Biological evolution. Definition

Medical Definition: Biological evolution

Molecular changes first, then phone, and finally of organisms throughout history as a result of mutations in DNA, its replication and selection processes. Acquired characters are not inherited in life. The human species shares 98.40% of the DNA in two species of chimpanzee, the common and pygmy. Evolution depends mainly of mutations in regulatory genes of the structural genes that make you turned on or off, rather than mutations in structural genes themselves.
