Biologists study the physical structures of species and compare them to its fossil record. New technology allows scientists to examine the DNA of different species, and they have discovered that species that appear very different actually share many DNA sequences. What does this evidence suggest? A. These species may share a common ancestor. B. DNA sequences are almost identical in every species. C. These species must be from the same geographical region. D. DNA sequences do not determine species' physical characteristics.
