Detailed explanation-1: -Protein sequences in one organism that resemble those of another suggest that they share a common ancestor. If the Evo-Dots lab had continued for another 5 generations, the number of different color populations would most likely decreased.

Detailed explanation-2: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor.

Detailed explanation-3: -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.

Detailed explanation-4: -When a recent common ancestor is shared between two organisms, they are said to be closely related. In contrast, common descent can also be traced back to a universal common ancestor of all living organisms using molecular genetic methods.
