Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

Hace 2 días · Learn about the process by which human beings developed from now-extinct primates, and the fossil evidence and scientific models for this history. Explore the human lineage, the human family bush, and the human evolutionary pathways.
Hence, in genetic terms evolution consists of changes in the organism’s hereditary makeup. Evolution can be seen as a two-step process. First, hereditary variation takes place; second, selection is made of those genetic variants that will be passed on most effectively to the following generations.
