settling into an attractor.

    An archetype or state that is characterization of the long-term behaviour of a dissipative dynamic system. Over long periods of time, the state space of some dynamical systems will contract toward this region. The Archailects are said to be dynamic systems that characterize particular attractors. Likewise, certain biological forms, certain memes, certain technological solutions, and so on, are known to have emerged independently on completely different planets or among different alien races.
