The Dynamics of Genetic Drift and Human Evolution

This chapter explores genetic drift using the example of a recessive allele for colorblindness in small populations and contrasts it with new fossil discoveries that challenge traditional views of human evolution. It highlights the coexistence of multiple hominid species and the ongoing work of paleoanthropologists in unearthing artifacts that reshape our understanding of ancestry. The chapter also discusses the impact of modern medicine on natural selection and how contemporary society influences human evolution amid emerging diseases.
