Radiometric dating on fossils updating p300 an integrative theory of p3a and p3b
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.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.
Widgets Human evolution from an ancestral primate species is not a vague hypothesis, but a historical fact. 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 .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.
Very simply, there are five basic principles to this theory:  Variation has a genetic origin (i.e.
