Not everyone has children. Even more don't have any surviving grandchildren.
This is true even today, but back in the original "state of nature", death for all sorts of reasons was way more common than today.
Run that through a few thousand generations, with wars, genocides and epidemics, and you get big numbers.
- deepsun 1y agoYes, but people had way more children. E.g my grand-grandparents had many kids, and counting only surviving ones is still 3x more than my grandparents. Combined with much earlier parenthood, humans were "diffusing" their genes way faster than we do before dying earlier.
