At the onset of the 20th century, most scientists had accepted the great antiquity of the earth, the theory of evolution and that humanity had evolved from an ape ancestor, but by 1908 the fossil evidence of early man was scarce.Biologists included principles from genetics in evolutionary theory during the 1920s and 1930s.Evolution & Ecology " (see its HOME PAGE .) The result is that some areas, such as the glossary are shared.Widgets Human evolution from an ancestral primate species is not a vague hypothesis, but a historical fact.

Primate taxonomy (see books: phylogeny, taxonomy, systematics) is in a state of flux due to the discoveries made in primate genetics.

Once multicellular organisation became possible as atmospheric oxygen levels rose, the early multicellular organisms rapidly diverged into many adaptive forms.

Mass extinction events and an organism's unique adaptations mark the history of evolution, both of which may lead to adaptive radiation.

The evolution of a species is linked to the environment.

Adaptation is a continuous response to the environment by changeable species.
