Grandparents are a selective advantage well after reproduction. Older members of the tribe can watch the young while fitter members engage in hunting and foraging. They can also teach the young. Most tribes around the world that still exist you see this pattern.
- cthalupa 1y agoCorrelation is not causation. Plenty of people theorize there is large selective advantage here, sure. They may even be correct! Others disagree with them on it being a large advantage. But even if there is it doesn't mean that there is any reason whatsoever that increased GLP-1 production would be enough of an advantage to have had significant impact on evolution. We're going from A is true, B is likely true, C might maybe be true, all the way to Z is definitely true.
