Because males of the species can mate more than once. They also do not suffer sudden onset of post-reproductive life while their other organ systems remain healthy for decades after like happens with human females.

Human men can reproduce pretty much up until death is why you wouldn’t include them.

because you can still technically have them. What’s up with conflating biology with society/culture?

That implies there was a selective pressure to develop a menopause and long post-reproductive stage in life for the females of the species, but not the males. It seems to be a relatively rare evolutionary trait.

That “if” doesn’t really count because they CAN if given the opportunity. Whether or not they have their last child around 40 doesn’t mean they can no longer have children. Like most other mammals they are still capable of reproducing until death. Human females however have a period of time in which they become…

Humans didn’t evolve with culture and society. That came second and the biological imperative of all animals is to first and foremost pass on their genes.

Great, you’ve completely missed the point of the study. I congratulate you.

That’s not their question at all. Take dogs as an example- female dogs and mice are able to have pups for pretty much their entire lives, although it becomes harder and litters are smaller as they age. Human females are fertile for a little over half their lives and undergo a menopause period that is relatively…

Men can still reproduce after the age of 45 though. In fact, men can reproduce almost up until death. Yes, their sperm may not be as fit and have a higher propensity for genetic aberrations but they can still reproduce. The same cannot be said for women after menopause and it’s a phenomenon worth studying as it is…

One reason could be that you’re taking up resources of those members of the population that are actively growing or propagating the species.

Maybe not until death, depending if they can still get an erection, but they have viable sperm until death.

Is there some sort of Promo code I can use for extra bones??

You mean people in New York don’t spend all their time split between their massive apartments and a coffee shop while seemingly never going to work?

King of the Jungle indeed

Except it isn’t just concussions that seem to be causing long term damage.

I don’t even think they invite Jeb. He just shows up.

Didn’t turn out so great for Betty though.

You mean besides the fact that we don’t really know if just playing college football is enough to get CTE? Or if just playing in High School is enough.

Didn’t the Browns shit all over NFL teams when they played against them before the merger?

There is the distinct possibility that you are a camel.
