How to test an evolutionary hypothesis about disease

Such proximate explanations are also needed, but they are not a substitute for an evolutionary explanation for why the body is the way it is. Evidence about prox ...

Other individuals may have alleles which put them at a selective disadvantage and are said to be “unfit”. The “fit” individuals survive whilst the “unfit” die (natural selection!) in the strug ...
