Neanderthal in the context of "Human cannibalism"

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).These expansions are collectively known as Out of Africa I, in contrast to the expansion of anatomically modern humans (Homo sapiens) into Eurasia, which may have begun shortly after 0.2 million years ago (known in this context as "Out of Africa II").

The earliest presence of Homo (or indeed any hominin) outside of Africa dates to close to 2 million years ago.A 2018 study identified possible hominin presence at Shangchen, central China, as early as 2.12 Ma based onmagnetostratigraphic dating of the lowest layer containing what may possibly be stone artefacts.The oldest known human skeletal remains outside of Africa are from Dmanisi, Georgia (Dmanisi skull 4), and are dated to 1.8 Ma. These remains are classified as Homo erectus georgicus.

Cro-Magnons or European early modern humans (EEMH) were the first early modern humans (Homo sapiens) to settle in Europe and North Africa, migrating from Western Asia, continuously occupying the continent possibly from as early as 56,800 years ago. They interacted and interbred with the indigenous Neanderthals (H. neanderthalensis) of Europe and Western Asia, who went extinct 35,000 to 40,000 years ago. The first wave of modern humans in Europe (Initial Upper Paleolithic) left no genetic legacy to modern Europeans; however, from 37,000 years ago a second wave succeeded in forming a single founder population, from which all subsequent Cro-Magnons descended and which contributes ancestry to a majority of present-day Europeans, West Asians as well as some North Africans. Cro-Magnons produced Upper Palaeolithic cultures, the first major one being the Aurignacian, which was succeeded by the Gravettian by 30,000 years ago. The Gravettian split into the Epi-Gravettian in the east and Solutrean in the west, due to major climatic degradation during the Last Glacial Maximum (LGM), peaking 21,000 years ago. As Europe warmed, the Solutrean evolved into the Magdalenian by 20,000 years ago, and these peoples recolonised Europe. The Magdalenian and Epi-Gravettian gave way to Mesolithic cultures as big game animals were dying out, and the Last Glacial Period drew to a close.

Cro-Magnons were generally more robust than most living populations, having larger brains, broader faces, more prominent brow ridges, and bigger teeth. The earliest Cro-Magnon specimens also exhibit some features that are reminiscent of those found in Neanderthals. The first Cro-Magnons would have generally had darker skin tones than most modern Europeans and some West Asians and North Africans; natural selection for lighter skin would not have begun until 30,000 years ago. Before the LGM, Cro-Magnons had overall low population density, tall stature similar to post-industrial humans, and expansive trade routes stretching as long as 900 km (560 mi), and hunted big game animals. Cro-Magnons had much higher populations than the Neanderthals, possibly due to higher fertility rates; life expectancy for both species was typically under 40 years. Following the LGM, population density increased as communities travelled less frequently (though for longer distances), and the need to feed so many more people in tandem with the increasing scarcity of big game caused them to rely more heavily on small or aquatic game (broad spectrum revolution), and to more frequently participate in game drive systems and slaughter whole herds at a time. The Cro-Magnon arsenal included spears, spear-throwers, harpoons, and possibly throwing sticks and Palaeolithic dogs. Cro-Magnons likely commonly constructed temporary huts while moving around, and Gravettian peoples notably made large huts on the East European Plain out of mammoth bones.

The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. The term Middle Stone Age is used as an equivalent or a synonym for the Middle Paleolithic in African archeology. The Middle Paleolithic broadly spanned from 300,000 to 50,000 years ago. There are considerable dating differences between regions. The Middle Paleolithic was succeeded by the Upper Paleolithic subdivision which first began between 50,000 and 40,000 years ago. Pettit and White date the Early Middle Paleolithic in Great Britain to about 325,000 to 180,000 years ago (late Marine Isotope Stage 9 to late Marine Isotope Stage 7), and the Late Middle Paleolithic as about 60,000 to 35,000 years ago. The Middle Paleolithic was in the geological Chibanian (Middle Pleistocene) and Late Pleistocene ages.

According to the theory of the recent African origin of modern humans, anatomically modern humans began migrating out of Africa during the Middle Stone Age/Middle Paleolithic around 125,000 years ago and began to replace other Homo species such as the Neanderthals and Homo erectus.

Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents. They are believed to have begun approximately 2 million years ago with the early expansions out of Africa by Homo erectus. This initial migration was followed by other archaic humans including H. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of Denisovans and Neanderthals as well as modern humans. Early hominids had likely crossed land bridges that have now sunk.

Within Africa, Homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago. The recent African origin theory suggests that the anatomically modern humans outside of Africa descend from a population of Homo sapiens migrating from East Africa roughly 70–50,000 years ago and spreading along the southern coast of Asia and to Oceania by about 50,000 years ago. Modern humans spread across Europe about 40,000 years ago.

In archaeology, cave paintings are a type of parietal art (which category also includes petroglyphs, or engravings), found on the wall or ceilings of caves. The term usually implies prehistoric origin. Several groups of scientists suggest that the oldest of such paintings were created not by Homo sapiens, but by Denisovans and Neanderthals.

Discussion around prehistoric art is important in understanding the history of Homo sapiens and how human beings have come to have unique abstract thoughts. Some point to these prehistoric paintings as possible examples of creativity, spirituality, and sentimental thinking in prehistoric humans.

Jebel Irhoud or Adrar n Ighoud (Standard Moroccan Tamazight: ⴰⴷⵔⴰⵔ ⵏ ⵉⵖⵓⴷ, romanized: Adrar n Iɣud; Arabic: جبل إيغود, Moroccan Arabic: žbəl iġud), is an archaeological site located just north of the town of Tlet Ighoud in Youssoufia Province, approximately 50 km (30 mi) south-east of the city of Safi in Morocco.

It is noted for the hominin fossils that have been found there since the discovery of the site in 1961. Originally thought to be Neanderthals, the specimens have since been assigned to Homo sapiens and, as reported in 2017, have been dated to roughly 300,000 years ago. This makes the remains by far the earliest known examples of Homo sapiens, and suggests that rather than arising in East Africa approximately 200,000 years ago, modern humans have been present across the length of Africa 100,000 years earlier.

Homo erectus (/ˌhoʊmoʊ əˈrɛktəs/ lit. 'upright man') is an extinct species of archaic human from the Pleistocene, spanning nearly 2 million years. It is the first human species to evolve a humanlike body plan and gait, to leave Africa and colonize Asia and Europe, and to wield fire. Some populations of H. erectus were ancestors of later human species, including H. heidelbergensis — the last common ancestor of modern humans, Neanderthals, and Denisovans. As such a widely distributed species both geographically and temporally, H. erectus anatomy varies considerably. Subspecies are sometimes recognized: H. e. erectus, H. e. pekinensis, H. e. soloensis, H. e. ergaster, H. e. georgicus, and H. e. tautavelensis.

The species was first described by Eugène Dubois in 1893 as "Pithecanthropus erectus" using a skullcap, molar, and femur from Java, Indonesia. Further discoveries around East Asia were used to contend that humanity evolved out of Asia. Based on historical race concepts, it was argued that local H. erectus populations evolved directly into local modern human populations (polycentrism) rather than all humanity sharing a single anatomically modern ancestor (monogenism). As the fossil record improved over the mid-to-late 20th century, "Out of Africa" theory and monogenism became the consensus.

Homo antecessor (Latin for 'pioneer man') is an extinct species of archaic human recorded in the Spanish Sierra de Atapuerca, a productive archaeological site, from 1.2 to 0.8 million years ago during the Early Pleistocene. Populations of this species may have been present elsewhere in Western Europe, and were among the first to settle that region of the world, hence the name. The first fossils were found in the Gran Dolina cave in 1994, and the species was formally described in 1997 as the last common ancestor of modern humans and Neanderthals, supplanting the more conventional H. heidelbergensis in this position. H. antecessor has since been reinterpreted as an offshoot from the modern human line, although probably one branching off just before the modern human/Neanderthal split.

Despite being so ancient, the face is unexpectedly similar to that of modern humans rather than other archaic humans—namely in its overall flatness as well as the curving of the cheekbone as it merges into the upper jaw—although these elements are known only from a juvenile specimen. Brain volume could have been 1,000 cc (61 cu in) or more, but no intact braincase has been discovered. This is within the range of variation for modern humans. Stature estimates range from 162.3–186.8 cm (5 ft 4 in – 6 ft 2 in). H. antecessor may have been broad-chested and rather heavy, much like Neanderthals, although the limbs were proportionally long, a trait more frequent in tropical populations. The kneecaps are thin and have poorly developed tendon attachments. The feet indicate H. antecessor walked differently than modern humans.
