Early humans were eating meat over a million years ago and possibly as far back as 2.6 million years go.
Yeah but they died out.If they died out.........we wouldn't 't be here.......... sigh.........
The term "hominid" is also used in the more restricted sense as hominins or "humans and relatives of humans closer than chimpanzees".[2]
In this usage, all hominid species other than Homo sapiens are extinct.
A number of known extinct genera are grouped with humans in the Homininae subfamily, others with orangutans in the Ponginae subfamily.
The primatological term hominid is easily confused with a number of very similar words:
- A hominoid, commonly called an ape, is a member of the superfamily Hominoidea: extant members are the lesser apes (gibbons) and great apes.
- A hominine is a member of the subfamily Homininae: gorillas, chimpanzees, bonobos and humans (excludes orangutans).
- A hominin is a member of the tribe Hominini: modern humans and their extinct relatives.
- A human is a member of the genus Homo, of which Homo sapiens is the only extant species, and within that Homo sapiens sapiens is the only surviving subspecies.
Homo sapiens (Latin: "wise man") is the scientific name for the human species. Homo is the human genus, which also includes Neanderthals and many other extinct species of hominid;
H. sapiens is the only surviving species of the genus Homo.
Modern humans are the subspecies Homo sapiens sapiens, which differentiates them from what has been argued to be their direct ancestor, Homo sapiens idaltu.
Anatomically modern humans first appear in the fossil record in Africa about 195,000 years ago, and studies of molecular biology give evidence that the approximate time of divergence from the common ancestor of all modern human populations was 200,000 years ago.
Ok but the question is, did humans eat meat back then?
Yes of course they did. You eat pretty much anything to survive. Bugs, snails, whatever you can catch or kill. Ask Bear Grylls. There would have been long periods in earth's history where it would have been difficult to grow food or harvest it from nature.
The point is, humans are not naturally meat eaters and can survive, even thrive on a vegetarian diet.
Humans can also manage the ingestion and digestion of meat quite well but cannot live exclusively on meat without serious health issues such as bowel and heart disease.
By all means enjoy a good hearty steak or roast (I do) but don't kid youself that a diet high in animal products is good for you.
A good barbeque is appropriate for today's ANZAC day holiday, I think, pity it's raining.
Human evolution
This article is about the divergence of Homo saapiens from other species.
For a complete timeline of human evolution, see Timeline of human evolution. For other uses, see Human evolution (disambiguation)."Evolution of Man" redirects here. For the album by Example, see The Evolution of Man.Human evolution is the evolutionary process leading up to the appearance of modern humans. While it began with the last common ancestor of all life, the topic usually covers only the evolutionary history of primates, in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of hominids (or "great apes").
The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, ethology, linguistics, evolutionary psychology, embryology and genetics.[1]Genetic studies show that primates diverged from other mammals about 85 million years ago in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around55 million years ago.[2] The family Hominidae diverged from the Hylobatidae (Gibbon) family 15-20 million years ago, and around 14 million years ago, the Ponginae (orangutans), diverged from the Hominidae family.[3] Bipedalism is the basic adaption of the Hominin line, and the earliest bipedal Hominin is considered to be either Sahelanthropus or Orrorin, with Ardipithecus, a full bipedal, coming somewhat later. The gorilla and chimpanzee diverged around the same time, about 4-6 million years ago, and either Sahelanthropus or Orrorin may be our last shared ancestor with them. The early bipedals eventually evolved into the australopithecines and later the genus Homo.
Consider what evolution means Icy.....lol.
no argument from me on this point siggie...lol
after millennia, humans have still not evolved to carnivores, though.

Because it is nutritious, and DELICIOUS.
Indeed it is Podds
However our current massive consumption involving the deportation and slaughter of huge herds of cattle and sheep is way out of proportion to our need of meat and indeed is making us very sick.
5 Negative High Protein Diet Effects
1) A High Protein Diet Increases Your Risk Of Osteoporosis
Research shows that women who eat high protein diets based on meat have a higher rate of bone density loss than those who don't. Women who eat meat lose an average of 35% of their bone density by age 65, while women who don't eat meat lose an average of 18%. In the long run, bone density loss leads to osteoporosis.
2) A High Protein Diet Puts Strain On Your Kidneys
It's well known that patients with kidney problems suffer from eating a high protein diet. While dieters with normal, healthy kidney function don't seem to suffer any ill effects from eating a high protein diet, such a diet can put strain on your kidneys. Your kidneys are responsible for filtering a number of substances, including protein, from your blood. So a high protein diet can put strain on your kidneys; those with reduced kidney function should avoid such a diet.
3) High Protein Diets May Contribute to Cancer
Some studies show that high protein diets may contribute to the development of some cancers. People who eat low protein diets have been shown to have low blood levels of Insulin-like Growth Factor-1 (IGF-1). High protein diets increase blood levels of IGF-1, which some researches believe may contribute to certain forms of cancer.
4) High Protein Diets Can Cause Damage to Internal Organs
Your body needs carbohydrates to make energy. When you deprive your body of carbohydrates, it's forced to burn body and dietary fat and protein to make energy instead. When your body begins to burn large amounts of body fat, ketones can accumulate in the body. When dangerous levels of ketones accumulate in the body, the dieter could succumb to a diabetic coma, which could be deadly without immediate treatment.
Even if ketones don't accumulate to dangerous levels, you could suffer damage to the internal organs as your body burns the protein in the tissues of your heart, liver and kidneys for energy. Damage to the organs could lead, eventually, to organ failure.
5) High Protein Diets Cause Nutritional Deficiencies
Perhaps one of the most common risks of high protein diets is nutritional deficiency. Fruits and vegetables are necessary to a healthy diet, because they provide the vitamins and minerals your body needs. Cutting out whole grains eliminates dietary fiber and increases your risk of vitamin E and B deficiency, as well as irritable bowel syndrome and, in the long run, colon cancer.
It's always wise to exercise moderation in all things. By all means enjoy your steak, snags and roasts, but don't have them more than 2-3 times a week.
And don't kid yourself that you're a carnivore that's meant and designed to eat meat.
