sapiens (including Neanderthals and Cro-Magnon) (see the modern taxonomic classification of humans).

This formed the foundation of the neo-Darwinian evolutionary theory.

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.

Primate taxonomy (see books: phylogeny, taxonomy, systematics) is in a state of flux due to the discoveries made in primate genetics.[2] 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 .[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 .Living orders of placental mammals , be it bats, humanity, whales or camels, have as their common ancestor a small insectivore creature that went through a major phase of adaptive radiation during the Early Cenozoic Era .We humans are first animals, then mammals, then primates.
