I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.

Archaeological geology as a science had to precede the proposal of evolution, as an understanding of the immense age of the earth is necessary to understand evolution.

Cuvier established amongst the scientific community the fact of extinction.

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.

[3] Adaptation is genetically based and so leads to phenotypic changes that accumulate over time; [4] Speciation (species formation) evolves through reproductive isolation and (genetic) divergence of populations; [5] Genetic changes through natural selection lead to new species and eventually new taxa .

Scientists now have accurate methods (see below ) for dating fossils.

methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.

The evolution of a species is linked to the environment.

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