Process of relative dating

Only after this, did God breathe his Spirit into Adam.There are thus two aspects of the human personality, the physical constitution and the spiritual constitution.( 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.Once multicellular organisation became possible as atmospheric oxygen levels rose, the early multicellular organisms rapidly diverged into many adaptive forms.Mass extinction events and an organism's unique adaptations mark the history of evolution, both of which may lead to adaptive radiation.[2] 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 .[3] Adaptation is genetically based and so leads to phenotypic changes that accumulate over time; [4] Speciation (species formation) evolves through reproductive isolation and (genetic) divergence of populations; [5] Genetic changes through natural selection lead to new species and eventually new taxa .

methods rely on characteristic faunal and geological patterns to bracket the period when the fossil existed.Living orders of placental mammals , be it bats, humanity, whales or camels, have as their common ancestor a small insectivore creature that went through a major phase of adaptive radiation during the Early Cenozoic Era .We humans are first animals, then mammals, then primates.Evolution & Ecology " (see its HOME PAGE .) The result is that some areas, such as the glossary are shared.Widgets Human evolution from an ancestral primate species is not a vague hypothesis, but a historical fact.
