I don't know much about evolution, but what I do know is that environment and not just environment but behavior and actions play a role in how a species evolves correct? If this is true why wouldn't women and men 200,000 years from now be different than they are today because women are doing more manly things and men are doing more girly things. I mean certainly this will impact us in a way we may not necessarily want.
I don't entirely agree, but I'll run with it.
In that respect, it doesn't really matter. It's not like we men are still responsible for going on hunts to capture and kill dangerous predators for food, while being at risk of becoming the food of some other dangerous predator. We no longer have to go floor a mammoth to survive the winter.
Most of us these days, in the west at least, sit behind a computer all day.
And those of us who still do heavy lifting "men's work", like farming or manually (un)loading ships and stuff carrying bags upwards of 20kg... they still have an easier life then our ancestors did 100.000 years ago.
In our modern society, there is no longer a need for such daily activities. I'ld also guess that that is one of the prime reasons why the classical gender roles change. Society evolves and a lot of the jobs can be done by both men and women. Some jobs are done better by women and other jobs are done better by men, perhaps. But by and large, the majority of jobs can be done by both - without any need for physical changes or whatever.
Could it be that there will be physical change due to evolution? Well, yes... it's not like evolution as a process stops. It's not like you can resist it....
But more importantly, the idea of "
...we may not necessarily want", makes little sense to me. We are talking about gradual change that will/might happen over many generations.
None of us currently alive will witness that. And the people who grow up in that world... it will simply be their reality. "
i don't want this" is not what they will be saying. For them, that "new" reality will be normal.
