: 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)

::BTW, the graphic at that link (skeletal structures of pterosaurs, bats and birds with emphasis on their wings) can be seen as a bit of a refutation of the text "Convergent evolution [...] presents the following conceptual problems. First, it requires that random chance produce the same outcome in at least two independently occurring instances, which is substantially less likely even than doing so once. Such evolutionary coincidence is a less plausble explanation than one that evolutionists assume away, namely, a common Designer." The designs of the arm/hand bones to make the wing are completely different in all three. Also, insect wings are boneless. This does not imply a common designer. -- [[User:Limulus|Limulus]] 19:05, 10 February 2011 (EST)
