Indeed, both Wallace and Darwin came to understand natural selection not by studying the flora and fauna of a single region but by comparing patterns of variation across geographic regions.

As Charles Darwin (1859) argued in On the Origin of Species, if the following conditions are met, natural selection must occur: There is variation among individuals within a population in some trait.

Continuous variation is represented as a histogram ... Charles Darwin used the theory of natural selection to explain the process of evolution. Evolution is a continuing process of natural ...

Writing in The Guardian, Dr. Rickard explains, “Natural selection requires variation. It needs some individuals to thrive more than others.” “So the improved survival prospects around the ...

I was interested in it on a genetic level. Charles Darwin said evolution occurs by natural selection in the presence of continuous variation, but he never proved the occurrence of natural selection in ...
