- Evolution does not change any single individual. Instead, it changes the inherited means of growth and development that typify a population (a group of individuals of the same species living in a particular habitat). Parents pass adaptive genetic changes to their offspring, and ultimately these changes become common throughout a population.

Charles Darwin and Alfred Wallace (1858) famously proposed that positive selection could explain the many marvelous adaptations that suit organisms to their environments and lifestyles, and this...
While recognizing that non-genetic mechanisms of adaptation such as developmental plasticity and cultural evolution are powerful forces, this review focuses on recent developments related to the detection, classification and interpretation of natural selection in the human genome. Selective sweeps.

Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.
As human populations settled different areas around the world, they evolved to adapt to their local environment. Such adaptations included changes in skin pigmentation, retention of lactase expression as adults, and physiological adaptations to cold or to high altitudes.
“[All] organisms adapt to their environment, and in humans much of our environment is defined by our culture. Hence, cultural change can actually spur on adaptive evolution in humans”, wrote evolutionary biologist Alan Templeton at Washington University in St. Louis, MO, USA. 1. Following this argument, culture, social learning and ...
Nov 23, 2020 · Our theoretical work on the recurrent structures of human social networks and how they foster and transmit adaptations has implications for the emergence of climate-change adaptation on a global scale (Jones et al., 2021b).
