ANT208H1 Lecture Notes - Lecture 4: Bipedalism, Mutation, Heritability
Document Summary
The theory of natural selection, the relationship between genetics and groups of populations. We have underlying genes that have come from our ancestors but there are types of limitations that we cannot compete with. i. e swimming like dolphins. Some of our vulnerabilities to disease stem from these limitations. As for all organisms, human evolution is based on: problems than changes in genes later in life. Across generations there are cross variations that stem from variation in genetics through reproduction. Reproduction as a biological capability to reduce death among populations. Longevity of the genes that are passed on through generations (genes make it through evolutionary time whereas some disappear). Not all genes promote health, can cause disease (i. e. stress): mutation, gene flow + drift, selection (differential survival of genes) Selection maximizes reproductive success (not the same as producing offspring) = fitness. It only maximizes health and longevity if they maximize fitness.
