Based on the below diagram and other information from your text, what is the most likely (e.g., most parsimonious) explanation for the evolution of flight in vertebrates?
A. The common ancestor of all terrestrial vertebrates was wingless and wings evolved independently three different times: in bats, in pterosaurs and in the common ancestor of birds and dinosaurs.
B. Wings evolved once in vertebrates (e.g., the common ancestor of all terrestrial vertebrates had wings) and wings were subsequently lost in all but three lineages: bats, pterosaurs and birds.
C. The common ancestor of all terrestrial vertebrates was wingless and wings evolved independently three different times: in bats, in pterosaurs and in birds.
D. The common ancestor of all terrestrial vertebrates was wingless and wings evolved independently two different times: once in bats and once in the common ancestor of birds, pterosaurs and dinosaurs.
E. The common ancestor of all terrestrial vertebrates was wingless and wings evolved independently three different times: in bats, in birds and in the common ancestor of pterosaurs and dinosaurs.

A. The haploid cells produced by spermatogenesis are genetically diverse from the original parent cell and the haploid cells produced by oogenesis are genetically identical to the original parent cell. B. Spermatogenesis occurs in the ovaries and oogenesis occurs in the testes. C. Spermatogenesis results in the production of four haploid sperm cells and oogenesis results in the production of a single haploid egg cell. D. Spermatogenesis produces haploid cells and oogenesis produces diploid cells. E. Spermatogenesis begins while the man is still a fetus, but oogenesis does not begin until after a woman reaches puberty.
