Question
Chapter 21.6, Problem 1CC
Summary Introduction
To analyze: The similarity of the genome of monkeys with mice and humans.
Introduction: Chimpanzees are considered the closest relative to humans because humans and chimpanzees diverged about 6.5 and 7.5 million years ago after which multiple changes takes place in the genomes as insertions, deletions, duplications, chromosomal rearrangement, etc. In the case of mice, many genes of mice and humans share a common function, and the internal development of humans and mice is like the development of circulatory, reproductive, digestive, hormonal, and nervous systems.
