This one focuses more on evolutionary psychology, which was explored a little bit on his last album, The Rap Guide to Evolution. It’s a field that gets a lot of criticism, and rightly so. We can find the fossils and even some DNA of our ancestors by digging up samples, but we don’t get much insight on ancient hominid consciousness from them. It’s fun to hypothesize about how our current personality quirks and odd behaviors might have been based on how earlier humans evolved on the Serengeti, but that largely fails when it comes to putting those hypotheses to a good test. And as a result, there’s less quality control and you tend to see people misusing the field in order to further one or another social or political agenda.
I’m not saying that’s what this album does, but it’s a good reason to take this kind of stuff with a grain of salt whether you hear it on a rap album or from someone in a more serious venue.
