The fact that there is a sexual height dimorphism in humans–men are taller, on average, and women are shorter–is widely accepted. This is probably the least controversial dimorphism that exists and thus possibly, then, good and broadly acceptable evidence for (at least past) sexual selection pressures in human evolution. For these reasons, we read a few articles about human height dimorphisms for our meeting last week. We ended up focusing on physical reproductive pressures that could lead to this dimorphism–this was the specific pressure that came up in analysis on what specific pressure causes this trend. We recommend finding the articles listed below if you’re interested in this topic!
Some problems we had with the studies were:
1. we didn’t have the math background to judge the findings
2. we wished we had access to the actual data sets
