Evolution only gained significant momentum after the theory of evolution, published by Charles Darwin in November 1859, implied that man was merely another product of life on earth, with origins shared by the other creatures and not its ultimate purpose. Wallace proposed the same theory at a joint presentation to the Linnaean Society in London .
Without the universal acceptance of the principle of evolution, there is no chance for the serious proposal of 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 a continuous response to the environment by changeable species.
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.
sapiens (including Neanderthals and Cro-Magnon) (see the modern taxonomic classification of humans).
This formed the foundation of the neo-Darwinian evolutionary theory.
