WebDec 24, 2024 · Two segments of DNA can have shared ancestry because of either a speciation event (orthologs) or a duplication event (paralogs). Homology among proteins or DNA is often incorrectly concluded on the basis of sequence similarity. The terms “percent homology” and “sequence similarity” are often used interchangeably. WebSep 4, 2024 · 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. Look at the diagram in Figure \(\PageIndex{5}\).
