Explanation:

Biological evolution is the set of changes in phenotypic and genetic characters of biological populations through generations. This process has caused the diversity of life forms that exist on Earth from a common ancestor. Evolutionary processes have produced biodiversity at every level of the biological organization, including those of species, population, individual organisms and molecular (molecular evolution). All life on Earth comes from a last universal common ancestor that existed between 3800 and 3500 million years ago.
