Convergent cosmological evolution

  1. May 28, 2005 #1
    There are many examples of convergent evolution here on Earth, such as the separate development of wings on birds, bats and insects.

    I propose that the midpoint of evolution be marked by an equivalence between convergent and divergent adaptations.

    For the universe as a whole, could isolated biological systems be evolving convergently, such that the anentropic adaptation to their physical environments eventually recreates more similar than disparate characteristics?

    I think no because evolution is based on environmental conditions. Bats, birds and insects all developed wings because they needed it in all their environments, (there's air everywhere). But lava tolerance wouldn't devolop in a species that doesn't live in a volcanic ecosystem. So for what you propose, there would need to be some kind of uniform and universal ecosystem, otherwise "convergent evolution" proof like
    wings is a coincidence due to a similarity between otherwise different environments.

    On another planet, the aliens would likely have eyes just as we do, because their planet also reflects light radiation. They wouldn't have gills though if their planet didn't have water, and so all species evolve independently.
