List of useful evolution resources about this topic.

Learning Goals:

At the end of this session you will know:
• The difference between selective and nonselective mechanisms for evolution

• That natural selection acts on individuals, but its actions result in evolution of populations

• How natural selection results in adaptations, both simple and complex

• The sources of genetic variation in a population

• How natural selection and sexual selection interact in a population

• The biological concept of species and how new species are formed

• Examples of coevolution and convergent evolution
