Heredity and Evolution
In evolutionary terms, we have more in common with a:
monkey
rat
chimpanzee
gorilla
chimpanzee
Humans did not evolve from monkeys. Humans are more closely related to modern apes than to monkeys, but we didn’t evolve from apes either. There existed a common ancestor for both the chimpanzees and humans, about 5-8 million years ago. Later, the two lineages diverged into two separate lineages. One of these lineages ultimately evolved into chimps and other apes, and the other evolved into early human ancestors called hominids.
