Why are humans biologically and psychologically the way we are?

I'm not writing about culture or religion here so it is obvious then I'm writing about Anthropology and natural selection.

I was thinking today about this. I mentioned to a dental assistant today how men only have a dental floss size of connectors between their right and left brain whereas women have a pencil size bundle of connective neurons going from the right and left brain and back.

Why is this? It is because in order to kill or be killed while protecting your family, your loved ones, and your wife and children it is much easier to do this if you have less connnections between your left and right brain. You have to be able to go robotic and kill with efficiency and with a bigger intuitive connection between your left and right brain you might not succeed in this. Also, you might have a 50-50 chance of dying in these situations so having the capacity to go robotic and efficient even if you die is extremely important to everyone's survival in your family, group, tribe or nation.

Conversely, women are biologically predisposed to looking for a single quality man to have children with. So, they are looking for quality over quantity. And a man is just the opposite with his primary biological function being to impregnate as many women as possible. However, women in general often get very upset about this difference between the biological imperatives between men and women. Men don't get upset about this at all unless their wife or girlfriend does (or their mother or female friends).

So, there you have it in a nutshell. Men and boys have had to sacrifice their lives for their families ever since humans began on earth in any form. Conversely, women have had to protect their children from harm by staying alive long enough for those children to either grow up or somehow fend for themselves.

Men who bred before war or accident or illness struck them down and who impregnated women who got their children to adulthood (or at least until they could grow enough to breed and reproduce too) are the genetics of us all today. Only those smart enough or lucky enough to do all these things had their genetics passed down to us.

So, this is who we all are today biologically and natural selection wise speaking today.

However, now if you add culture, sociology, philosophy, religion on top of this you then get people in specific cultures around the world and who they are on top of their natural predispositions caused by 100s of thousands of years of human survival and evolution.

Also, if we add to this mix men being attracted to wide hipped taller stronger women with bigger breasts this is because with wider hips a child might be successfully born in the olden days without a caesarian. Because up to about 1900 as many women died in childbirth as men died from accidents and wars. So, it is one of the ways populations stayed pretty low on earth until 1900 or so.

So, one of the primary reasons for overpopulation now on earth is that women stopped dying so much in childbirth when Caesarian sections became more common here on earth. For example, it is about 30% to 40% of all births likely on average now that are Caesarian sections.

This also will create a lot more kids being born and surviving that wouldn't have before and also will tend to increase the size of heads of kids worldwide and also will tend to increase the size of people worldwide because bigger babies often were not born because they got stuck in the birth canal of women too small in the hips to bear them and often the women died too.

So, possible 30 to 40% of the births now would have resulted in the deaths of both the mothers and the children in the past. So, if you take those births and start multiplying worldwide you see why there will be 9 billion people on earth by 2050.

Since the world likely cannot (at least now) feed, cloth or have enough fresh water or homes for them to grow up in or schools to educate them by 2050 it won't be 10 million children and adults dying before age 50 like now from accidents, illness and all other causes per year, it will be 20 to 50 million people dying likely from weather (global climate change), wars (caused mostly by overpopulation) and bad water (mostly caused by human and animal feces that gets into the water supplies of the world which causes dysentery, giardhia, Cryptosporidium etc.

Anyway, I sort of went all over the place with this article. However, all this is important information for mankind to understand to help solve the problems of the human race this century and beyond so we still might be around in some form as human beings (whatever that will be then) 1,000,000 years from now on earth on whatever planets or dimensions we live on or in then.
