Natural Selection in a Nutshell:
- living things produce more offspring than the finite resources available to them can support
- thus living things face a constant struggle for existence
- the individuals in a population vary in their phenotypes - this variation is a result of sexual reproduction
- some of this variation is heritable - it is a reflection of variation in genotypes (DNA)
- those variants best adapted to the conditions of their life are most likely to survive and reproduce themselves - survival of the fittest
- to the extent that their adaptations are heritable, they will be passed on to their offspring
