Given that we are focusing on behavioral genetics this week, I thought this article might be an interesting addition. It basically uses phylogenetic analysis to explore the extent to which females are drivers of social evolution in primates and concludes that they are the key sex to focus on when considering primate social behavior changes over time. There are also, however, some interesting theoretical assumptions about evolutionary and phylogenetic analysis that this paper's conclusion rests on that might be worth thinking about in tandem with some of the studies brought up this week. (For instance, what drives social evolution or what qualifies as behavioral genetic change might be understood very differently in varied research contexts.)
