There is a possibility that women become stronger, if man get lazy and women train more there could genetically surpass the avarage man in strength after some generations. For cultural reasons women were not meant to train their bodies in the past. But now they can and they are very ambitious.
The future holds genetic modification which will allow strength the be modified. While not likely, (because both males and females would be modified) it is certainly possible.
Of course evolution might bring strength more inline for the future when male and female differences are reduced, and perhaps bring females genetically stronger than men.
Again, not super likely, but definitely a possibility.
As the "no" statement said, men and women are equal in different ways. Men are stronger, women are smarter. That's how we were created or evolved, depending on how one looks at things. However, if one looks at things from a case-by-case basis, some women are stronger than some men. One example is that Ronda Rhousey can kick my a** in a fight for sure.
God made us the way we are for a reason. When we were hunter gatherers, men would hunt for food, while women would give birth for future families of hunters and more women. Sure, some women are stronger than men, but this is because they trained and worked out and stuff. These are acquired traits, acquired over that woman's life. These are not passed on. A really good karate dude might not have sons or daughters as strong and as physically fit as him.
The way this questions is worded is very loaded, because it is impossible to prove that this can't happen, so it should be an automatic 100% yes. However is it likely.
Basing on the history of mankind I would say no. For 250,000 years men have been physically stronger than women. However, it is very different in today's society, we have developed so much in the last 300 years. Men have genetics on their side, men produce more testosterone than woman, and I have never heard of a bodybuilder taking estrogen supplements. Men also currently have the edge in societal norms. Women are more attracted to physically strong men and men are more attracted to slender petite women. In short, although it is not impossible to disprove, the evidence would show that we would have to undue and reverse 250,000 years of evolution and societal development, and that is not likely.
There is no point in thinking that women can get any stronger than men, that is absurd. To begin with, we're born with certain characteristics according to the gender and the role we will have in nature. Women give birth; men, on the contrary, protect the family and hunt for food. So we need to be stronger, bigger, more agressive and intimidatory (that's why we have lower-pitched voices). As a consequence, nature makes us all men produce much more testosterone than women, a hormone that gives men all such powerful characteristics.
It's just genetic, we evolved for men to be the stronger, and that hasn't changed in the past few hundred years and I don't see it happening in the next few hundred either. Men being not be needed as much in the future, but the only way that would really change is genetic engineering.
This isn't to say that women aren't as flexible (because they're statistically more) or anything like that, and there certainly are some women stronger than most men, but in general, humans evolved with men having more PHYSICAL strength only. This is because when humans were evolving, when humans were hunter-gatherers the women were "encumbered" with pregnancy, therefore forcing men to be the hunters. We of course evolved, meaning that since men were the hunters, they had to evolve to be physically strong. This isn't to say that if humans were evolving in today's society this would happen, since we now don't need to worry about hunting considering how we've built up, but we can't change the way we evolved. In response to your argument about if all men suddenly got lazy, there is no reason for all men to get lazy and not women; both genders have equal brains and minds, so there is no reason for one gender to suddenly get lazy and not the other. Also, women did not evolve as strong not because of cultural reasons (as we didn't have culture in hunter-gatherer society) but for reasons stated above. Of course, none of this physical strength matters in today's society, therefore men and women are equal - this is just how humans evolved.
