 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 .The evolution of a species is linked to the environment.
Only after this, did God breathe his Spirit into Adam.methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.At the onset of the 20th century, most scientists had accepted the great antiquity of the earth, the theory of evolution and that humanity had evolved from an ape ancestor, but by 1908 the fossil evidence of early man was scarce.Mass extinction events and an organism's unique adaptations mark the history of evolution, both of which may lead to adaptive radiation.( Adaptive radiation is the evolution from an unspecialised ancestral stock of many different species that adapt to a variety of ecological roles (see books)).Cuvier established amongst the scientific community the fact of extinction.
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 .We humans are first animals, then mammals, then primates.In our modern view, the creation of Adam must conform with the evolutionary creation of humanity.Biologists included principles from genetics in evolutionary theory during the 1920s and 1930s.Between the mid-1930s and mid 1940s geneticists, systematists and palaeontologists collaborated to create a united approach to evolution, the "Modern Synthesis".Widgets Human evolution from an ancestral primate species is not a vague hypothesis, but a historical fact.
