As a result of high levels of male parental investment, humans evolved into a somewhat “androgynous” species - a species in which human females exhib… - Steve Stewart-Williams

Changes in the inhabitants of the earth do not reflect a constant process of improvement in the design of organisms, any more than changes in fashion over the years reflect a constant process of improvement in the quality of clothing.

A similar analysis applies within the realm of mate preferences. Several commentators pointed out that sex differences in human mate preferences are generally quite small... As such, the central claim in EP [evolutionary psychology] should probably be "Human beings evolved to put a fair amount of weight on good looks in a mate" rather than "Men evolved to put more weight on good looks than women." Again, the latter statement is true but potentially misleading. This sounds like a contradiction, but it is not; the statement is misleading if it is given undue weight.

Think about some of the highest status men in modern societies: sports stars, rock stars, politicians. At first glance, it might seem that these individuals provide further proof of men’s polygynous nature: They are often notorious for their sexual antics and infidelities (the famous scandal with Tiger Woods is a case in point)... However, the picture is not so simple. Many of these men are in the position where they have essentially an unlimited supply of potential sexual partners. Do all of them or even most of them eschew long-term relationships and opt instead for as many one-night stands and brief love affairs as possible? Sometimes, perhaps, but often they do not. These men — the most eligible bachelors, the highest status males in our species — often do what male chimpanzees never do: They fall in love and form long-term pair bonds.
