Sure. If you’re a hunter, you’re not going to kill squirrels every day to provide meat. You’re going to try to bag something more substantial, something for the whole band. So it stands to reason that the ancients might not have eaten meat everyday.
Scholars now are claiming that the view of men as hunters and women as gatherers isn’t accurate and that women were also hunters, but I bet that if they really did unbiased research they’d find out (and publicize) that men were also gatherers, and perhaps even that men did more gathering than women did hunting.
Yeah, it’s agenda-driven fake science, IMHO. It’s not unlikely that soups and stews (meat/fish/veggies) were the primary nutrition source for early groups.
