Only after this, did God breathe his Spirit into Adam.
In our modern view, the creation of Adam must conform with the evolutionary creation of humanity.
God first completed the physical and biological constitution of humanity.
 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.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.( Adaptive radiation is the evolution from an unspecialised ancestral stock of many different species that adapt to a variety of ecological roles (see books)).Mammals and subsequently humanity may not have become dominant on earth had it not been for the global catastrophe that led to the extinction of the dinosaurs 65 million years ago.africanus (Dart, 1925) (including small brained australopithecines) (see books), H.
