The beauty of evolution is that it not only produces a wide variety of human offspring (via sexual reproduction and sexual selection) but also a _homo_ _sapien_ family unit in which each individual (male + female(s), usually) has different strengths. This surplus of skills has allowed humans to survive under a wide variety of circumstances and environments. Evolution does not guarantee long term survival of the fittest--it guarantees long term survival of the most adaptable. In some environments, the female may be more critical to the success of the family (or extended clan, or tribe, or what have you). In others, it's the man. Sometimes it's equal. But just because a particular skill set isn't the most valuable at any point in time doesn't mean that the individuals with those skills should be second class citizens. Eventually, years or decades or millennia from now, or thousands of miles away, their time will come again.
