  1. Positive natural selection, or the tendency of beneficial traits to increase in prevalence (frequency) in a population, is the driving force behind adaptive evolution.

  2. 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.
