Insect food is the predominant animal matter resource for primates. Primate diets tend to be highly variable in, Humans are very similar to anthropoid apes, which is established via a comparative anatomy/, The Gombe Preserve is small, and surrounded by human-. Through environmental reconstruction of the areas ancient humans lived, inferences of available resources can be made. This gives us more time to go about other activities throughout the day. Regarding chimpanzee predation, Teleki [1981, p. 305] reports that: Over and above the reality that predation and meat-eating by chimps is widespread, the claim that chimps do so in imitation of humans or baboons is both unproven and dubious. Extreme diets--diets that are 100% of a specific food or narrow food category--are not very common in nature. For photos of a wild orangutan eating insects, see Knott [1998], p. 42; and for a photo of a wild orangutan eating a vertebrate--a rare event--see Knott [1998], p. 54. Return to beginning of article We did not find robust sex-specific differences in human or chimpanzee RBC plasmalogen levels or composition. Note that some experts use a different, more precise definition for the term omnivore, and disagree that mammals are omnivores--instead they suggest using the term faunivore for animals that regularly include fauna (other animals) in their diet. GO TO PART 5 - Limitations on Comparative Dietary Proofs [25] Humans and other apes occasionally eat other primates. Over and above the reality that predation and meat-eating by chimps is widespread, the claim that chimps do so in imitation of humans or baboons is both unproven and dubious. GO TO PART 6 - What Comparative Anatomy Does and Doesn't Tell Us about Human Diet Because dietary classifications are not strict in nature, a frugivore might deliberately eat some animal foods, hence not qualify as "vegetarian" as the term applies in human culture (similar remarks apply to folivores). Note in the above remark that predation by chimps has been found at all major study sites, although it is possible that some groups of chimps hunt rarely, or not at all. As this article shows, diversity rather than specialization is typical of primate diets. At the same time, the diet that most cultures eat today is dangerous to our health and the health of our planet. SEE TABLE OF CONTENTS FOR: As Teleki points out (1975: 127ff. Its earliest meaning was generally of any non-human anthropoid primate, [3] Modern biologists and primatologists refer to apes that are not human as "non-human" apes. He placed the three genera Homo, Simia and Lemur in the order of Primates. Modern taxonomy aims for the use of monophyletic groups for taxonomic classification;[12][f] Additionally, recent research has uncovered that Neanderthals once thought to be strict carnivores are now thought to have incorporated more plants in their diets (even possibly cooking vegetables). Of further interest here is the information that termites are known to contain significant quantities of vitamin B-12; see Wakayama et al. However, as knowledge of the actual diet of wild primates/anthropoid apes (from field observation studies) increases, the reality that most primates/apes include some animal foods (even if only insects) in their normal, natural diet is becoming better known. †Dendropithecidae In general, dietary classifications in nature are not as distinct/clear as the narrow, simplistic, precisely defined diets promoted by certain dietary advocates. [26] Some of these primates are now close to extinction with habitat loss being the underlying cause. M.W. Hence, since most readers would generally understand that the phrase "apes are NOT vegans" means that a human who eats the same diet as the apes would not qualify as a vegan, here we won't worry about the technical terms unless/until they are necessary to assist the reader in understanding the material. So "ape"—not to be confused with "great ape"—now becomes another word for hominoid including humans.[3][d]. Request full … The booklet argues that: This alone suggests that sufficient time has elapsed, in evolutionary terms, for chimps to adapt to such allegedly "imitation" behavior. Chimp/Baboon Interaction. Humans are very similar to anthropoid apes, which is established via a comparative anatomy/physiology table (pp. [24] Other food production and processing methods including animal husbandry and industrial refining and processing have further changed human diets. Other writers (elsewhere, not in FFH) suggest that chimps eat meat in imitation of baboons. These studies have shown that in their natural environments, the non-human hominoids show sharply varying social structure: gibbons are monogamous, territorial pair-bonders, orangutans are solitary, gorillas live in small troops with a single adult male leader, while chimpanzees live in larger troops with bonobos exhibiting promiscuous sexual behaviour. Thus, omnivorous primates are mainly frugivorous and, depending upon body size, obtain most of their protein from insects and leaves. The structural problems in the above type of argument are addressed in later sections. Moreover, predatory behavior involving vertebrate prey has now been recorded at all major study sites in equatorial Africa, from Uganda and Tanzania to Sierra Leone and Senegal. Another relevant aspect of dietary classifications: The terms vegan, fruitarian, and vegetarian are all human cultural terms, and are used, at least by most dietary advocates, with narrow definitions. Further, there is even some academic disagreement over the definition and use of the term "omnivore." ("FFH" is used as an abbreviation for Fit Food for Humanity in the material below.). For this reason all attempts at transplants from apes or baboons to man have been disastrous failures. First, we have to look at the digestive system of the great apes, which include gorillas, chimpanzees, orangutangs and bonobos. PART 1 PART 2 PART 3 PART 4 PART 5 PART 6 PART 7 PART 8 PART 9 Ape Diets. Many characteristics of modern primates, including our own species, derive from an early ancestor's practice of taking most of its food from the tropical canopy Ape diets, with emphasis on chimpanzees, are summarized in the article "Setting the Scientific Record Straight on Humanity's Evolutionary Prehistoric Diet and Ape Diets" on this site. GO TO NEXT PART OF ARTICLE This section will focus specifically on the issue of ape diets. [33], This article is about the branch of primates which includes humans. A comparison of humans vs. allegedly "vegetarian" anthropoid apes is frequently a part of comparative anatomy/physiology "proofs" that assert humans are natural vegetarians. GO TO PART 9 - Conclusions: The End, or The Beginning of a New Approach to Your Diet? Human diets are sometimes substantially different from that of other apes due in part to the development of technology and a wide range of habitation. Why Humans Outlive Apes. SEE TABLE OF CONTENTS FOR: Chimpanzees, on the other hand, spend a remarkable amount of time, mental effort and tool use on searching out insects and feeding on them in every place where they have been intensively studied. Major studies of behaviour in the field were completed on the three better-known "great apes", for example by Jane Goodall, Dian Fossey and Birute Galdikas. The superfamily Hominoidea falls within the parvorder Catarrhini, which also includes the Old World monkeys of Africa and Eurasia. See below, History of hominoid taxonomy, for a discussion of changes in scientific classification and terminology regarding hominoids. Insects are eaten by all extant apes, i.e., chimpanzees (e.g., Lawick-Goodall 1968), orang-utans (Gladikas-Brindamour1), gorillas (Fossey2), gibbons (Chivers 1972, R.L. ), such terms are first used as shorthand references to a particular dietary specialization but then gradually become inclusive descriptions of an animal's entire diet. Note: The above quote is included to specifically inform readers that there is no evidence that predation by chimps is a "new" behavior, and that there is extensive, complex, baboon/chimp interaction. REPLY/COMMENTS: Both lowland and mountain gorillas consume insects, deliberately and indirectly, that is, on the vegetation they consume. Thus, omnivorous primates are mainly frugivorous and, depending upon body size, obtain most of their protein from insects and leaves. †Proconsulidae Galdikas and Teleki [1981] report that orangutans at Tanjung Puting Reserve in Indonesia consumed 4% fauna (insects, eggs, meat) by feeding time. The diet was plant based, like the diet eaten by apes, who genetically are our closest relatives. The above quote from Hamilton and Busse [1978] cites Fossey (personal communication) regarding insect consumption by mountain gorillas. Traditionally, the English-language vernacular name "apes" does not include humans, but phylogenetically, humans (Homo) form part of the family Hominidae within Hominoidaea. Any answer other than the proposition that chimpanzees have only recently acquired predatory inclinations, for which there is no supportive evidence at all (Teleki, 1973a), would be welcome." Tilson3), and the siamang (Chivers 1972). Imitation is much more easily demonstrated in "great apes" than in other primate species. Here are four possible futures for the human race, based on some theories of continuing evolution. The diet of many of our ancestors certainly included marine resources – where people lived on the shores of lakes or the sea. Sir Wilfrid Le Gros Clark was one of those primatologists who developed the idea that there were trends in primate evolution and that the extant members of the order could be arranged in an ".. ascending series", leading from "monkeys" to "apes" to humans. Anthropoid apes are natural vegetarians (pp. The current section serves primarily to supplement the above articles, and to address other, newer rationalizations and misinformation promoted by dietary advocates who stubbornly cling to the "apes are vegetarians" myth. In fact, in a comparison of our DNA, scientists kept finding identical genes again and again. FFH: Orangutans consume 2% insects; from p. 11: "the 2% digression may be seen as incidental and insignificant." GO TO PART 3 - The Fossil-Record Evidence about Human Diet (Ape Diets: Myths, Realities, and Rationalizations, cont.) Easy Apple and Carrot Salad . Teleki [1981, pp. 11-12). Of further interest here is the information that termites are known to contain significant quantities of vitamin B-12; see Wakayama et al. Once evolutionary adaptation occurs, the "imitation" behavior would no longer be an imitation (supposing it were that, in some hazily conceived past)--it is natural.    Beyond Veg home   |   Feedback   |   Links. Insect food is the predominant animal matter resource for primates. They are distinguished from other primates by a wider degree of freedom of motion at the shoulder joint as evolved by the influence of brachiation. FFH then implies (assumes) that the behavior of the chimps of Gombe is in imitation of human behavior. Humans are very similar to anthropoid apes, which is established via a comparative anatomy/physiology table (pp. [7] Biologists have traditionally used the term "ape" to mean a member of the superfamily Hominoidea other than humans,[1] but more recently to mean all members of Hominoidea. Insects and other animal foods are nutrient-dense foods: they supply far more calories and nutrients per gram of edible portion than the same weight of most of the plant foods commonly consumed (i.e., fruits other than oily fruits, and leaves). GO TO PART 8 - Further Issues in the Debate over Omnivorous vs. Vegetarian Diets ), The gestural communication of apes and monkeys: Josep Call, Michael Tomasello – 2007, Learn how and when to remove this template message, Monkey § Historical and modern terminology, "Classification by molecules: What's in it for field botanists? Fossils and molecular data are two independent sources of information that should in principle provide consistent inferences of when evolutionary lineages diverged. Plant materials make up from 87% to >99% of the annual diet of great apes, the closest living relatives of modern humans (Homo sapiens sapiens). Insectivory by mountain gorillas is discussed further later in this section. In this article, a primary objective is to communicate concepts clearly and accurately but without undue complexity. [13][14][15]The gibbons split from the rest about 18 mya, and the hominid splits happened 14 mya (Pongo),[16] 7 mya (Gorilla), and 3–5 mya (Homo & Pan). GO TO PART 3 - The Fossil-Record Evidence about Human Diet In fact, most species of primate are omnivorous (see Harding [1981]) and omnivory should be considered an evolutionarily conservative and generalized trait among primates. It has been proposed that anatomical differences in human and great ape guts arose in response to species-specific diets and energy demands. Note that both insects mentioned are social insects; the consumption of social insects is efficient, as their concentration in nests allows easy harvesting of significant quantities. In the second place, we must remember that nearly all the other and more important differences between man and the Quadrumana are manifestly adaptive in their nature, and relate chiefly to the erect position of man; such as the structure of his hand, foot, and pelvis, the curvature of his spine, and the position of his head. See terminology of primate names. These studies have shown that in their natural environments, the non-human hominoids show sharply varying social structure: gibbons are monogamous, territorial pair-bonders, orangutans are solitary, gorillas live in small troops with a single adult male leader, while chimpanzees live in larger troops with bonobos exhibiting promiscuous sexual … ...the anomalous nature of an interspecific relationship that includes play with baboons, consumption of baboons, and competition with baboons for at least one kind of prey... In 1985, an influential article highlighted in my video The Problem With the Paleo Diet Argument was published proposing that our chronic diseases stem from a disconnect between … Linnaeus may have based Homo troglodytes on reports of mythical creatures, then-unidentified simians, or Asian natives dressed in animal skins. Chimpanzees, on the other hand, spend a remarkable amount of time, mental effort and tool use on searching out insects and feeding on them in every place where they have been intensively studied. Additionally, some of the rationalizations by dietary advocates that have been advanced as part of attempts to preserve the myth of "vegetarian apes" are discussed in "Selected Myths of Raw Foods." Chimps have lived in proximity to both humans and baboons for approximately 2-2.5 million years. Note that the footnote numbers in the quote above refer only to Hamilton and Busse [1978]. With all of the apes – chimps, baboons, orangutans, and gorillas, they eat diets rich in raw fruit, raw leaves, and shoots, insects, and nuts. Note: The above quote is included to specifically inform readers that there is no evidence that predation by chimps is a "new" behavior, and that there is extensive, complex, baboon/chimp interaction. The Gombe Preserve is small, and surrounded by human-populated areas.

Back to Research-Based Appraisals of Alternative Diet Lore Kortlandt [1984] also discusses insect consumption by chimps (p. 133): They are the four genera in the family Hominidae, namely Homo, Pan, Gorilla, and Pongo; plus four genera in the family Hylobatidae (gibbons): Hylobates, Hoolock, Nomascus and Symphalangus. Apes also have a much '''larger grinding surface on their molars''' to process leafy and fibrous plant material.In humans the canines are roughly the same size in the two sexes. Teleki [1981, pp. The booklet Fit Food for Humanity [Natural Hygiene Press 1982] makes what could be considered the classical comparative argument: humans vs. anthropoid apes. The chimpanzee diet is primarily vegetarian and consists of more than 300 different items, mostly fruits, berries, leaves, blossoms, and seeds but also bird eggs and chicks, many insects, and occasionally carrion. Therefore, cladistically, apes, catarrhines and related contemporary extinct groups such as Parapithecidaea are monkeys as well, for any consistent definition of "monkey". Additionally, some of the rationalizations by dietary advocates that have been advanced as part of attempts to preserve the myth of "vegetarian apes" are discussed in "Selected Myths of Raw Foods." One month a frugivore, later a folivore: how to classify? Rationalizations about Dietary Deviations among Primates However, the line of argument given above is incorrect and logically insufficient to establish the claimed result. Although the term "Orang Outang" is listed as a variety – Homo sylvestris – under this species, it is nevertheless not clear to which animal this name refers, as Linnaeus had no specimen to refer to, hence no precise description. GO TO NEXT PART OF ARTICLE Apes (including humans) possess the same general features that all primates share but they differ from other primates in a number of distinctive ways. SEE TABLE OF CONTENTS FOR: These are anatomical adaptations, first, to vertical hanging and swinging locomotion (brachiation) and, later, to developing balance in a bipedal pose. I expect that the known geographical distribution of predatory behavior will continue to expand as new chimpanzee projects are launched, though it is probable that some populations practice this behavior little or not at all, while others do so regularly and systematically (Teleki, 1975). As mentioned above, extreme diets are rare in nature. Instead, there is a spectrum of diets, and drawing lines or boundaries in the multi-dimensional dietary spectrum to distinguish between, say, frugivores and faunivores [faunivore = meat-eater] is a non-trivial problem. The interaction between baboons and chimps is quite interesting and serves to illuminate the shallow nature of the "imitation" argument. (Technical terms are used extensively in certain sections of this paper, but will be defined as we go along.) Additional evidence on the variability of orangutan diets is given in Knott [1998, p. 40]. Apes (Hominoidea /hɒmɪˈnɔɪdiːə/) are a branch of Old World tailless simians native to Africa and Southeast Asia. Regarding consumption of animal foods by primates, Hamilton and Busse [1978, p. 761] note: Ape features. [1984] for details. Kortlandt [1984] also discusses insect consumption by chimps (p. 133): 88 Ape Diet recipes. [31] Linnaeus named the orangutan Simia satyrus ("satyr monkey"). The primates called "apes" today became known to Europeans after the 18th century. Some literature may now use the common name "ape" to mean all members of the superfamily Hominoidea, including humans. PART 1 PART 2 PART 3 PART 4 PART 5 PART 6 PART 7 PART 8 PART 9 Preference for animal matter seems confirmed. Any answer other than the proposition that chimpanzees have only recently acquired predatory inclinations, for which there is no supportive evidence at all (Teleki, 1973a), would be welcome." GO TO PART 6 - What Comparative Anatomy Does and Doesn't Tell Us about Human Diet (Ape Diets: Myths, Realities, and Rationalizations, cont.) Chapman and Chapman [1990] reviewed 46 long-term studies of wild primates, with attention on monthly variations in diet. https://fanaticcook.blogspot.com/2009/06/are-ape-diets-suited-to-humans.html Regarding chimpanzee predation, Teleki [1981, p. 305] reports that: The structural problems in the above type of argument are addressed in later sections. How is it possible, then, that the primates serving as prey to chimpanzees in Gombe National Park, and possibly also at other sites, have not developed more successful defensive tactics? FFH then implies (assumes) that the behavior of the chimps of Gombe is in imitation of human behavior. GO TO PART 6 - What Comparative Anatomy Does and Doesn't Tell Us about Human Diet The claim that insect consumption by orangutans is "insignificant" is clearly an unproven assumption. REPLY/COMMENTS: The quote from FFH does not specify whether the 2% is by weight or feeding time. Ape diets, with emphasis on chimpanzees, are summarized in the article "Setting the Scientific Record Straight on Humanity's Evolutionary Prehistoric Diet and Ape Diets" on this site. There has been a gradual demotion of humans from being 'special' in the taxonomy to being one branch among many. Once evolutionary adaptation occurs, the "imitation" behavior would no longer be an imitation (supposing it were that, in some hazily conceived past)--it is natural.
