      For some organisms who have characters that evolved from different ancestral but perform similar or same functions eg wings of bats, birds and insects, i just wondering how this homologica existance in the animal Kingdom would contribute to Darwins theory of evolution. Any thoughts would help. Thanks.

      Homologous traits are similar because they are derived from a common ancestor, while analogous traits are similar because natural selection (Darwin) has favored similar adaptations to similar environments.
      In the example you gave, wings of bats and birds- also eyes in fish v/s say eyes in octopus or the eyes of crocodiles v/s hippos, the similarity in the traits is due to convergent evolution, not descent from a common ancestor.

      Afele, does this make the muddy water clear?
      Did it answer your question.
      The above post is how i understand the stuff, i could be proven wrong.

      Yeh, just because 2 lawyers are both wearing suits, doesn’t mean that that one could’nt have come from a farming family and the other didn’t. Both species have found the same solution, which gives benefits, for a similar environment.
