Here an interview with Satoshi Kanazawa, one of the authors of Why Beautiful People Have More Daughters, an introduction to evolutionary psychology.

SK: In fact, we’re not playing catch up; we’re stuck. For any evolutionary change to take place, the environment has to remain more or less constant for many generations, so that evolution can select the traits that are adaptive and eliminate those that are not. When the environment undergoes rapid change within the space of a generation or two, as it has been for the last couple of millennia, if not more, then evolution can’t happen because nature can’t determine which traits to select and which to eliminate. So they remain at a standstill. Our brain (and the rest of our body) are essentially frozen in time — stuck in the Stone Age.
