4 components of natural selection.

INTRODUCTION. Sexual selection has a contentious history. Originally, sexual selection was proposed by Darwin (1859, 1871) to explain the evolution of traits that do not appear to increase longevity or fecundity, and so would not be favored by natural selection.Whilst the rest of the Darwinian view of evolution has been widely accepted, …
