The evolution of a species is linked to the environment.Adaptation is a continuous response to the environment by changeable species.Social forces appear to have directed much of the evolution of humanity but we are still subject to natural selection.Primate taxonomy (see books: phylogeny, taxonomy, systematics) is in a state of flux due to the discoveries made in primate genetics.Very simply, there are five basic principles to this theory:  Variation has a genetic origin (i.e.is heritable) and arises through processes such as mutation and recombination.Only after this, did God breathe his Spirit into Adam.
 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 .
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.
sapiens (including Neanderthals and Cro-Magnon) (see the modern taxonomic classification of humans).
This formed the foundation of the neo-Darwinian evolutionary theory.
Once multicellular organisation became possible as atmospheric oxygen levels rose, the early multicellular organisms rapidly diverged into many adaptive forms.
