Answer #1

Option b is the correct answer. Phylogeny is the branch which deals with the evolutionary development and diversification of a species or group of organisms, or of a particular feature of an organism. It is a proposal of how organisms are related by their evolutionary history.

Ontogeny is the study of the development of an individual organism from the earliest stage to maturity stage

Ancestry is the study of background of an organism.

Paleontology is the study of fossils.

Suppose that in the evolutionary history of these organisms, the mark "c" indicates the appearance of and strong selection for the trait "extra hairy legs." Is it possible that leaf-cutter bees have perfectly smooth legs, with no hair at all, when all of the other lineages descended from ancestral population "c" do have hair? If so, explain how that could have evolved. If not, explain why not.
