Has anyone checked to see if it's happening to animals too?
It's happening to dogs as well, apparently: https://news.ycombinator.com/item?id=14857588

For a gene to decay without selective pressure takes a very long time, especially when your population is not on the edge of starvation.
A selective pressure going away is as strong as a selective pressure appearing. Eg. 100 years ago, 20% of children would die as infants. Imagine all of those children died of a mutation which causes half the usual sperm count, together with a lack of resistance to polio/cholora. Now that polio/cholora don't exist, all those people survive, and within 3 generations, nearly everyone has at least a grandparent with that…

That wouldn't be a steady state. A gene that powerfully negative, with no upsides, would decrease in prevalence by a significant amount every generation.

Everyone has an ancestor with the gene. But they only have a 1/8, 1/16, 1/32 chance of inheriting it from that specific ancestor. Generation to generation, the percentage of people with the gene will be almost identical. Just like eye and hair color.

#153The chart of sperm count vs plastic production is pure BS. It shows nothing but a lack of journalistic integrity.
would you mind expanding?

#154What's some actionable advice about how to increase your T? If you google it you just find snake oil bullshit.

> followed by the bit about men becoming less male. This is pretty obvious without any research (papers). The difference between my generation and our children is already staggering in this regard. Not sure if that's just change in culture or physiological though; maybe a bit of both?

Yeah , this is about a particular trait that is not in either of the linked articles though. You took what I said out of context which makes it a platitude.
