When and why did humans lose the ability to eat raw meat?

Question

As humans evolved, why did we come to depend on fire to eat meat?

Answer 1

We never lost the ability to eat raw meat (in fact, people eat it constantly). The problem with raw meat is two-fold: 1) it contains organisms that could kill you and 2) it's hard to digest, with a lot of proteins that make it hard to pass through (if you know what I mean).

When man (by fortuitous accident) cooked meat (just by leaving it too close to a fire source, really), they were removing possible diseases from their body and increasing their nutrition. You can see it in the fossil record - Australopithecines had large flat teeth that were used for chewing (constantly). They needed to because nothing was cooked, and too rough to digest without constant mastication before swallowing. However, Homo erectus, who used fire and, likely, cooking, had much smaller teeth but a much larger body. They were getting more nutrients from their food, with much less wear and tear - they no longer had to constantly forage - meat and plants alone gave them better sustainence when cooked!

This shift eventually brought about the massive increase in size and cranial capacity that brought about Homo sapiens.

Answer 2

We can still eat raw meat, it's just that sophisticated people (probably women) decided it was gross!! Actually I've heard that eating raw organic meat is better for you.


PS Humans didn't evolve!!

Answer 3

We probably could, but it would cost us millions of lives. We just need to build up resistence to the bacteria and stuff that grows on it. Some cultures do eat raw meat, and they are fine.

Answer 4

I eat uncooked meat 3-4 nights a week, at the same time with wild beef and grass fed red meat, oysters, fish, sheep, hen and eggs. surely I eat all of my nutrition uncooked and that i by no skill fall unwell. I eat instinctively and prefer it, will by no skill bypass lower back to cooked. Been ingesting it uncooked for 2 years and recognize a lot of alternative individuals who do. I eat purely the superb high quality and assume you need to (in all likelihood may) fall unwell from ingesting and unwell animal, eg. farm raised and fed antibiotics and hormones and ate up grains. by skill of ways more suitable micro organism at the same time with salmonella is chanced on on vegetables than meat.

you can eat raw meat. But you cant leave it out or eat raw meat after you put it in the fridge. If you kill an animal, you can eat its meat right there after you killed it.

Answer 7

Probably when they were able to deduce through logic and reasoning that raw meat can carry bacteria and other nasty things that tend to make you sick (or worse).

Besides, once you go BBQ, you never go back!

Answer 8

Hasn't happened -- we can eat raw meat. (Consider steak tartare.) But there are reasons for cooking it:
- Kills bacteria
- Improves taste
- Makes it more chewable.

Answer 9

We cooked meat because it was easier to chew and digest.Less grain chewing to get the protein we needed.We developed smaller jaw muscles.Which we grew bigger brain cavities.The more gray matter the smarter we got.Well maybe not all of us....jk.
