He later married and had children. Feral child Contact Contact Us Help. Prior to the s, feral and wild children stories were usually limited to myths and legends. Instead of going into a care facility, he went to live with vervet monkeys.

Further information: Homo and Names for the human species The binomial name Homo sapiens was coined by Linnaeus , The species was initially thought to have emerged from a predecessor within the genus Homo around , to , years ago. For this reason, a lineage-based cladistic definition of H. Such a cladistic definition would extend the age of H. Extant human populations have historically been divided into subspecies , but since around the s all extant groups have tended to be subsumed into a single species, H.
It has no formal authority associated with it. The horizontal axis represents geographic location; the vertical axis represents time in millions of years ago blue areas denote the presence of a certain species of Homo at a given time and place; late survival of robust australopithecines alongside Homo is indicated in purple.
Based on Springer , Homo heidelbergensis  is shown as diverging into Neanderthals, Denisovans and H. With the rapid expansion of H. Derivation from H. The horizontal axis represents geographic location; the vertical axis represents time in thousands of years ago. In addition, prehistoric Archaic Human and Eurasian admixture events in modern African populations are indicated. The divergence of the lineage leading to H. However, the oldest split among modern human populations such as the Khoisan split from other populations was more recently calculated by a study to date between , and , years ago,   and the earliest known H.
The time of divergence between archaic H. Since the s, the discovery of older remains with comparable characteristics, and the discovery of ongoing hybridization between "modern" and "archaic" populations after the time of the Omo remains, have opened up a renewed debate on the age of H. However, genetic evidence from the Sima de los Huesos fossils published in seems to suggest that H.
The term Middle Paleolithic is intended to cover the time between the first emergence of H. However, the brain case is quite rounded and distinct from that of the Neanderthals and is similar to the brain case of modern humans.
It is uncertain whether the robust traits of some of the early modern humans like Skhul V reflects mixed ancestry or retention of older traits. The observed rapid metabolic changes in brain and muscle, together with the unique human cognitive skills and low muscle performance, might reflect parallel mechanisms in human evolution.
Estimates of the age of Y-chromosomal Adam have been pushed back significantly with the discovery of an ancient Y-chromosomal lineage in , to likely beyond , years ago. Their separation time has been estimated in a study to be between —, years ago, compatible with the estimated age of early H. The study states that the deep split-time estimation of to thousand years ago is consistent with the archaeological estimate for the onset of the Middle Stone Age across sub-Saharan Africa and coincides with archaic H.
Eurasia was re-populated by early modern humans in the so-called "recent out-of-Africa migration" post-dating MIS5, beginning around 70,, years ago.
Some evidence suggests that an early wave humans may have reached the Americas by about 40—25, years ago. Evidence for the overwhelming contribution of this "recent" L3 -derived expansion to all non-African populations was established based on mitochondrial DNA , combined with evidence based on physical anthropology of archaic specimens , during the s and s, [note 9]  and has also been supported by Y DNA and autosomal DNA.
Certain genes related to UV-light adaptation introgressed from Neanderthals have been found to have been selected for in East Asians specifically from 45, years ago until around 5, years ago. Nevertheless, contemporary humans exhibit high variability in many physiological traits , and may exhibit remarkable "robustness". There are still a number of physiological details which can be taken as reliably differentiating the physiology of Neanderthals vs. Anatomical modernity See also: Behavioral modernity The term "anatomically modern humans" AMH is used with varying scope depending on context, to distinguish "anatomically modern" Homo sapiens from archaic humans such as Neanderthals and Middle and Lower Paleolithic hominins with transitional features intermediate between H.
Under this nomenclature Neanderthals considered H. The emergence of "gracile AMH" is taken to reflect a process towards a smaller and more fine-boned skeleton beginning around 50,—30, years ago.
