ANTH 2 Lecture Notes - Lecture 5: Sickle-Cell Disease, Social Evolution, Evolutionism
Document Summary
Natural selection - the mechanism of evolution. Organisms are trying to get things survive; be successful and reproduce. Everyone is competing with one another for resources. The way that their physical composition would relate to the environmental conditions in which they lived in. Biological traits will be different than that of others. Population will look different, but will still have a variety. No foresight to evolution: no necessary destination for evolution. Relationship between people, conditions, and shift overtime. Variety is inherited - wide array of physical traits. Strong beaks were best able to survive drought conditions. When rain fell, shifted back (temporary condition) Two hbs = lethal sickle cell anemia. One of each (heterozygous) = nonlethal sickle-cell syndrome. Humans change their environments, environments change humans. Humans create social relationships and ideas to deal with their environment. Not a relationship between biological individuals and conditions. How to organize together and make tools in order to deal with their environment.
