Primate myoglobin sequence alignment
Primate myoglobin sequence alignment


Note that human and chimp sequences are almost identical. The red guenon sequence diverges slighly more. In general the more a mammal diverges evolutionarily from Homo sapiens, the more its myoglobin sequence diverges.

Does sequence divergence reflect evolutionary divergence? If so one expects other protein and noncoding sequences to show corresponding divergence. They in fact do. Regardless of what sequence one chooses one infers the same evolutionary history.

Do these differences reflect random mutation or design? If the former one expects sequence differences to be primarily in nonfunctional regions of the protein. If the latter one expects differences to be primarily in functional regions. Differences are in fact primarily in nonfunctional regions.
