Neo Darwinism
The neo–Darwinian theory of evolution is the "modern synthesis" of Charles Darwin's theory of evolution by natural selection combined with the
Gregor Mendel's theory of genetics. This modern theory of evolution is the connection between genes and mechanisms of evolution, specifically
natural selection. It can also be described as the mechanisms that may lead to the changes in the frequencies of alleles found in a population. The
neo–Darwinian theory proclaims that all living organisms share a common ancestor and the evolutionary process is gradual. Evolution is
mechanised by natural selection, gene flow, genetic drift and human intervention which results in speciation (the formation of a new species).
Natural selection, the key evolutionary...show more content...

bacteria (mostly in developing nations) and inadequate surveillance (patients not completing their course of antibiotics and the strongest/resistant
