Detailed explanation-1: -Fossils, anatomy, embryos, and DNA sequences provide corroborative lines of evidence about common ancestry, with more closely related organisms having more characteristics in common. DNA underlies the similarities and differences in fossils, anatomy, and embryos.
Detailed explanation-2: -Q. Scientists think that dolphins and whales may have evolved from a common ancestor. What evidence supports this hypothesis? They swim the same way.
Detailed explanation-3: -Baleen whales, however, only possess teeth in the early fetal stage and lose them before birth. The possession of teeth in fetal baleen whales provides evidence of common ancestry with toothed whales (and all other mammals).
Detailed explanation-4: -The similar construction of these appendages indicates that these organisms share a common ancestor. Another type of evidence for evolution is the presence of structures in organisms that share the same basic form.
