Between the mid-1930s and mid 1940s geneticists, systematists and palaeontologists collaborated to create a united approach to evolution, the "Modern Synthesis".
Ernst Mayr reduced all the hominid (human ancestor: (see hominid books)) fossil records to three species, A.
africanus (Dart, 1925) (including small brained australopithecines) (see books), H.
erectus (including the Java and Peking hominids - the archetypal Missing Link) and H.
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.
Our hominoid line, humans, gorillas, chimpanzees and lesser apes, is one among the superfamily Hominoidea.
See the taxonomic table of primates for two comparative classification shcemes.
I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.
 Natural selection, gene flow and random genetic drift (the random change in gene combinations with each generation) drive evolution, resulting in a change in gene frequencies within populations .
 Adaptation is genetically based and so leads to phenotypic changes that accumulate over time;  Speciation (species formation) evolves through reproductive isolation and (genetic) divergence of populations;  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.
