Positive natural selection, or the tendency of beneficial traits to increase in prevalence (frequency) in a population, is the driving force behind adaptive evolution.
Mar 14, 2021 · In this chapter, we discuss methods and models that have been used to better understand how selection has impacted human variation and review studies of natural selection in humans and the stories they reveal about human history.

Oct 6, 2017 · Ultimate causes are those of greater relevance in evolutionary ‘human natures’ questions as they reflect the effects of natural selection and are thus statements about the fitness, functional impact, origins and selective mechanisms/histories of the traits in question.
