Here's an interesting piece from the Economist The mismeasure of woman (a pun on a book from Stephen Jay Gould), which sheds light on many myths. One that caught my attention is:
Female is the default brain setting. Until the eighth week of gestation every human fetal brain looks female. The brain, like the rest of the human body, becomes male as a result of surges of testosterone—one during gestation and one shortly after birth.
On Why Do Beautiful Women Sometimes Marry Unattractive Men?, Dubner and Levitt talk about a new study by Satoshi Kanazawa, an evolutionary psychologist at the London School of Economics, suggesting that it may be a simple supply-and-demand issue: there are more beautiful women in the world
than there are handsome men.
This BBC report references a UK research suggesting that hungry men were attracted to heavier women and explains that how full a man's stomach is can dictate the type of woman he will fancy.
