Explanation:

In this lecture you learned that due to evolutionary descent, organisms share many of the same genes and proteins. However, distantly related organisms have more DNA differences than closely related organisms.

Organic evolution general refers to the descents, with modification, of organisms from common ancestors. Hence, organisms that share the same ancestors share several similar genes and proteins due to their common lineage. The closer the organisms, the more similar their genes and proteins, and the distant the organisms, the more dissimilar their genes.
