Dark skin. All modern humans share a common ancestor who lived around 200,000 years ago in Africa. Comparisons between known skin pigmentation genes in chimpanzees and modern Africans show that dark skin evolved along with the loss of body hair about 1.2 million years ago and that this common ancestor had dark skin.
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
An ancestor is a parent or (recursively) the parent of an antecedent (i.e., a grandparent, great-grandparent, great-great-grandparent, and so forth). Ancestor is "any person from whom one is descended. In law the person from whom an estate has been inherited."
Australopithecus afarensis
According to genetic and fossil evidence, older versions of Homo sapiens evolved only in Africa, between 200,000 and 100,000 years ago, with members of one branch leaving Africa by 90,000 years ago and over time replacing earlier human populations such as Neanderthals and Homo erectus.
A hominid is any member of the biological family Hominidae. These are the "great apes", living and extinct. At present there are humans, chimpanzees, gorillas and orangutans. The word "hominid" has been used in various ways.
Other subdivisions reflect the evolution of life; the Archean and Proterozoic are both eons, the Palaeozoic, Mesozoic and Cenozoic are eras of the Phanerozoic eon. The three million year Quaternary period, the time of recognizable humans, is too small to be visible at this scale.
Omomyidae. Omomyidae is a family of early primates that radiated during the Eocene epoch between about 55 to 34 million years ago (mya).
Sahelanthropus tchadensis may have walked on two legs. However, because no postcranial remains (i.e., bones below the skull) have been discovered, it is not known definitively whether Sahelanthropus was indeed bipedal, although claims for an anteriorly placed foramen magnum suggests that this may have been the case.
Modern humans
Around 0.2% Denisovan ancestry are found in mainland Asians and Native Americans, whereas, in the Melanesian genome, it is 4–6% or 1.9–3.4%. New Guineans and Australian Aborigines have the most introgressed DNA, but Aborigines have less than New Guineans.The recent African origin paradigm 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.
Caves were the ideal place to shelter from the midday sun in the equatorial regions. The stable temperatures of caves provided a cool habitat in summers and a warm, dry shelter in the winter. Approximately 100,000 years ago, some Neanderthal humans dwelt in caves in Europe and western Asia.
The minimum widely accepted timeframe for the arrival of humans in Australia is placed at least 40,000 years ago. Many sites dating from this time period have been excavated. In Arnhem Land the Malakunanja II rock shelter has been dated to around 65,000 years old.
Gibraltar's Neanderthals may have been the last members of their species. They are thought to have died out around 42,000 years ago, at least 2,000 years after the extinction of the last Neanderthal populations elsewhere in Europe.
Dates and ranges
Oldowan stone tools are simply the oldest recognisable tools which have been preserved in the archaeological record. There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, between 2.4 and 1.7 mya.Neanderthals are named after the site from which they were first identified, the Neander Valley, at the time in the Rhine Province of the Kingdom of Prussia (now in North Rhine-Westphalia, Germany).
Evidence for the use of fire by Homo erectus by about 400,000 years ago has wide scholarly support.
The Hominidae (/h?ˈm?n?diː/), whose members are known as great apes or hominids (/ˈh?m?n?dz/), are a taxonomic family of primates that includes eight extant species in four genera: Pongo, the Bornean, Sumatran and Tapanuli orangutan; Gorilla, the eastern and western gorilla; Pan, the common chimpanzee and the bonobo;
What are the hominids in order?
