How much meat did paleolithic humans really eat?
The paleolithic diet is usually presented as one which is based on meat and animal products. But this article proposes the possibility that paleolithic humans and their evolutionary ancestors might have had primarily herbivorous diets. Large amounts of grains are still out of the question, though.

The Diet of Paleolithic Humans
Stephanie Peske
December 19, 2001
Paleolithic vegetarianism, the idea that early humans were herbivores, rather than omnivores, has been debated for centuries all over the world. The diet of our early ancestors is a heavily-researched topic that raises several unanswered questions. Researchers have found evidence to support the idea of "subsisting or feeding on animal tissue" while other evidence has been found that indicates that herbivory was the diet of our early ancestors (http://www.webster.com/cgi-bin/dictionary). Despite studies that have shown our evolutionary links to the Paleolithic apes, Paleolithic eating habits are a matter of contention. Researchers explain, "Some data on this subject are available, but populations from which we can directly verify and expand the database are vanishing; this irreplaceable human resource needs to be utilized optimally while it still exists" (Eaton, Eaton III, and Konner, 1992). Through research and comparisons with the human’s close evolutionary relative, the chimpanzee, information has been found to support the theory that Paleolithic humans were vegetarians.
Ramapithecines were the earliest ancestors of humans (www.ivu.org/history/early/ancestors.html). They lived in subtropical forests that did not provide a year-round supply of food, so consequently they were forced to forage for plant life on the ground. It is also thought that they were vegetarians because of the abundance of wild grasses and cereals during that time period (about eight million years ago). The Austrapithecines, known as the Southern apes, succeeded the Ramapithecines about five million years ago. These were primates that, along with showing bipedalism (walking upright on two feet, a characteristic first seen in Ramapithecines), also developed the hunter-gatherer way of life ("a member of a culture in which food is obtained by hunting, fishing, and foraging rather than by agriculture or animal husbandry" (http://www.webster.com/cgi-bin/dictionary)).
The Austrapithecines used tools, but their skull was not quite humanlike yet (it was smaller, like an ape skull). It has been suggested that Austrapithecines, "developed bipedalism in order to reach fruits growing on small trees" (www.ivu.org/history/early/ancestors.html). This was believed to be true because the pelvis found in remains is very small, which would have provided good support for possibly standing upright to feed. The Austrapithecine Australopithecus ramidus dated back to 4.4 million years ago. In September of 1994, a skeleton was found from that era. The remains were found amongst Colobus monkeys and other tree-loving monkeys. Enamel covered the teeth of the human remains, suggesting that A. ramidus ate mainly vegetation (www.ivu.org/history/early/ancestors.html). About two millions years ago, the Paranthropus arrived. The massive teeth and jaw muscles on this primate indicate it had a diet of coarse plant material.
The next three primate descendants were Homo habilis, (1.6 million years ago), Homo erectus (half a million years ago), and Neanderthal Man (130,000 years ago). Scientists found that these three ancestors evolved into partial meat-eaters. These primate descendants ate a small range of lean meats, beginning by scavenging dead animals that had been previously killed and partially eaten by other creatures. There was a skeleton found from the Homo erectus era that had symptoms of hypervitaminosis (or an excess of Vitamin A), which is most likely caused by eating meat (www.ivu.org/history/early/ancestors.html). It is also thought that Homo habilis was the first omnivorous group of humans because "there is evidence of cut-marks on animal bones, as well as use of hammer stones to smash them for the marrow inside" ("Home Bases and early homonids," 1984). Forty thousand years ago Homo sapiens, modern humans, evolved. These modern hunter-gatherers have very similar eating patterns that resemble those of preagricultural human beings.
There has been evidence of the biological similarities between humans and chimpanzees. The DNA difference between gorillas, chimpanzees, and humans is less than one percent, less than between different species of horse (www.veg.ca/newsletr/novdec96/evolution.html). Dr. Katherine Milton, professor of anthropology at the University of California, has been studying these similarities. She discovered that the complexities of the food niche could have been a factor in increasing the longevity of primates, and that Homo sapiens were better equipped to solve dietary problems from changing environmental conditions. She also has found that dental patterns among fossils of early humans supports evidence of a high quality, plant-based diet, closely related to the ninety-four percent plant and fruit diet of chimpanzees. Finally, Milton’s studies have shown that the chimpanzee’s stomach is extremely similar to the efficiency of the human’s stomach to process fiber. "According to Milton, our digestive tract does not seem to be greatly modified from that of the common ancestor of apes and humans, which was undoubtedly a predominantly herbivorous animal" (www.veg.ca/newsletr.novdec96/evolution.html).
According to Dr. David Ryde, early humans are even more closely related socially and nutritionally to the Bonobo chimpanzee. Bonobo chimps have a high percentage of fruit in their diet (about eighty percent) and also consume fewer insects than the average ape. Bonobo chimps are not only similar to humans in their nutrition, but they are very similar in their sexual relationships. For example, when "arguments" occur between bonobos, sexual engagement afterwards may serve as a way to smooth the incident over and to re-establish normal relations again. These social similarities suggest that our ancestors and chimpanzees’ ancestors are similar, almost identical (www.beyondveg.com/nicholson-w/hb/hb-interview1c.shtml).
Paleolithic humans had some tools to hunt with, but they were not as useful as tools used by the modern hunter-gatherer. Professor Jared Diamond explains how the diet of early humans depended on their tools. He describes how he was invited on a hunt by a tribe in New Guinea that retained Stone Age "technology" and habits. Surprisingly, after an entire day of hunting, the tribe returned with only two baby birds, a few frogs, and mushrooms.
Although the men of the tribe frequently boasted of the large animals they had killed, when pressed for details, they admitted that large animals were killed only a few times in a hunter’s career. These peoples’ stone tools were far more advanced than the stone tools found on prehistoric sites, so Professor Diamond thinks it unlikely that prehistoric hunters could have enjoyed a much higher success rate than present day hunter-gatherer tribes (www.ivu.org/history/early/ancestors.html).
This suggests that since a modern hunter-gathering group was not very successful, then it was highly unlikely for our ancestors to be able catch even one large prey with their limited equipment.[b/ Like the New Guinea tribe, groups such as the Kalahari bushman and the Australian aborigines gather much of their food in the form of roots, fruit, nuts and other nutritious plant products. The proportions by weight of vegetable food and animal food in their diet compared with modern humans are about 81.3% vegetable and 18.7% animal (www.ivu.org/history/early/ancestors.html).
The energy and caloric intake requirements of preagricultural humans compared to modern humans vary considerably. Paleolithic humans were lean, robust, and needed a higher caloric intake than present humans. [b]Researchers explain, "Fruits, roots, legumes, nuts and other noncereals provided sixty-five to seventy-five percent of the average forager substance…which were generally consumed within hours of being gathered" (Eaton, Eaton III, Konner, 1992). These foods were often eaten uncooked; therefore, they still contained a high amount of vitamins and minerals. For some nutrients, the intake required for Paleolithic humans would have now only been received through vitamin supplements, such as folic acid.
The Intersalt Corporation Research Group did a study in 1988 on the Yanamamo and Xungo Amerindians and the Asaro from New Guinea. They found that these people are "relatively isolated, a little acculturated" (Eaton, Eaton III, Konner, 1992) groups whose food is free of any added sodium, "and their food is like that of hunter-gatherers" (Eaton, Eaton III, Konner, 1992). Their salt intake is a bout 256 milligrams compared to current Americans’ intake, which is about 1177 milligrams (Eaton, Eaton III, Konner, 1992).
Paleolithic intake consists of about double the amount of calcium, and more than three times the amount of carbohydrates than current humans ingest. The hunter-gatherers also had a wide variety of fruit and vegetables, often more than one hundred different varieties (Eaton, Eaton III, Konner, 1992).
There were no domesticated animals during the Stone Age. Because there were no tame animals, Paleolithic adults and older children had no way of attaining calcium, or any dairy products as do humans today. They received some dietary needs for dairy from plants such as coconuts and palm nuts, but they also received numerous amounts of nutrients because they ate the entire plant itself, shell and all (Eaton, Eaton III, Konner, 1992).
Two other features of Paleolithic nutrition that are different from modern human culture are fiber and protein. A preagricultural diet would have to consist of a moderately low protein and a high fiber intake for them to receive part of their daily dietary needs (Eaton, Eaton III, Konner, 1992). Scientists explain,
The numerous inconsistencies between current recommendations and retrojected Paleolithic nutrition suggest obvious investigative possibilities…. The most meaningful research designed to reconcile current nutritional recommendations with the nutrition that shaped our metabolic needs during evolutionary experience will probably involve comprehensive integration of multiple dietary variables and exercise activities in studies that begin early life and proceed through development into adulthood (Eaton, Eaton III, Konner, 1992).
In conclusion, there has been an extensive amount of research done on the topic of Paleolithic vegetarians. There also have been various theories about our early ancestors such as theories that the habitat of subtropical forests determined vegetarianism-like diet. Skeletal remains support this contention in both the Austrapithecines and the Austrapithecine Ramidus. Evidence suggests humans became carnivorous only within the Homo habilis, Homo erectus, and Neanderthal Man stages of evolution. Research also suggests that early humans’ diets are similar to those of the chimpanzee, which subsisted on a mostly plant-based diet. Anthropologists who study human tribes with Stone Age Technology and habits reveal that these humans eat mostly plants and small animals, and only rarely eat large prey. Finally, studies on Paleolithic humans suggest they existed on a moderately low protein and high fiber diet, furthering the argument that prehistoric humans were probably more herbivorous than carnivorous, though certainly this debate requires further research.

Humans adapted to eat a wide variety of foods. Saturated fat, grains, red meat, etc. We can thrive on almost anything.

MisterE,
We don't have the systems to detox plant toxins or extract substantial amounts of energy from plants.

Re: How much meat did paleolithic humans really eat?
Here's an interesting lecture from Teresa Steele from UC San Diego. Her contention, using both archeological and anthropological evidence suggest that modern humans brain size is the direct result of our ancestors moving from scavenging leftover meat from other animal's kill to becoming a hunter. We increased our meat protein intake.

LittleFighter,
Unlike MisterE, I never claimed that veganism is healthy. The article I posted suggests that we might better approximate the diets of our ancestors by including more raw, plant-based foods.
But since you seem to have already uncovered the mysteries of human evolution, biology, and health, maybe you shouldn't bother reading the things I post.

You're so right, really. I shouldn't bother. And don't get me wrong, I'm totally OK with people questioning dogmas, ideas, etc, I think it's truly necessary.
Some people don't like to have what they say questioned or challenged and don't reply with congruent and science backed ideas or they just ignore those who question them in a healthy way. That's very stupid in my opinion and dangerous for people;this happens everywhere.
I'm not saying that's your style. Maybe I shouldn't bother like you say, but if I don't bother, then I feel like I don't give a damn about the people on this forum and the fact they can be mislead. Maybe I shouldn't care at all...

Good article about Humans are Meat-Eaters or Veg.
Is meat-eating natural ?

Humans evolved the greatest hunting trait in existence..... a massive brain
Therefore, we thrive on meat

Re: How much meat did paleolithic humans really eat?
Based on my humble research, now I know that humans can thrive on different diets, like more meat and less plants, more plants and less meat, different ratios of macro nutrients, etc.
A common denomintator in healthy diets is the lack of crap, processed, artificial, toxic foods. Plants can be considered toxic, because they contain MANY types of toxins. Grains are the worst thing, specially because they have been altered. This doesn't mean that you can't eat plants, btw.
I respect those who are vegetarians, but based on my research, no single human group can thrive only on plant food, they NEED at least some amount of animal food to make it through.
I agree with abc123.
