Detailed explanation-1: -Which of the following features did whales possibly inherit from a four legged ancestor? Hip bones.
Detailed explanation-2: -Which of the following lines of evidence shows that whales are descended from a land-dwelling, four-legged ancestor? Whale embyros have similar structure to embryos of land-dwelling mammals, birds, and reptiles.
Detailed explanation-3: -Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
Detailed explanation-4: -DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
