Category:Evolution

Evolution is the idea that biological populations change over successive generations as specific traits are reproduced or "selected" (inherited) for their adaptation to particular environments. These changes tend to be slow and cumulative, but are not teleological – that is, they do not have a predetermined end-point, but are exclusively the result of the selection of random mutation. The theory of evolution was popularized during the mid-nineteenth century by Charles Darwin in his book  On the Origin of Species.
