Assignment Task:
Paraphrase and add detailed explanation Evolutionary processes, particularly natural selection and genetic variation, continue to influence modern human traits and health outcomes. For example, instances of genetic resistance to HIV highlight how human populations adapt to environmental challenges. Certain genetic mutations, such as those in the CCR5 gene, have been shown to confer resistance against the virus. This showcases natural selection at work, where individuals with advantageous traits are more likely to survive and reproduce, promoting these traits in subsequent generations. In addition to disease resistance, other phenotypic changes, like increasing human height, reflect the interaction of genetics with environmental factors such as nutrition and health care. Similarly, the declining prevalence of wisdom teeth in modern humans suggests that as our diets have evolved and become softer due to agricultural practices, there has been less evolutionary pressure to maintain this trait. This ongoing interplay between our genetic background and environmental influences illustrates how evolutionary processes shape human biology, driving our adaptation to contemporary challenges while influencing health trajectories in multifaceted ways.
