Human adaptations in periglacial Eurasia at the close of the Pleistocene, from ~ 15,000 to 10,000 B.P., are of special interest because they not only reflect lifeways during a period of climatic and environmental changes, but also document great variability. In the ensuing discussion, I ...

Genetic drift leads to a loss of genetic variation, which limits what selection can do to produce adaptations if the environment changes. Keeping these two issues in mind, greatly reduced populations may be at increasingly greater risk for genetic reasons, leading to further declines. ...

revealed the loss of theBCO1 gene, likely an adaptive change in response to a specialized diet of vitamin A-rich but beta-carotene-poor squid. This approach provided valuable insights into specific genetic variations, functional consequences, evolutionary history, and unique adaptations of sperm ...
