An adaptation is any variation that can increase one’s biological fitness in a specific environment; more simply it is the successful interaction of a population with its environment. Jan 12, 2017. A clear example of adaptation both cultural and environmental is the increase in myopia in our western cultures compared to developing countries. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Steward was interested in whether adjustments of human societies to their environments required specific types of behaviors or whether there was a wide variety of behaviors. These changes were initially viewed as good, but recent research shows that these adjustments are a series of trade-offs, and that there are costs and benefits associated with the choices made. Anthropology has a long history of exploring the facets of human-environment interactions. The ancient Greek philosopher Heraclitus originated the theory that things are constantly changing -- and the saying, "The only constant is change," is attributed to him. Environments shape the genetic landscape of the populations that inhabit them. 2. Coherent Cookies Policy: our aim is customer satisfaction!
