Darwin's finches show only microevolution (Talk.Origins)

Claim CB901.3:

Darwin's finches show only microevolution. In a long-term study, the changes were small and oscillated back and forth. They show no evidence for macroevolution.

CreationWiki response:

All this shows is that the claim as written is correct. The fact that they oscillated back and forth, demonstrates that changes observed are just part of the finches' pre-existing genetic potential.

That is probably an accurate conclusion, but that common ancestor was still a finch. It is reasonable to conclude that all finches are members of the same Created kind.

Talk Origins can call it evidence for macroevolution all they want, but the real point is that they are all finches and their common ancestor was a finch. Actually their common ancestors would have been the seven finches that came out of Noah’s Ark.
