Oh, at no point did I mean that either of those traits should be used as a measure of someone's pay and so on and so forth - to the contrary, what I meant was that we are different and we should embrace those differences rather than fear them - do read my posts above.The problem is, we can't use genetics to determine whether or not someone deserves the same amount of pay for the same job, or equal treatment in any aspect barring extreme cases. We have people who defy these norms quite often anymore, making them rather obsolete definitions. Hell, women fight to not be contained by genetic definitions, while employers are fighting to have access to the information for a myriad of hiring decisions. We can no longer compare ourselves to other animals either. We've effectively removed ourselves from the food chain, with only genetic links left to remind us that in some way, we're related to those other animals out there. You can say there's a reason the lioness goes out hunting (shopping) and the lion protects the territory (stronger, dominant, head of the house), but feminism already seeks to defy such basic definitions that are viewed as sexist, not just out of political correctness.
I mean, I understand what you're saying, but this is about feminism. Genetic links and animal gender relationships serve no purpose in the long run.
Quick Edit: Having actually taken a class on genetics as well, I can say with ease that things are still changing so rapidly in the field of genetics, old research being overturned, new things being found, that they're hard to use in a debate at all.
In nature, everything equals out. For example, women have aprox. 4% less brain cells then men, however those brain cells are more tightly connected with white matter than in the case of men who have more gray matter - communication between them is much faster. Women have a higher concentration of neurons in the frontal lobe - this is the area where decision-making and and problem-solving occurs. Men on the other hand have a higher concentration of neurons in the parietal cortex - the part of the brain involved in space perception. These and other differences in the brain cause various differences in actual, real life traits such as multitasking, abstract thinking and so on.
There's also the question of hormonal balance. In men, it is relatively static as we don't go through menstrual cycles. Changes in the hormonal balance in men occur slowly but gradually with age. With women it's a whole different story - the hormonal balance skyrockets and plummets all the time during the menstrual cycle and only once it stops does the situation normalize. This hormonal balance, or lack of thereof in some cases can lead to mood swings - they do not affect everyone but they do occur.
What I'm saying is that, to an extent, we are naturally talented in different areas and our behavior is, to an extent, dependant on our bodies. Since we are human, we can deliberately choose to train ourselves in areas that are not necessarily our forte and that's a great thing. We can choose to be a man in a feminine role of a "mother", we can choose to be a woman "breadwinner" and in some rare cases we may actually be born into those roles as well by a stroke of the genetic wand.
We should all be treated equally, but at the same time we should be mindful of the differences between us when dealing with each other. True equality doesn't mean that everyone gets the same ladder to get over a fence regardless of how tall we are - true equality means that everybody gets a ladder that fits him or her so that everybody gets over the fence.
