Evolution and Human Origins

Evolution and Human Origins. Common Ancestors. Closeness of relationship is reflected by greater DNA sequence similarity i.e. the closer 2 species are in relation to each other, the more DNA sequences they will share Similar sequences are likely to have arisen from a common ancestor.
