I watched this interesting show on how the Kalahari bushmen hunt:
https://www.youtube.com/watch?v=q7fePoqb3Sk
They have likely been living in a similar way for the last 60,000 years. These bushmen don't waste any part of the animal. At 13:37 a 60+ yr old yet very healthy bushman hands the presenter a piece of liver and tells him it is good for him.
Perhaps tolerance for Vitamin A is largely genetically determined? Note how the presenter's taste buds tell him it is disgusting yet the bushmen think liver tastes good.
Perhaps it is just other chemicals interfering with Vitamin A in industrialized countries? Perhaps the bushmen lose a lot more VA due to sun exposure, smoke exposure, parasites, exercise etc? Perhaps their diet allows easier elimination of excess VA?

They aren’t exposed to formaldehyde that competes for detox. They aren’t exposed to glyphosate that does damage in many ways. They don’t take supplements that inadvertently block detox. They don’t take medications etc etc...

How much liver to you think these bushmen consume? Of course we have adapted to be able to consume vitamin A. But not an overabundance. I would bet if you added up how much liver they actually eat you would find it is not that much. There is evidence of vitamin A toxicity dating back a long, long time in the archaeological record. I think people lose sight of the fact that the "detox" diet is a diet to remove oneself from a toxic state. It is not necessary for avoiding toxicity. But one step at a time. First detox, then establish a balance that feels right for you.
But yes of course on top of that a lot of it has to do with blocked detox pathways, no doubt about that.

They have access to a lot of liver although I don't know whether they eat all of it. It takes a lot of energy and time for them to hunt so I doubt much of the carcass is wasted.
Watching the whole series with different tribes around the world gave me the impression that they mostly eat starch and meat. Some of their starches are low carotene, some are high. Papua New Guineans consume large amounts of sweet potato so they will be getting a very high carotenoid intake. The tribes don't seem to eat a lot of greens or non starchy vegetables. When reading more about the bushmen they apparently eat a variety of nuts, tubers and fruits, I didn't see any veges on the list of primary foods.
We have one study postulating that an ancient hominid's bone deformation was caused by hypervitaminosis A, it is definitely not certain. I think it is likely though.
