Question

California sea lions and harbor seals are two related but very different species that are both common along the Pacific Coast of North America. You suspect that the differences between these animals are the result of evolutionary development rather than macromutation. Which of the following observations would support this hypothesis? (a) Pollution over the last century means that both species may have been exposed to mutagens more frequently during that time (b)Harbor seals are spotted, whereas California sea lions have a uniformly black coat (c) Whole-genome analysis suggests that mutation rates have been relatively low in each species over the last several million years of evolution (d) Both species have the same hox genes, though each species has unique SNPs in these genes (e) California sea lions are highly social, while harbor seals congregate in smaller groups.
