Archaeologist Patrick McGovern of the University of Pennsylvania claims that prehistoric communities cultivated wheat, rice, corn, barley, and millet primarily for the purpose of producing alcoholic beverages. Neanderthals, Denisovans, Hobbits, Stone Age Animals and Paleontology (25 articles) factsanddetails.com; Our ape ancestors gained a digestive enzyme capable of metabolizing ethanol near the time they began using the forest floor about 10 million years ago. One method is to look at the chemistry of a tooth’s dental enamel. No human remains were found in association with those fossilized prey bones, but A. afarensis remains were previously unearthed near the recent Afar Region discoveries. [Source: John Noble Wilford, New York Times, June 27, 2012 ], John Noble Wilford wrote in the New York Times: “The Au. Abstract. “All these species who were once in the human lineage, ventured out into this new world of foods 3.5 million years ago, but we don’t yet understand why that is.” |::|, “As well as looking at non-human primates, the researchers analysed fossils from other animals from the same era and did not find any evidence of a change in diet. *\*, “Macho and Shimizu think the emergence of photosynthesizing plants at the Miocene/Pliocene boundary led to "major global and local environmental changes." |~|, “P. Section 107, the material on this site is distributed without profit. while possibly avoiding contact with larger carnivores, such as hyenas and lions. The cranial capacity is larger, 420-500 cc (Conroy, 1998; … “We now have good evidence that some early hominins began using plant foods that are not used in abundance by living African apes today, and this probably led to a major change in the way they used the landscape. Gorillas have large stomachs which enable them to eat large amounts of foliage. “They were not competing for the same foods,” said Prof Thure Cerling from the University of Utah, who led one of the research papers. facial skeleton of the Australopithecus type species, A. africanus, is well suited to withstand premolar loads. They are made of foliage, branches, branches and loose soil. So, the markings found by anthropologists probably represent an individual’s “last meal,” whatever he or she was eating in the days before death. We conclude that Australopithecus africanus … However, we suggest that the mastication of either small objects or large volumes of food is unlikely to fully explain the evolution of facial form in this species. Australopithecus africanus was the first fossil hominin discovered in Africa. The forest provided shelter, shade, nuts, fruit and protection from predators. Early hominids may have scavenged meat from animals that died of natural causes or were killed by lions or leopards. In 1925 Dart proposed that his newly named genus Australopithecus was the ancestor of the genus Homo (Dart, 1925). |::|, “Researchers looked at samples from 175 hominins of 11 species, ranging from 1.4 to 4.1 million years old. It is thought that sediment in the bottom of a pool of water may have helped to protect the organic material from bacteria that would have caused them to rot and break down. Gorillas haven’t been observed using tools like chimpanzees. Different types of food interact differently with the teeth, leaving distinct textures and abrasions on the surface. Australopithecus groups in eastern Africa lived in the open savannah and fed on tough foods, like grasses. [Source: University or Arkansas, October 22, 2009]. They looked at complexity and directionality of wear textures in the teeth they examined. However, other researchers disagrees, claiming that the change in diet was instead due to the species exploiting a larger range of resources in a broader mosaic of habitats including grasslands, woodlands, and wetlands. afarens’ diet is a prime example of how multiple methods of analysis are necessary to gain an understanding of the past. *\*, “University of California at Berkeley paleontologist Tim White co-directed the recent project that brought to light the "Ardi" skeleton and Ardipithecus ramidus, which lived 4.4 million years ago. Australopithecus africanus ist eine Art der ausgestorbenen Gattung Australopithecus. The importance of diet in primate ecology has motivated the use of a variety of methods to reconstruct dietary habits of extinct hominin taxa. ..I have seen them break off a twig and carry it for a far as half a mile, going from one termite hill to another. “This opens a whole new set of questions.”, Cut Marks on 3.4-Million-Year-Old Bone: Earliest Evidence of Tools — And Meat Eating. "The enamel microstructure of A. anamensis indicates that their teeth were not well equipped to cope with acid erosion, but were well adapted to masticate an abrasive and hard diet." The carbon isotope analysis was done by his colleague and co-author Matt Sponheimer, a paleoanthropologist at the University of Colorado. afarensis is understanding the specie’s diet and therefore environment, as the environment determines what food is available. “We’ve seen over and over again,” she said: “These are very long relationships.”“ *^*, ‘Nutcracker Man’ Feasted On Tiger Nuts 2 Million Years Ago, In 2014, the University of Oxford reported: “An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago survived mainly on a diet of tiger nuts. Von der Art Australopithecus africanus, die vor drei bis zwei Millionen Jahren in Südafrika lebte, hatte man lange Zeit angenommen, dass sie für gewöhnlich keine Werkzeuge herstellte. (The Dikika baby is not truly Lucy's baby, since she lived 100,000 years before Lucy.) Experts at Santa Fe College in the US studied the gene ADH4 which produces an enzyme to break down alcohol in the body. But “shapes of the teeth alone tell you what the animal is capable of eating, not what they eat on a day-to-day basis,” he said.” Microwear and carbon analysis provides more detailed information on the ecology of hominins — how they lived based on what was immediately available to them.” /::\. *^*. Based on their strong and robust skulls, large mandibles, and thick enamel, some concluded that Au. [Source: Richard Gray, MailOnline, May 8, 2015 ^=^], Richard Gray wrote in MailOnline: The remains of plants and insects have also been found preserved in the cement-like breccia alongside the skeletons. “Results from stable isotopic analysis of the fossil teeth helped refine our picture of the paleoenvironment of the site, telling us that the majority of mammals at the site subsisted on grassy, well-watered resources,” Levin said. Eating tough grasses and tubers, for example, will leave behind scratches; hard nuts and seeds create pits. ^=^, Hominins Ate Crocodiles, Fish, Antelope, Turtles and Hippos 2 Million Years Ago, Johns Hopkins University reported: “A team of researchers that included Johns Hopkins University geologist Naomi Levin has found that early hominins living in what is now northern Kenya ate a wider variety of foods than previously thought, including fish and aquatic animals such as turtles and crocodiles. These caused more seasonality, which meant fluctuating food supplies, greater predation risk at the forest edge and increased competition for resources. “The new data suggests our simple story, of harder and harder diets over time, is not accurate,” said Peter Ungar, a paleoanthropologist at the University of Arkansas, whose lab does microscopic analysis of dental wear. One consequence could be that the dietary expansion led to a habitat expansion, as they could travel to more open habitats more efficiently. Nuts are chock filled with calories and with a rock a champ can eat 3,500 calories in just two hours. Australopithecus africanus (česky též Australopiték africký) je druh vyhynulého hominida, žijící na přelomu pliocénu a pleistocénu, před 3 - 2 miliony let v jižní Africe, na území dnešní Jihoafrické republiky.Ačkoliv není geologicky nejstarším australopitékem, byl rozeznán jako první a je tudíž typovým druhem celého rodu. For one thing, this was an animal that had to live out in open areas, just like early humans. In accordance with Title 17 U.S.C. It had an even larger jaw and teeth, with the biggest molars of any hominin. If they did engage in such activities Australopithecines had to compete with other predators and scavengers such as hyenas. Comptes Rendus Palevol journals.elsevier.com/ ; More studies are needed to determine which theory is most accurate. On the basis of recent isotope results, these hominins appear to have survived on a diet of C4 foods, which suggests grasses and sedges. Compared to Au. No African great apes, including chimpanzees, eat this type of food despite the fact it grows in abundance in tropical and subtropical regions. Instead of being adaptations to cracking open hard objects, the species’ massive teeth and jaws may have been traits that helped P. boisei handle very abrasive foods, including any grit clinging to blades of grass. A special gorilla treat is blackberries which they go through the trouble of picking off their thorny stems. 'Plant remains are captured in it - seeds, things like that - even food particulates that are captured in the teeth, so we can see what they were eating. Researchers thought that with the development of thick enamel, robust skulls and large chewing muscles, these species had evolved to eat hard, brittle foods. Hard and abrasive foods like nuts and seeds create complex patterns, tough foods such as leaves leave long, narrow scratches, and fruits leave pits. They also tended to live in the open savannahs of Africa. Other animals that lived around the same times as the Australopithecus species included baboons, cow-size pigs with meter-long tusks, massive buffalo, rodents, zebra, wildebeest rhinoceros, giraffes, and leaf-eating monkeys. “The study "reminds us that in paleontology, things are not always as they seem," commented Peter S. Ungar, chairman of anthropology at the University of Arkansas. Despite a recent rash of claims to the contrary based on misidentified fossils or erroneous dates (R. Leakey, 1970, 1973a, 1976a; Oxnard, 1975, 1979; M. Leakey, 1979), it has become increasingly evident that Dart was correct—Australopithecus was … The researchers discovered that microwear profiles of the three east African species, A. afarensis, A. anamensis and P. boisei, differed substantially from the two south African species, P. robustus and A. africanus, both of which showed evidence of diets consisting of hard and brittle food. Yet these are not high quality foods. afarensis. A grass diet is further hinted at by the carbon isotopes in P. boisei teeth: As much as 77 percent of their diet consisted of C4 plants (grasses and sedges). In 2010, Discovery News reported: “The discovery of a new “missing link” species of bull dating to a million years ago in Eritrea pushes back the beef steak dinner to the very dawn of humans and cattle. PBS: Human Evolution Library www.pbs.org/wgbh/evolution/library; “At sites of this age, we often consider ourselves lucky if we find any bone associated with stone tools. In South Africa, the data shows that Australopithecus groups may have had to fall back on hard, brittle foods like nuts, roots and seeds. Scientists said this apparently confirmed the carbon isotopic evidence for woodland diets. “This means that the humans have been eating Bos since the beginnings of the genus Homo,” said Martinez, referring to the genus to which humans belong. Cerling said it took some convincing to get the tooth samples for drilling from the National Museum of Kenya. sediba had a diet that was different from those of most early African hominins studied so far.” They also concluded that the “inferred consumption” of woodland products “increased the known variety of early hominin foods.” But there is still much that is unknown or unclear about the newfound species: how or if it is related to modern humans and just where it fits on the hominin family tree. afarensis, the questions still remain as to why they ate softer foods when their morphology suggests that they were able to consume tough foods, and why they expanded their diets to include more grasses and sedges. The Stone Age Institute stoneageinstitute.org; “Before now, we have never had such a wealth of data that actually demonstrates the wide variety of animal resources that early humans accessed.” Levin served as the main geologist on the team, which included scientists from the United States, South Africa, Kenya, Australia and the United Kingdom. A. africanus used to be regarded as ancestral to the genus Homo (in particular Homo erectus). The hominin’s massive molars and enormous jaw make it seem pretty obvious that the species spent a lot of time chomping on hard nuts and seeds. “The Lucy species and the species that came before it did not show the predicted trajectory.”. /::\, “There were similar differences in diet between groups of Paranthropus, a genus that lived about 2.7 million years ago, Dr. Ungar said. “The ancient pictures also include depictions of some of the other animals known to have left Africa by the same route: lions, cheetahs and hyena, she said. A comparison of the closely related P. bosei and Paranthropus robustus emphasized the puzzle of the Nutcracker Man. On the other hand, monkeys that eat a lot of fruit have low, rounded molar cusps. |~|, Paranthropus boisei “Grine and colleagues note that other lines of evidence directly record what an individual ate. The distinctive horns of the new Bos also broach some other interesting matters, said Olsen. Gracile australopiths had larger incisors, which indicates tearing food was important, perhaps eating scavenged meat. Then there is also a tantalizing resemblance between the newfound Bos and depictions of bulls in ancient petroglyphs found in western Saudi Arabia — along the route once taken by humans out of Africa.

"It stands to reason that other conclusions about other species also will require revisions," he said.Ungar, who was not part of the research team, suggested in 2007 the possibility that Nutcracker Man human ate grasses, based on tooth wear. Her findings help to explain a puzzle that has vexed archaeologists for 50 years. afarensis preferred softer foods such as leaves, grass, and fruit to that of hard and abrasive foods. However, the microwear texture analysis indicates that tough objects, such as grass and leaves, dominated Lucy’s diet. Before this discovery, the world’s oldest human evidence for butchery dated to 2.5 million years ago and came from Bouri and Gona, Ethiopia. *^*, “The million-year-old skull of the new Bos species, dubbed Bos buiaensis, has features of both earlier and later forms of Bos, which make it essentially a missing link between more modern cow-like species found in Eurasia and the earlier African cattle ancestors found alongside hominins and dating back 2.5 million years. The results suggest that Au. “Professor Lee-Thorp, a specialist in isotopic analyses of fossil tooth enamel, from the Research Laboratory for Archaeology and the History of Art, said: “We found evidence suggesting that early hominins, in central Africa at least, ate a diet mainly composed of tropical grasses and sedges. [Source: Sarah Knapton, The Telegraph, December 1, 2014 *|||*], “Scientists now believe that when primates left the trees and began walking on two feet they also started scooping up mushy, fermented fruit which was lying on the ground. |~|, “Grine and his colleagues suggest there may be a way to reconcile the paradox of P. boisei. The findings are published in the early online edition of Proceedings of the National Academy of Sciences. But here, we found everything from small bird bones to hippopotamus leg bones,” Braun said. The fossilized bones were found sandwiched between volcanic deposits, which permitted reliable dating of them. Their daughter-in-law, Maeve Leakey, is a co-author of the paper. These are ideas that anthropologists should further investigate. They also compared the microwear profiles of the ancient hominins to those of modern-day primates that eat different types of diets. It could also be argued that this dietary expansion was a key element in hominin diversification.” |::|, “The study has also answered, at least in part, what researchers have long been speculating – how so many large species of primate managed to co-exist. Gorillas essentially became herbivores, chimps evolved into fruit specialists and hominins became omnivores, which was a wise path to follow. PaleoAnthropology paleoanthro.org. Crocodiles and hippos were a danger. Macho explained, "This subtle interplay between diet, social structure and life history ultimately led to the evolution of our large brains. afarensis ate more tropical grasses, sedges, and succulents, a consumption pattern that differs from that of earlier species who tended to avoid these foods. “In 2004, the team discovered a 1.95 million-year-old site in northern Kenya and spent four years excavating it, yielding thousands of fossilized tools and bones. afarensis ate hard and brittle foods. Howard Hughes Medical Institute. Because different plants have unique ratios of carbon isotopes based on how they undergo photosynthesis, the carbon isotopes act as a stamp that records what the individual once ate. Australopithecus (OS-trə-lo-PITH-i-kəs; from Latin australis, meaning 'southern', and Greek πίθηκος (pithekos), meaning 'ape'), informal australopithecine or australopith (although the term australopithecine has a broader meaning as a member of the subtribe Australopithecina, which includes this genus as well as the Paranthropus, Kenyanthropus, Ardipithecus, and … Current consensus holds that the 3-million-year-old hominid Australopithecus africanus subsisted on fruits and leaves, much as the modern chimpanzee does. The authors argue that it is unlikely that the hominins would have eaten the leaves of the tropical grasses as they would have been too abrasive and tough to break down and digest. It is likely that they … Some times older gorilla couples share a nest. |::|, Diet of Australopithecus bahrelghazali, Who Lived in Chad Around Same Times as Lucy, The University of Oxford reported: “Researchers involved in a new study led by Oxford University have found that between three million and 3.5 million years ago, the diet of our very early ancestors in central Africa is likely to have consisted mainly of tropical grasses and sedges. Australopithecus afarensis and Australopithecus africanus are among the most famous of the extinct hominids. Chemical analysis of the teeth also suggests that some meat was included in the diet but not in significant amounts. afraensis. Researchers analysed fossilised tooth enamel of 11 species of hominins and other primates found in East Africa. The team theorizes that the wet and marshy environment gave early pre-humans a way to increase the protein in their diets (and grow larger brains!) In 2009, 3.4-million-year-old bones — found in Dikika, Ethiopia, near site where a Lucy-like hominin was discovered — with slashes, parallel marks and other cut marks that appear to have been made with stone tools, was presented as evidence that stone tools were produced more than 800,000 years than earlier thought and they could have been made by a possible human ancestor such as Lucy (Australopithecus afarenis). Then picks a straw or dried stem of grass and pokes this carefully down the hole. afarensis, researchers turned to morphological features relating to diet, such as skull and mandible (jaw) structure and teeth. (Grazil bedeutet "schlank", und in der Paläoanthropologie wird dieses Wort als Antonym zu "robust" gebraucht.) May 3, 2011]. "I saw them eaten on four occasion, and twice I found bits of bone in chimpanzee droppings. Elephants were a third larger than modern species. It’s not clear to us how early humans acquired or processed the butchered meat, but it’s likely that it was eaten raw,” Levin said. |~|, Alcohol Consumption May Be 10 Million Years Old, Study Says, A study published in 2014 suggests that primates may have begun drinking alcohol in the form of fermented fruit on the forest floor 10 million years ago. So ergab eine Computeranalyse der Fossilien Sts 5 und Sts 52 a (eines gut erhaltenen Oberkiefers), dass das Gebiss und der Bau der Gesichtsknochen geeignet waren, ähnlich wie bei den heute lebenden Javaneraffenhohem Druck standzuhalten. Animals such as zebra, wildebeest and elephants were probably too large for Australopithecus species to hunt with simple tools. It was hypothesised that the enzyme would not appear until the first alcohol was produced by early farmers. A crucial part of understanding Au. *|||*, “The findings could explain why tree-dwelling orang-utans still cannot metabolize alcohol while humans, chimps and gorillas can. SPECIMENS: many individuals. [Source: Charles Q. Choi, Live Science, May 20, 2015], Jennifer Viegas wrote in Discovery News: “Various types of electron microscopy, along with chemical analysis, determined that cut marks were inflicted while one or more individuals carved meat off the bones with a sharp stone tool. “This transition implies the genomes of modern human, chimpanzee and gorilla began adapting at least 10 million years ago to dietary ethanol present in fermenting fruit,” said Professor Matthew Carrigan, of Santa Fe College. “Exploring new environments and testing new foods, ultimately might be correlated with further changes in human history.” These four complementary studies give a persuasive account of shifts in dietary niche in East African hominins, Dr Louise Humphrey from the Natural History Museum in London, told BBC news. One type of carbon is produced from tree leaves, nuts and fruit, another from grasses and grasslike plants called sedges. The petroglyphs are at least 5,000 years old, she said, but very hard to date exactly. Close Encounters with Humankind: A Paleoanthropologist Investigates Our Evolving Species. One determination was immediately clear: Unlike chimpanzees, which are fruit specialists, the hominin couldn't have been much of a fruit-lover. One group of researchers conducted a microwear texture analysis on the teeth of various Au. Dr Macho suggests that hominins’ teeth suffered abrasion and wear and tear due to these starches. Instead, the patterns match those of gelada baboons, which eat a lot of tough grasses. Australopithecus afaraensis has both human and ape like characteristics with morphology traits to suggest that they could easily stand on two feet as well as be arboreal. Dr Macho’s study is based on the assumption that baboons intuitively select food according to their needs. The genus Australopithecus lived two million to four million years ago, At least eight species of Australopithecus (collectively known as Australopithecines) have been identified. Finding the isotopic traces of C3 or C4 plants in teeth indicate a hominin ate those plants (or animals that ate those plants). If you are the copyright owner and would like this content removed from factsanddetails.com, please contact me. One drawback of this method is that a tooth’s microwear is constantly reshaped whenever an individual eats. In some cases, these physical traits might reflect the fallback foods that a species relied on when its preferred foods were unavailable during certain times of the year. Die im Vergleich zum Menschen relativ großen Backenzähne werden als Anpassung an eine relativ harte Pflanzennahrung – darunter zumindest zeitweise hartschalige Samen – gedeutet. Die männlichen Mitglieder waren merklich größer als die weiblichen. One of the most common elements to look for is carbon. “An international research team extracted information from the fossilised teeth of three Australopithecus bahrelghazali individuals — the first early hominins excavated at two sites in Chad. “The preservation of the artifacts was so remarkable, in fact, that it allowed the team to meticulously and accurately reconstruct the environment, identifying numerous fossilized plant remains and extinct species that seem to be a sign that these early humans lived in a wet — and possibly even a marshy — environment. Sie waren uns in einigen Aspekten ähnlicher als bisher gedacht“, sagt … When the nuts are in season the sound of hammering chimps is so pronounced that Swiss Researchers Hedwige Boesch-Achermann said "Once I was leading someone here who was wondering what carpenters were doing in the forest." (The new Bos species) look so much like the pictures in Saudi Arabia,” said Olsen, “which people have thought were exaggerations.” *^*. Specimens of Australopithecus sediba from the site of Malapa, South Africa (dating from approximately 2 million years (Myr) ago) 1 present a mix of primitive and derived traits th One was an analysis of carbon isotopes extracted by laser from tooth enamel, one of the most durable and least contaminated body parts, and one that preserves chemical signatures of what was eaten in one’s youth. *\*, “The researchers therefore believe this early human ate nuts, root vegetables, insects -- such as termites -- and some meat. The surface wear on the teeth also point to eating hard foods and resemble the wear patterns seen in modern mangabey monkeys, which often eat nuts. Scientists believes that early Australopithecus species were equally at home in the forests and the savannah. ==, “Tiger nuts, which are rich in starches, are highly abrasive in an unheated state. The chimps prefer to hold the rock with two hands. Scientists are currently studying DNA linked with hormone oxytocin, which is associated with trust in the brain to gain insight into early man's social behavior. Die jüngsten Mitglieder der Gattung lebten bis in das Pleistozän vor 1,5 Millionen Jahren. “Hard, brittle foods like nuts and seeds tend to lead to more complex tooth profiles, while tough foods like leaves generally lead to more parallel scratches, which corresponds with directionality. “The most important point is that this Bos connects the African Bos with Eurasian bulls,” and so confirms the long, uninterrupted coexistence of humans and cattle from the earliest times, he told Discovery News. afarensis, Au. All this chewing put considerable strain on the jaws and teeth, which explains why “Nutcracker Man” had such a distinctive cranial anatomy. Although there is no evidence that early humans were actually herding early cattle 2.5 million years ago, the early humans and early cattle certainly shared the same landscape and beef was definitely on the menu all along, say researchers. robustus lived in South Africa 1.2 million to 1.8 million years ago when the region was an open grassland. “This challenges long-held assumptions and leads us to questions that must be addressed using other techniques,” Ungar said. Australopithecus anamensis, A. afarensis, A.africanus und A. garhi sind wegen ihres relativ leichten Körperbaus, speziell im Bereich des Schädels und der Zähne, als grazile Australopithecinen bekannt. This is why these hominins were able to survive for around one million years because they could successfully forage — even through periods of climatic change.’” ==, Paranthropus boisei (Australopithecus boisei or Nutcracker Man) No tools were found at that site, so it was unclear whether the marks were made with handmade tools or just naturally sharp rocks. Th… The teeth’s enamel chemistry further supports this conclusion: As much as 60 percent of the species’ diet consisted of C3 plants, which would include hard-shelled nuts and fruits (carbon chemistry can’t detect which part of a plant an animal ate). Her finding is grounded in existing data that details the diet of year-old baboons in Amboseli National Park in Kenya — a similar environment to that once inhabited by Paranthropus boisei. [Source: Jennifer Viegas Discovery News, August 11, 2010], Tia Ghose wrote in Live Science: “The bones were found several years ago in the history-rich sediments of Dikika, an area in the Awash River valley in Ethiopia,” an arid region that “has yielded some of the best examples of both early hominin fossils and fossils from anatomically modern early humans.
