As modern humans migrated to different environments, the environments challenged their ability to adapt. When the environmental conditions were constant and lasted for many generations, human populations adapted through biological evolution by natural selection.
To learn more about human biological adaptations, explore the The Palomar College Web site which has specific introductory information on climatic, altitudinal, and nutritional adaptations.
Then choose one human biological adaptations to research further. Some possibilities are lactose intolerance, skin color, climate adaptations, or sickle cell anemia. Here are a variety of resources where you can begin your investigation:
Summarize your findings about the biological adaptation.
