Yeah, it's not their ovaries running out of eggs or anything like that... clearly men are the force for negative occurances here.

I think what they meant was male primate's tendency to choose younger mates and ignore the older ones meant that we evolved less eggs because there was no evolutionary advantage to being fertile in old age. Menopause is actually pretty damn rare in the animal kingdom, it seems to be scattered randomly around the evolutionary tree.
Although it is misleading to call them 'men' as this would have occurred waay before we were really able to call ourselves human.

Also women didn't tend to live into their 50s as recently as 3-500 years ago, which is too short a time for any major evolutionary shift to take place. But why would they pay attention to basic evolutionary biology in a study that's supposed to be about the evolution of a biological process? That would run counter to their misandrist viewpoint.

Life expectancy in the past is skewed by high infant and child mortality rates. At birth you were roughly expected to live to about 30 years, but if you made it past puberty (about 20) you could expect to live past 55 years as far back as 10-20,000 years ago (which is pretty much as far back as we can currently study with any accuracy, before that skeletons in large numbers to compare are rare), and if a woman made it through so many child births she could expect to live even longer, given the risk to her personal safety being quite low.
The short life span of our ancestors didn't develop until humans began using agriculture and were then able to sustain much larger groups with the food surplus, making wars more sustainable, eradicated the need to adopt members of defeated tribes to make up numbers and leading to a 'take no prisoners' attitude that was so popular for most of early human civilization.

TLDNR the short lifespans of our ancestors were mostly brought on by the environments in civilizations, before that we were quite a long lived species and many women would have made it past menopause.

I think you are severely underestimating the effect modern medical technology has had on lifespans, furthermore, there is no evidence to suggest that menopause hasn't been around since before agriculture, in fact it is incredibly unlikely that anything else could be the case.  That being said, there is no evidence in the fossil record to indicate pre-civilized women having life spans exceeding even the mid-20s, so I'm going to have to call bullshit barring some anthropological evidence supporting your assertion.
