“Wilma! Where’s that brontosaurus stew you promised?”
The tendency for "experts" to have such low opinions of our ancestors', 30 or 40 thousand years past, native intelligence and ingenuity is frustrating. Considering the conditions in which they were surviving, to the point of success where they were able to raise offspring from whom we are all descended, they were no less and probably quite a bit brighter than 99% of all modern day PhD's.
“...so that they could have avoided death by protein poisoning.
“The kidneys and liver are limited in how much protein they can process in a day when more than that amount is consumed, ammonia or urea levels in the blood can increase, leading to headaches, fatigue and even death. So humans must get more than half their calories from fat and carbohydrates.”
Geez, these people are ill-informed about nutrition.
Protein poisoning is almost exclusively confined to those who just eat rabbit, one of the leanest meats, to the exclusion of fats from any other animals, *or* carbohydrates.
You can eat a heck of a lot of protein as long as you have a substantial amount of fat as well. With just a little carbohydrate with some food vitamins every couple of weeks. The end result will be a lean body frame with adequate fat to support the immune system. A “walking/running hunter’s” body.
Importantly, human parasites were a big part of the equation as well in ancient times, as they reduced the available nutrition to the body.
Only recently have calculations been made as to the nutritional difference between raw and cooked foods, and it was discovered that cooking food is very important, as it radically reduces the *amount* of food that needs to be consumed. If all you consume is raw food, even consuming much more, you will still likely develop some form of malnutrition.
It is thus very likely that when humans began to consume cooked food, it resulted in a population explosion and cultural advance.
As long as you keep the fire below the water line you can boil water in almost any type of container, including a paper one.
