The same way humans do today.. It just took a lot longer to digest and they had to sleep more. Cooking food was one of the great jumps in the evolution of man. It allowed them to digest food more easily and spend more time doing things that advanced us.
Early humans had a significantly larger gut than modern humans. Monkeys, apes, and other primates have a larger gut in proportion to body size in order to digest raw food. Early hominids learned to control fire and began cooking our food more than 2 million years ago. Control of fire and cooking food enabled evolutionary changes such as reduction in mouth size, reduction of gut size, loss of hair, and large brains because of extra energy availability. A really good scholarly book on this topic is called "Catching Fire: How Cooking Made Us Human." Not to be confused with the Hunger games book of the similar name.
Check it on Amazon. It will give you both books.
They didn't live nearly as long as we do now. Plus, not quite as many strains of illnesses out there back then. That may have helped them.
Steak tartare is eaten today and my dad ate his steaks rare which for him was passing it over the flame.
You would be surprised at the things you will eat when you are starving.
with their mouths.... ;) lol
Actually it is believed that this is one of the reasons they had a very short life expectancy.
The first human beings are the ones who invented "Fire"!
You can eat many raw meats with low risk especially if they are fresh and you know the animal is healthy.
They didn't know any better
They were able to do this because they did it. If man had never started cooking the meat we would still be able to eat it raw but because we cooked it we no longer had a need to build immunitys to the germs.
There is circumstantial evidence that our tree triumphed because our ancestors cooked their meat while the larger and stronger breed didn't. It united us and protected us.
Not sure where the branch was. I do know the breed that didn't last was Neanderthal.
Not if it's fresh...I think it's safe to assume that they had much stronger immune systems
As I look at my answer, I mean to say that they were probably more immune to bacterias and parasites
Yes, it has a lot of germs. They eat it and if they survive...well good for them! That's why the population did not flourish. Most of them just died due to stupidity. =P
They only ate happy cows and sushi
Back then, humans had stronger immune systems and larger guts. We were able to digest food better. Now today our immune systems are more suppressed due to society. We also cook our food so now our bodies don't use as much energy for digestion and is no longer used to doing so much work and the gut is smaller.
