This is the second in a series of modules which detail the research of Charles Darwin and evolutionary theory. This module continues with a discussion of the processes that led to Darwin's formulation of the theory of natural selection.

The purpose of this lesson is to research artificial selection. During this lesson, we will use fast growing plant crossing to model traditional agricultural practices and we will use Punnett squares to predict plant crossing outcomes. We will also use online simulations to learn about current biotechnology techniques used to make genetically modified crops. We will compare traditional agriculture to current biotechnology techniques that are being used to create pest resistant crops. We will discuss how artificial selection such as selective breeding and genetic engineering can impact organisms over time.

There are lots of ways that evolution happens, and natural selection is just one of them. In this episode of Crash Course Biology, we’ll find out how this process works and shapes traits in all living things —from ginkgo trees to howler monkeys. We’ll also learn how extra-grippy toes help some lizards survive hurricanes.
