If you like this, do yourself a favor and go watch the entire Human Behavioral Biology course from Standford, it's also taught by Sapolsky: https://www.youtube.com/watch?v=NNnIGh9g6fA

What I think makes the course so good is that it gives you a brief but solid introduction to many different fields:

    - Behavioral Evolution
    - Molecular Genetics
    - Behavioral Genetics
    - Ethology
    - Neuroscience
    - Neurology and Endocrinology

And then combines all of those to try to make sense of human behavior, by looking at animal and human behavior from all these different lenses.
