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.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.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.This environment has a living (other animals) and non-living component (e.g. Widgets A unique adaptation usually precedes the entry into a new niche .Tool use by our early ancestors is one such adaptation.[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 .Very simply, there are five basic principles to this theory: [1] Variation has a genetic origin (i.e.is heritable) and arises through processes such as mutation and recombination.


  1. Estimates of the total heat flow from Earth’s interior to surface span a range of 43 to 49 terawatts TW a terawatt is 10 12 watts. One recent estimate is 47 TW.

  2. How do geologists date rocks? Radiometric dating! Radioactive elements were incorporated into the Earth when the Solar System formed.

  3. Evolution & Creation science Why biological & geological scientists disagree with religious conservatives

  4. Humanity has evolved from a common ancestor with the chimpanzee. Human evolution traces this evolutionary history from non-human apes to technological man.

  5. As with any experimental procedure in any field of science. these generally reliable methods. young-Earth literature. Radiometric dating is based on.

  6. Radiometric Dating. explain the principles of radiometric dating and its application in determining the age of Earth in this video segment from A Science Odyssey.
