This diagram shows that embryos of certain species develop almost identically in the earliest stages of embryonic development. these physical similarities indicate that there are also genetic similarities among these organisms. the physical and genetic embryological similarities among these organisms suggest that they a. descended from a common ancestor. b. have multiple vestigial organs in common. c. are members of the same genus. d. hunt and breed in similar habitats.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
