Problem: Determine the effect of female promiscuity and mating system on brain size, doing the best you can to control for lack of independence due to shared evolutionary history. The data come from Scott Pitnick, Kate E. Jones, and Gerald S. Wilkinson. Mating System and Brain Size in Bats. Proceedings: Biological Sciences 273:719-724.
