WebNatural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift. Darwin’s grand idea of evolution by natural selection is relatively simple but often misunderstood. To see how it works, imagine a population of beetles: There is variation in traits.

From projecting human intentions onto animals or using language that suggests natural processes have purpose, scientists are taught to avoid “anthropomorphising”. Yet, this kind of thinking can have significant explanatory power – think of Richard Dawkins’ famous …
WebMutation, migration, genetic drift, and natural selection are all processes that can directly affect gene frequencies in a population. Imagine that you observe an increase in the frequency of brown coloration genes and a decrease in the frequency of green coloration genes in a beetle population.
WebIt happens to ALL populations — there’s no avoiding the vagaries of chance. Earlier we used this hypothetical cartoon.
