The amino acids sequences for hemoglobin in humans and gibbons differ by one amino acid. This molecular similarity in these two species indicates that they___. A) are the same species B) were recently in the same species C) are not closely related D) share a common ancestor
D because the closer they are geneticaly, the more related they are. A cactus and a squirl have little to no similer genetic makeup so A human and a gibbon that already have a conspericy around them as to evolution would have closer makup.
