Talk:Convergent evolution (view source)

, 03:04, February 10, 2011→Convergence vs Homology
It currently says "In evolutionary biology, convergent evolution is the process by which two organisms or taxonomic groups have a character in common due to independently adapting to a similar environment or niche, not by homology." but then mentions "morphology between bats and birds" Now, while flight is a convergent characteristic between the two (as they did not share a flying common ancestor), their flight limbs are homologous (both forelimbs in the vertebrate body plan)... insect wings are analogous to birds and bats; while they both do the same thing (enable flight by flapping) they are an entirely different structure. So... this should probably be cleaned up. -- [[User:Limulus|Limulus]] 21:59, 9 February 2011 (EST)

: There is a very nice quote on Wikipedia [http://en.wikipedia.org/wiki/Homology_%28biology%29#Homology_of_structures] that explains what I'm getting at: "The wings of pterosaurs (1), bats (2) and birds (3) are analogous as wings, but homologous as forearms." -- [[User:Limulus|Limulus]] 22:04, 9 February 2011 (EST)
