Congratulations! This is our last episode of our section on Evolution and Genetics, which puts us at the halfway mark of CrashCourse Biology. So far we've learned about DNA, genetics, natural selection, how cells multiply, populations, speciation, replication, respiration, and photosynthesitation. I'm so proud of you. But I couldn't let this section end without discussing the iscussion that everybody can't help but discuss these days: Evolution. It's a thing. It's not a debate. Evolution is what makes life possible. It allows organisms to adapt to the environment as it changes.
