Then in 2023 DeSilva revised his argument in (link above, in the description), extending the date back, still not giving anwers about the shrinkage observed since 100.000 years ago.

yeah, from the last 3,000 to within the last 10,000 years, with the sharp decline ~5,000 years ago... which does line up with widespread adoption of agriculture still.

Of course you can choose to believe what you want.

The point I was trying to make is that there is no scientific consensus on the topic about how global the decline was, when it began and why it happened - as well as if it is related to the formation of complex societies, farming, language, dietary changes, temperature, or body size.

there is no scientific consensus on the topic

Agreed. That is why we are here speculating.

when it began and why it happened

This is what makes it a super interesting topic!
