Question

The cytochrome c in both horses and pigeons differs from the human protein at 12 locations. Based on this data, you might infer that horses ad pigeons are closely related. What could you do to support of refute this hypothesis?

Answer 1

To check if the hypothesis is correct or not, one must create a Genetic Phylogeny. This would give the strongest evidence of finding a relationship between species. However, phylogeny based on Cytochrome C have discrepancies on traditional phylogenies. Therefore, the hypothesis made can easily be refuted.
