accountThe oldest stone tools, dating to 3.3 million years ago, were discovered at the site of Lomekwi in northwest Kenya and appear to be the work of small-brained australopiths rather than the genus Homo.
claimThe presence of starch-consuming Streptococcus bacteria in Neandertals and modern humans indicates that the genus Homo had adapted to consuming abundant starchy plant foods by the time Neandertals and modern humans diverged from their last common ancestor approximately 600,000 years ago.
accountEarly members of Homo at Kanjera South used stone tools to extract meat and marrow from mammals ranging from small antelopes to bovids the size of wildebeests.
measurementHomo species were exploiting aquatic foods, including fish and turtles, in the Turkana Basin of Kenya as early as 1.95 million years ago.
accountEarly members of Homo at Kanjera South transported rocks from as far as 10 kilometers away to manufacture stone tools.
claimAustralopithecus microwear patterns on teeth reflect a narrow range of food types, whereas early Homo shows a wider range, and later members of the genus Homo show patterns indicating an even greater variety of foods.
perspectiveRichard Wrangham of Harvard University has proposed that cooking food, which makes it easier to chew and digest, may have provided Homo species with the extra fuel required to power a larger brain.
claimEarly members of Homo at Kanjera South likely hunted small antelopes and scavenged larger animals.
claimThe genus Homo became a more versatile eater capable of consuming a wider variety of foods than its predecessors, which facilitated the expansion into new environments with diverse food sources.
claimThe genus Homo evolved smaller teeth with crests that were better suited for consuming tough foods, including meat.
claimThe adaptation to a high-carbohydrate diet may have contributed to brain expansion in the genus Homo.
The role of Plant Foods in the evolution and Dispersal of early Humans kernsverlag.com Jul 30, 2022 6 facts
claimThe increase in meat consumption associated with late Australopithecus and early Homo correlates with the evolution of larger relative brain size, increased body size, simplified digestive anatomy, and expanded geographical range observed in Homo erectus by 1.8 million years ago, as noted by Wood and Collard (1999).
claimChanges in Homo masticatory capacity, specifically decreased enamel thickness and increased shearing quotients compared to Australopithecus, support the inclusion of tough and elastic resources like meat in early Pleistocene diets, according to Ungar (2004).
claimBen-Dor and colleagues hypothesize that Middle Pleistocene Homo species specialized in hunting large prey, such as elephants, to obtain the high-fat diet necessary to sustain a hyper-carnivorous lifestyle (Ben-Dor et al. 2011, 2021; Ben-Dor and Barkai 2021).
claimBen-Dor and Barkai argue that a decrease in prey size, caused by over-exploitation and environmental changes, forced Middle Pleistocene Homo to reduce fat intake, broaden their diet, and develop more complex behavioral and cultural adaptations.
referenceF. Détroit and colleagues identified a new species of Homo from the Late Pleistocene of the Philippines in a 2019 study.
claimPhysiological traits unique to the Homo genus, such as relatively large brain size, decreased gut size, and changes in dental morphology and locomotive adaptations, suggest innovative dietary choices compared to other primates.

referenceMcHenry, H. M. and Coffing, K. (2000) published 'Australopithecus to Homo: transformations in body and mind' in the Annual Review of Anthropology, volume 29, issue 1, pages 125-146.
claimThe emergence of early Homo is associated with a reduction in mandibular size, robusticity, enamel thickness, and buttressing of mastication, suggesting a shift in food use patterns or food processing.
Psychedelics, Sociality, and Human Evolution frontiersin.org 2 facts
claimExposures to psychedelic fungi by australopithecines and early Homo during the Pleistocene epoch (beginning 2.5 million years ago) are implied by the presence of these fungi in African grasslands, particularly growing on the dung of ungulates, which were a target of hominin scavenging and hunting.
referenceKatharine Milton (2003) argued that animal source foods played a critical role in human (Homo) evolution.
The Evolution of Human Nutrition carta.anthropogeny.org Dec 7, 2012 2 facts
claimAbout 2.5 million years ago, as forests gave way to savanna, the genus Paranthropus evolved with specialized teeth and jaws, while the genus Homo evolved with a broader variety of foods.
claimPre-agriculture human diets were not uniform, and dietary shifts are associated with major evolutionary events in human prehistory, including the appearance of the genus Homo, the appearance of Homo erectus, and the migration of humans out of Africa.

claimThe term 'Hominini' is a formal biological classification level situated between the genus level (such as Homo or Australopithecus) and the family level (Hominidae).
referencePeters and O'Brian (1981) analyzed the plant-food niche of early hominids by comparing plant exploitation patterns among Homo, Pan, and Papio in eastern and southern Africa.

claimMagill claims that data shows the environment changed dramatically over a short time, coinciding with the establishment of the genus Homo and the first evidence of tool use.
claimMagill states that changes in food and water availability were linked to major evolutionary changes in the area where the genus Homo was established.

claimHomo erectus appeared in Africa approximately two million years ago, evolving from either a late form of australopith or a primitive form of Homo.

claimEarly Homo species exhibited reduced mandibular size and enamel thickness, which suggests shifts in food processing and varied dietary practices as these species expanded their food use patterns.
