For example, in many cities, Diamond says, scientists can date the onset of high levels of warming from industrialization.Describe the steps which led to the origin of life (organic molecules form, macromolecules polymerize, a hereditary mechanism develops, membrane-enclosed protocells form). Apply the principles of evolution by natural selection to pre-biotic scenarios. The origin of life is a mystery, the ultimate chicken-and-egg conundrum (R Service, 2015). Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.” So, he reasoned, variations must occur in nature that are favourable or useful in some way to the ...
