[4] [5] Early dispersals The Zinjanthropus boisei fossil found by Louis and Mary Leakey at Olduvai Gorge in 1959 was anatomically closest to which early South African hominin? [citation needed]. "Carnivoran Dispersal Out of Africa During the Early Pleistocene: Relevance for Hominins?". It is hard to say, however, whether settlement was continuous in Western Europe, or if successive waves repopulated the territory in glacial interludes. 55% of chimps at the Gombe reserve die of disease, most of them zoonotic. Australopithecus anamensis lived about 4.2 million years ago. As a result of this classification change, modern humans and all our extinct ancestors on our own branch of the evolutionary tree are now known as hominins rather than as hominids as they were formerly known in old classifications. The first Early Hominids for kids: Australopithecus. Lewis, M. E., & Werdelin, L. (2007). [57], This article is about spreading theory of early humans before about 200,000 years ago. • The fossil record indicates that there were a variety of species of early hominins adapted to various environments in sub- Saharan Africa. (1) Note: The word ‘tribe’ as used here and in biological classification has a particular meaning. Share. Kobe's 'Mr. Australopithecus - Australopithecus - Relationship to Homo: The first species to be identified as Australopithecus received that name in 1925, and, after nearly a century of discoveries, paleoanthropologists are able draw upon a fairly rich storehouse of fossil hominin specimens from Africa. ropithecus oswaldi lineage as early as 3.76 Ma mark a major ecological change within African primate communities. The earliest of the dated is Ain Hanech in northern Algeria (c. 1.8[14] – 1.2 Ma[15]), an Oldowan grade layer. The Pannonian plain, situated south-west of the Carpathian Mountains, was apparently characterized by a comparatively warm climate similar to that of the Mediterranean Area, while the climate of the western European paleobiogeographic area was mitigated by Gulf Stream influence and could support the episodic hominin dispersals toward the Iberian Peninsula. All hominids apart from Homo are known only from East and South Africa. What do we know about the adaptations of the hominins that … This is the carrying capacity. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. The first hominins were likely... omnivorous. [26] The first wave of "Out of Africa II and "earliest presence of H. sapiens in West Asia, may date to between .3 and 0.2 Ma,[26] and ascertained for 0.13 Ma. Group Of Answer Choices True False. They began to master the use of their hands and fingers. (Eds. The strait has maintained a width of at least 20 km for the whole of the Pleistocene. The earliest known evidence for African H. erectus, dubbed Homo ergaster, is a [54] Sheer body size, on the other hand, seems to have allowed for better walking energy efficiency and endurance. The use by hominins of the Levantine corridor, connecting Egypt via the Sinai peninsula with the Eastern Mediterranean, has been associated to the phenomenon of rising and declining humidity of the desert belt of northern Africa, known as the Sahara pump. The immediate ancestors of humans were Australopithecus. Foods derived from C4 plants were important in the dietary ecology of early Pleistocene hominins in southern and eastern Africa, but the origins and geographic variability of this relationship remain unknown. In: A. Baden et al. [citation needed]. More is known about another early species, Australopithecus afarensis, which lived between 3.9 and 2.9 million years ago. The earliest Homo erectus were contemporaries of the late Homo habilis in East Africa for several hundred thousand years. [51], In colder Eurasian times, the hominin diet would have to be principally meat-based and Acheulean hunters must have competed with cats. While most australopiths had a relatively slender, gracile build and teeth suited for soft food, there were also australopiths of a more robust build, dating to approximately 2.5 million years ago. (1) Early hominins were more widespread than thought (2) Bipedalism, thicker tooth enamel, and reduced canines are the first key derived features in hominins (3) Environment of earliest bipedal creatures was some kind of woodland Homo habilis could have developed some baseline behavioural flexibility prior to its expansion into the peripheries (such as encroaching into the predatory guild[42][43]). Homo Sapien Sapiens were also the first Early Hominids to create cave paintings. In any case, the morphology of H. floresiensis has been found to show greatest similarity with Australopithecus sediba, Homo habilis and Dmanisi Man, raising the possibility that the ancestors of H. floresiensis left Africa before the appearance of H. erectus. Discovery of Early Hominins The immediate ancestors of humans were members of the genus Australopithecus.The australopithecines (or australopiths) were intermediate between apes and people. Pilot Man' is now blamed for his death. [56] The ability for prolonged walking at a normal pace would have been a decisive factor for effective colonisation of Eurasia. These expansions are collectively known as Out of Africa I, in contrast to the expansion of Homo sapiens It became extinct in Africa c. 1.5 Ma,[49] but had already moved out through the Sinai, and is among the faunal remains of the Levantine hominin site of Ubeidiya, c. 1.4 Ma. At 1.8 Myr, there were … Lewis, M.E., Werdelin, L. (2010). Professor Dart soon realised that this find was very special and he named it Australopithecus africanus in 1925. In all likelihood, the ~34,000-year-old Sungir burials were created by people with spiritual beliefs and “modern” funerary behavior. Often we find them where carnivores have destroyed a lot of the bone. Early hominins[except Homo] show accelerated development all pattern like African apes. These hominids became extinct more than 1 million years ago and are not thought to be ancestral to modern humans, but rather members of an evolutionary branch on the hominin tree that left no descendants. [2], It has been suggested that Homo floresiensis was descended from such an early expansion. ’ s [2014] “ opportunistic use ” or James ’ s [1989] “ fortuitous use ”). I mean, it's warm in the library. Only in cases of a poor state of preservation of the left side, we mirrored the right side. Most attention as to the route taken from Africa to West Asia is given to the Levantine land corridor and the Bab-el-Mandeb straits. The oldest known Oldowan stone tools come from Gona, Ethiopia and date to _____ but are not in association with hominin remains. Unless otherwise noted, LibreTexts content is licensed by CC BY-NC-SA 3.0. grasses, some sedges and forbs, and a variety of. The skull shows that this Homo erectus was advanced in age and had lost all but one tooth years before death, and it is perhaps unlikely that this hominid would have survived alone. Thus, the earliest primates were diverging from early and still primitive placental mammals. Deep currents push westwards, and surface water flows strongly back into the Mediterranean. Carbon isotope data show that Australopithecus bahrelghazali individuals from Koro Toro in Chad are signifi-cantly enriched in 13C, indicating a dependence on C 4 resources. There is evidence of H. erectus in Yuanmou, China, dating to 1.7 Ma and in Sangiran, on Java, Indonesia, from 1.66 Ma. University. [40] [45] Moreover, some step-wise shrinking of the woodland and the associated reduction of hominin carrying capacity in the woods around 1.8 Ma, 1.2 Ma, and 0.6 Ma would have stressed the carrying capacity's pressure for adapting to the open grounds. Homo sapiens emerges in Africa before about 0.3 Ma from a lineage closely related to early H. Radiometric dates, however, have not been produced, and the artefacts might as well be from the Middle Pleistocene,[41] The latter connects the Horn of Africa and Arabia, and may have allowed dry passage during some periods of the Pleistocene. Bianchini, G. (1973). 3. The oldest Homo erectus fossils appear almost contemporaneously, shortly after two million years ago, both in Africa and in the Caucasus. These included upright walking, a reduction in canine dimorphism, and unusual demographic success. While a disease specific to hominins must keep its human host alive long enough to transmit itself, zoonotic diseases will not necessarily do so as they can complete their life cycle without humans. Although early hominins spread widely into Europe and Asia, their fossils are mostly found in areas that were tropical forests at the time. FKA twigs: LaBeouf had unusual relationship rules [52] The majority of these diseases are still restricted to hot and damp African environments. The fossil, which is informally called “Lucy,” is significant because it was the most complete australopith fossil found, with 40 percent of the skeleton recovered. These sites attest that early Homo erectus have crossed the North African tracts, which are usually hot and dry. This volume addresses many of the issues surrounding this initial hominin intercontinental dispersal. erectus as a temperature sensitive stenobiont, that failed to disperse north of the Alpide Belt. Since all the early hominin fossils have been found only in Africa, it seems that hominins were restricted to this continent for perhaps as long as 5 million years. Early Acheulean tools at Ubeidiya from 1.4 Ma[24] is some evidence for a continuous settlement in the West, as successive waves out of Africa after then would likely have brought Acheulean technology to Western Europe. Such an achievement by Homo erectus in the Early Pleistocene offers some strength to the suggested water routes out of Africa, as the Gibraltar, Sicilian, and Bab-el-Mandeb exit routes are harder to consider if watercraft are deemed beyond the capacities of Homo erectus. Hominins were using fi re that they created with fi re-making technology. Long before bipedal hominins first evolved in Africa, more primitive primates had diverged from even more distant mammalian ancestors. certainly, restricted to inter-glacials. Summary - Chapter 1-11 Summary - Chapter 6-10 Chapter 1. Paul Re: Early hominids and fire: JTEM is lucky in love AND money : 9/28/15 8:13 AM: Has anyone considered the possibility that even if early hominids didn't build houses or use fire, they could have just visited the local library? Males were up to 50 percent larger than females, a ratio that is similar to that seen in modern gorillas and orangutans. [21] Apparently, the faunal exchanges between southeastern Europe and the Near East and southern Asia were controlled by the complex interaction of such geographic obstacles as the Bosporus and the Manych Strait, the climate barrier from the north of the Greater Caucasus range, and the 41 kyr glacial Milankovitch cycles that repeatedly closed the Bosporus and thus triggered the two-way faunal exchange between southeastern Europe and the Near East, and, apparently, the further westward dispersal of the archaic hominins in Eurasia. 4.5–1.977 Million years ago. [4], Lithic analysis implies that Oldowan hominins were not predators. “Often we find them with seeds, fossil woods, abundant monkeys, and kudu [forest-dwelling antelopes] but lack of abundant aquatic mammals. With only a few Neanderthal fossils available to supplement their limited knowl-edge of living apes, they specu-lated about how … There were a number of Australopithecus species, often referred to as australopiths. A decrease in sea levels in the Pleistocene due to glaciation would not have brought this down to less than 10 km. So the earliest hominins were able to retain a core of technological and foraging skills. Homo is assumed to have emerged by around 2.8 million years ago, with Homo habilis being found at Lake Turkana, Kenya. [4]:3, For a given species in a given environment, available resources will limit the number of individuals that can survive indefinitely. Their molars show heavy wear, suggesting that they had a coarse and fibrous vegetarian diet as opposed to the partially carnivorous diet of the more gracile australopiths. Its brain was larger than that of A. afarensis at 500 cubic centimeters, which is slightly less than one-third the size of modern human brains. Early Pleistocene sites in North Africa, the geographical intermediate of East Africa and Georgia, are in poor stratigraphic context. In contrast, modern human males are approximately 15 to 20 percent larger than females. Until the early 1980s, early humans were thought to have been restricted to the African continent in the Early Pleistocene, or until about 0.8 Ma; Hominin migrations outside East Africa were apparently rare in the Early Pleistocene, leaving a fragmentary record of events. A key feature that Australopithecus had in common with modern humans was bipedalism, although it is likely that Australopithecus also spent time in trees. Question: All The Early Hominins From Africa Older Than 2.5 Million Years Possessed Large Brains That Were Not Much Smaller Than The Brain Of A Modern Homo Sapien. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. A. afarensis had smaller canines and molars compared to apes, but these were larger than those of modern humans. Please sign in or register to post comments. (anatomically modern humans) into Eurasia, which may have begun shortly after 0.2 million years ago (known in this context as "Out of Africa II").[1]. Chapter 10 The dispersal of the Genus Homo: Homo erectus and Contemporaries.... First dispersal of the Hominis: approx 2 million years ago, expanded out of Africa into other areas of The Old World. A new DNA analysis of 161 modern human genomes spanning islands across Southeast Asia and New Guinea suggests the Denisovans, an elusive early hominin species identified in … The brain size of Australopithecus relative to its body mass was also smaller than modern humans and more similar (although larger) to that seen in the great apes. In the mid-1970s, the fossil of an adult female A. afarensis was found in the Afar region of Ethiopia, dated to 3.24 million years ago. Some, like the australopiths , chose to eat large quantities of lower-quality plants; others, like early Homo , went for meat. [6] Genus Entrance into Eurasia across the strait of Gibraltar could explain the hominin remains at Barranco León in southeastern Spain (1.4 Ma)[19] and Sima del Elefante in northern Spain (1.2 Ma). For the first two thirds of our evolutionary history, we hominins were restricted to Africa. into other areas of the Old World. 4 plants were important in the dietary ecol-ogy of early Pleistocene hominins in southern and eastern Africa, but the origins and geographic variability of this relationship re-main unknown. Right? They might be the product of Australopithecus garhi or Paranthropus aethiopicus, the two known hominins contemporary with the tools. Legal. Dating from about two million years ago, hominin fossils first appear in Eurasia. The delineation of the "human" genus, Homo, from Australopithecus is somewhat contentious, for which reason the superordinate term "hominin" is often used to include both. Early Hominins Review - Summary Human Origins And Antiquity Helps to prepare for Exams . 29. Earliest hominids demonstrate major differences from fundamental behaviors typical of other primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. [48] However, Homo erectus appears to have followed animal migrations to the north during wetter periods, likely as a source of scavenged food. Another candidate is the Strait of Gibraltar. Dating from about two million years ago, hominin fossils first appear in Eurasia. There is little time between Homo erectus’ apparent arrival in South Caucasus around 1.8 Ma, and its probable arrival in East and Southeast Asia. [3] H. heidelbergensis from about 0.4 Ma develops its own characteristic industry, known as Clactonian. Oldowan grade tools are reported from Perim Island,[35] implying that the strait could have been crossed in the Early Pleistocene, but these finds have yet to be confirmed. Until the early 1980s, early humans were thought to have been restricted to the African continent in the Early Pleistocene, or until about 0.8 Ma; Hominin migrations outside East Africa were apparently rare in the Early Pleistocene, leaving a fragmentary record of events. This species demonstrates a trend in human evolution: the reduction of the dentition and jaw in size. Until the early 1980s, early humans were thought to have been restricted to the African continent in the Early Pleistocene, or until about 0.8 Ma; Hominin migrations outside East Africa were apparently rare in the Early Pleistocene, leaving a fragmentary record of events. The gracile australopiths had a relatively slender build and teeth that were suited for soft food and may have had a partially carnivorous diet, while the robust australopiths probably ate tough vegetation. … [46][47], With Homo erectus' new environmental flexibility, favourable climate fluxes likely opened it the way to the Levantine corridor, perhaps sporadically, in the Early Pleistocene. Braun (Eds.). into other areas of the Old World. The earliest well-dated Eurasian H. erectus site is Dmanisi in Georgia, securely dated to 1.8 Ma. [12] of Early Hominids Tim D. White, Berhane Asfaw, Yonas Beyene, Yohannes Haile-Selassie, C. Owen Lovejoy, Gen Suwa, Giday WoldeGabriel C harles Darwin and Thomas Huxley were forced to ponder human origins and evolution without a relevant fossil record. Fossil skeletons of hominins and our ancestors are still being recovered around the world, and there is no doubt that new techniques of imaging and molecular analysis will continue to provide evidence, supporting or refuting these categories, and always teaching us more about the early stages of human evolution. Practice Quiz for Analysis of Early Hominins: No. See the answer. [37][38] But the site of Pirro Nord in southern Italy, allegedly from 1.3 – 1.7 Ma,[20] suggests a possible arrival from the East. And over the millions of years most of the species existed, hominids changed; they evolved; some diverged and became new species. This suggests that the immediate ancestor of Homo erectus was an early Homo habilis or possibly another yet to be discovered species of early humans. Australopithecus (“southern ape”) is a genus of hominin that evolved in eastern Africa approximately 4 million years ago and became extinct about 2 million years ago. All people past and present, along with the australopithecines, are hominins. The earliest presence of Homo (or indeed any hominin) outside of Africa dates to close to 2 million years ago. Several expansions of populations of archaic humans (genus Homo) out of Africa and throughout Eurasia took place in the course of the Lower Paleolithic, and into the beginning Middle Paleolithic, between about 2.1 million and 0.2 million years ago (Ma). The presence of Lower Paleolithic human remains in Indonesian islands is good evidence for seafaring by Homo erectus late in the Early Pleistocene. Neither have been detected. Once hominins had moved out into drier and colder habitats of higher latitudes, one major limiting factor in population growth was out of the equation. stones from another area that were brought into the cave at the time that the early hominins were present : d) all of the above : 11. For tens of thousands of years, before we developed these abilities, modern humans and other hominins were fairly evenly matched, says Conard. They show that hominins at the time of Australopithecus were walking upright. (2011) suggest that it was still Homo habilis that reached West Asia, and that early H. erectus developed there. Until the early 1980s, early humans were thought to have been restricted to the African continent in the Early Pleistocene, or until about 0.8 Ma; Hominin migrations outside East Africa were apparently rare in the Early Pleistocene, leaving a fragmentary record of events. ), Interbreeding between archaic and modern humans, "The earliest modern humans outside Africa", "Bayesian analysis of a morphological supermatrix sheds light on controversial fossil hominin relationships", "Earliest human occupations at Dmanisi (Georgian Caucasus) dated to 1.85-1.78 Ma", "From Australopithecus to Homo: the transition that wasn't", "The earliest occupation of North Africa: a reply to Sahnouni, "Paleobiogeography of early human dispersal in western Eurasia: Preliminary results", "A Description of Two New Species of the Genus Rucervus (Cervidae, Mammalia) from the Early Pleistocene of Southeast Europe, with Comments on Hominin and South Asian Ruminants Dispersals", "Oldest Homo sapiens fossil claim rewrites our species' history", "Deeply divergent archaic mitochondrial genome provides lower time boundary for African gene flow into Neanderthals", "Genomic analyses inform on migration events during the peopling of Eurasia", "A Rare Deep-Rooting D0 African Y-chromosomal Haplogroup and its Implications for the Expansion of Modern Humans Out of Africa", "Absence of post-Miocene Red Sea land bridges: biogeographic implications", "An Early Pleistocene hominin mandible from Atapuerca-TD6, Spain", 10.1002/(SICI)1096-8644(199602)99:2<345::AID-AJPA9>3.0.CO;2-X, https://en.wikipedia.org/w/index.php?title=Early_expansions_of_hominins_out_of_Africa&oldid=1000135545, Articles containing Chinese-language text, Articles with unsourced statements from February 2016, Articles with unsourced statements from January 2020, Articles with unsourced statements from March 2016, All articles with vague or ambiguous time, Vague or ambiguous time from September 2018, Pages containing links to subscription-only content, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 January 2021, at 19:23. H. erectus would then have dispersed from West Asia, to East Asia (Peking Man) Southeast Asia (Java Man), back to Africa (Homo ergaster), and to Europe (Tautavel Man). Like all other primates, especially ground-living and edge species, these early hominins were very vulnerable to predators and this trait did not diminish greatly over time. Rather, our … Bednarik suggests that navigation had appeared by 1 Ma, possibly to exploit offshore fishing grounds. Still, these infections are well accustomed to human presence, having evolved alongside them. Those uplands would have been too dry and dusty for most of the time. Previously, it was thought that early homo sapiens had stayed close to the coast or savannahs, not infiltrating extreme environments until around 15,000 years ago. Adopted a LibreTexts for your class? This genus is of particular interest to us as it is thought that our genus, genus Homo, evolved from Australopithecus about 2 million years ago. [27] Genetic research also indicates that a later migration wave of H. sapiens (from .07-.05 Ma) from Africa is responsible for all to most of the ancestry of current non-African populations.[28][29][30]. The Paleoanthropologists who made that conclusion did so using homoplasies between Ramapithecus and hominins … Have questions or comments? Students also viewed. Early H. erectus would have lived face to face with H. habilis in East Africa for nearly half a million years. magnetostratigraphic dating of the lowest layer containing stone artefacts. Helpful? "Gli 'hacheraux' nei giacimenti paleolitici della Sicilia sud occidentale". of Questions= 13 INSTRUCTIONS: To answer a question, click the button in front of your choice. The ability to eat a range of C 3 and C 4 foods indicates that early Pliocene hominins were likely generalists who could thrive in different and perhaps varying environments. For the first two thirds of our evolutionary history, we hominins were restricted to Africa. Early expansions of hominins out of Africa From Wikipedia, the free encyclopedia. Upon reaching this threshold, individuals may find it easier to gather resources in the poorer yet less exploited peripheral environment than in the preferred habitat. [citation needed] As of 2012, the genetic analysis of human populations in Africa and Eurasia supports the concept that during the Paleolithic and Mesolithic periods, this route was more important for bi-directional human migrations between Africa and Eurasia than was the Horn of Africa. [16], Ferring et al. Hominids were the early proto-humans. But debates as to how closely related our ancient relatives were to us heated in paleontology and paleoanthropology: all scholars had to base those interpretations on was morphological variations. Human evolution, the process by which human beings developed on Earth from now-extinct primates. Australopithecina emerge about 5.6 million years ago, in East Africa (Afar Depression). There are reported sightings of “Bigfoot” What facts about apes and early hominins might lead you to question such reports? This species demonstrates a trend in human evolution: the reduction of the dentition and jaw … ... For this study the location of landmarks on one half of the face was sufficient and analyses were restricted to the left side. [36], The Strait of Gibraltar is the Atlantic entryway to the Mediterranean, where Spanish and Moroccan banks are only 14 km apart. Fauci reveals his reaction to Trump's bleach suggestion. all early hominins became committed terrestrial bipeds and expanded their diets to include a wider range of resources than their ancestors. It also had prognathic jaws, which is a relatively longer jaw than that of modern humans. The oldest known human skeletal remains outside of Africa are from Dmanisi, Georgia (Dmanisi skull 4), and are dated to 1.8 Ma. Which statement best describes women’s legal rights in the united states during the early 1800s? "Les 'Isthmes' hispano-marocain et Sicilo-Tunisien aux temps Acheuléens". A 2018 study claims evidence for human presence at Shangchen, central China, as early as 2.12 Ma based on magnetostratigraphic dating of the lowest layer containing stone artefacts. Comments. [10][11] A skull found at Dmanisi is evidence for caring for the old. During the succeeding Pliocene Epoch (5.3–2.6 mya) these changes only intensified. Thei rmaker could have been any of the East African hominins. There were a number of Australopithecus species, often referred to as australopiths. They made hooks, spears, knives, bow and arrows, and much more. women could study law to protect the few legal rights they had. Why did hominins first leave Africa in the early Pleistocene and not earlier? Gracile australopithecines (Australopithecus afarensis) emerge in the same region, around 4 million years ago. The strait has a major appeal in the study of Eurasian expansion in that it brings East Africa close to Eurasia. Australopithecus had a number of characteristics that were more similar to the great apes than to modern humans. A 2018 study claims human presence at Shangchen, central China, as early as 2.12 Ma based on Other related documents.

It is not certain, however, that this is sufficient proof for caring – a partially paralysed chimpanzee at the Gombe reserve survived for years without help. [53] Homo erectus had longer legs and shorter arms, revealing a transition to obligate terrestriality, though it remains unclear how this change in relative leg length might have been an advantage. Dating from about two million years ago, hominin fossils first appear in Eurasia. These hominids were larger and had large grinding teeth. Click here to let us know! heidelbergensis. The numerous hominin sites in the Levant, such as Ubeidiya and Misliya cave, are used as indicators of this migration route. Homo Sapien Sapiens were the mos talented toolmakers of all Early Hominids. Early hominins were at an evolutionary crossroads. They are all found only in Africa. Hominins were using fi re that they collected from a nat-ural source (Shimelmitz et al. Since all the early hominin fossils have been found only in Africa, it seems that hominins were restricted to this continent for perhaps as long as 5 million years. Its brain size was 380–450 cubic centimeters, approximately the size of a modern chimpanzee brain. known Middle Pleistocene site is, Chauhan, P. R. (2009). The sabre-tooth cat Megantereon was an apex predator of the Early and Middle Pleistocene (before MIS 12). Homo Sapien Sapiens were very talented Hominids. This opportunity was clearly present in Tanza-nia. For example, sexual dimorphism was more exaggerated than in modern humans. Review 1 … Table of Contents show 1. For the first two thirds of our evolutionary history, we hominins were restricted to Africa. When originally discovered, Ramapithecus was believed to be an early hominin. [4]:2 4. While Homo habilis was certainly bipedal, its long arms are indicative of an arboreal adaptation. “We're learning that these hominids are not ubiquitous; they were restricted to certain habitats,” says White. [17][18], It appears H. erectus took longer to move into Europe, the earliest site being Barranco León in southeastern Spain dated to 1.4 Ma, associated with Homo antecessor,[19] and a controversial Pirro Nord in Southern Italy, allegedly from 1.7 – 1.3 Ma.
