Thank you ILoveTTATT2.
I tend to review topics in multiple sources and then try to write it up as succinctly as possible. TalkOrigins is an excellent resource. I think I mostly used Dr Zachery Moore's podcast transcript for this one but he does refer to TalkOrigins.
If every animal had identical amino acid sequences in their cytochrome C proteins that would be consistent with creation. If they all had unique sequences that would be helpful to creationism as well. The evidence for evolution is that the degree of difference can accurately be predicted by the closeness of evolutionary relationship of species. That is very powerful evidence.
