Detailed explanation-1: -Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

Detailed explanation-2: -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-3: -DNA is used as evidence for evolution because it shows that all species have one common ancestor. The more closely related the two species are, the more similar their DNA is, indicating they evolved from a recent common ancestor.

Detailed explanation-4: -Evidence of common ancestry comes from several different sciences like-biogeography, geology, anatomy, chemistry, genetics, and even molecular biology. Biogeography can be defined as the study of the geographical distribution of animals and plants in different parts of the earth.
