This clip illustrates how different breeds of dogs were made by artificial selection. Neil deGrasse Tyson also discusses evolution's role in this process.
In this clip, Charlie suggests using an evolutionary algorithm to search for abnormal behavior after a murder occurs in a video game with a real-life component. Evolutionary algorithms imitate the biological process of natural selection to find optimal solutions.
Hank provides background information on the biologist who contributed to evolutionary history: Charles Darwin. He also explains the four principles of Darwin's idea of natural selection, which are variation, heritability, struggle for existence, and survival and reproduction rates.
