Discovered by Philippe-Charles Schmerling

Engis 2 refers to part of an assemblage, discovered in 1829 by Dutch physician and naturalist Philippe-Charles Schmerling in the lower of the Schmerling Caves. The pieces that make up Engis 2 are a partially preserved calvaria (cranium) and associated fragments of an upper and a lower jaw, a maxillary bone and an upper incisor tooth of a two to three year old Neanderthal child. The Schmerling Caves are situated just north of the Belgian municipality Engis, whence the name of this group. [1] In 1833 Schmerling described [2] and publicized the find, which included animal bones and stone tools. Recognizing their old age, he associated them with the "Ethiopian Type" of the diluvial period. [3] Although it was not recognized as such until 1936, the publication represents the first scientific description of a Neanderthal fossil. [4]

Early Misclassification

Originally misclassified as "modern", the fossil received little attention after its publication in the 19th century as it was compared to Engis 1 - the almost perfectly preserved skull of an adult Homo sapiens . In 1758, Carl Linnaeus had published the 10th edition of his work Systema Naturae in which Homo sapiens as a species name was introduced to the public, yet without a thorough diagnosis and without a precise description of the species-specific characteristics. [5] As a result, any criteria by which a fossil of the species Homo sapiens could be classified into and distinguished from the genus Homo did not exist in the early 19th century. [6]

Even Thomas Henry Huxley, a supporter of Darwin's theory of evolution, saw in the 1863 findings of the Engis cave a "man of low degree of civilization" and also interpreted the Neandertal 1 fossils of the Kleine Feldhofer Grotte unearthed in 1856 as belonging within the range of variations of modern man. [7] Additionally, the skull of an infant Neanderthal and an equally old child of anatomically modern humans are of far greater resemblance than their respective adult skulls. The vast majority of the anthropologists of the 19th and early 20th century considered all hominid fossils as belonging to representatives of early "races" of modern man. Hence it was incorrectly believed that the modern man's skull Engis 1 must be related to the child's skull Engis 2. [8]

Reclassification and Age

Two radiocarbon dates are available for Engis 2. However, the earlier result of 26,820 ± 340 radiocarbon years before present (BP) was considered to be too young by the authors and likely to be a result of contamination, so has been discarded. The more accurate date is 30,460 ± 210 radiocarbon years BP, which corresponds to 34,590–36,110 years BP after calibration. [9] The assignment of Engis 2 to Homo neanderthalensis and Engis 1 to Homo sapiens was primarily based on anatomical and chronological comparisons as Engis 2 was recovered in the context of Neanderthal Mousterian artefacts. [10]

Condition of the bones and associated assemblages

In 1986, cut marks were found on the top of the skull of Engis 2, [11] which were later identified as to be preparation damage " formed during restoration of the vault, moulding striae formed when mold part lines were incised into the fossil and profiling striae formed when craniograms were made with sharp steel instrument tips." [12] The findings are preserved at the Collections de Paléontologie Animale et Humaine of the University of Liège. The bone fragments called Engis 3 have gone missing. [13] The evolutionary origin of an ulna (forearm bone) fragment called Engis 4 discovered in 1872 is unclear; it has to date not been associated with a specific taxon. [14] [15] [16]

He is the leading proponent of the multiregional evolution hypothesis that explains the evolution of Homo sapiens as a consequence of evolutionary processes and gene flow across continents within a single species. Wolpoff authored the widely used textbook Paleoanthropology, and co-authored Race and Human Evolution: A Fatal Attraction, which reviews the scientific evidence and conflicting theories about the interpretation of human evolution, and biological anthropology's relationship to views about race.

<i>Homo</i> Genus of hominins that includes humans and their closest extinct relatives

Homo is a monotypic genus that emerged from the genus Australopithecus and encompasses the extant species Homo sapiens and several extinct species classified as either ancestral to or closely related to modern humans, including Homo erectus and Homo neanderthalensis. The oldest member of the genus is Homo habilis, with records of just over 2 million years ago. Homo, together with the genus Paranthropus, is probably sister to Australopithecus africanus, which itself had split from the lineage of Pan, the chimpanzees.

Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence and cultural evidence.

Neanderthals became extinct around 40,000 years ago.

It is likely that multiple factors caused the demise of an already low population.

Archaic humans is a broad category denoting all species of the genus Homo that are not Homo sapiens.

In 1864, the fossil's description was first published in a scientific magazine and officially named. Neanderthal was not the first Neanderthal fossil discovery. Other Neanderthal fossils had been discovered earlier, but their true nature and significance had not been recognized, and, therefore, no separate species name was assigned.

It is noted for the hominin fossils that have been found there since the discovery of the site in 1960. 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.

The site is a significant locality of regional Neanderthal and European early modern human occupation, as thousands of fossils and artifacts were discovered that are all attributed to a long and contiguous stratigraphic sequence from 120,000 years ago, the Middle Paleolithic to less than 5,000 years ago, the late Neolithic. A robust sequence of sediments was identified during extensive excavations by geologist Edouard Dupont, who undertook the first probings as early as 1867. The site was added to the Belgian National Heritage register in 1976.

With an estimated height of 1.78 m, it is considerably taller than any other known Neanderthal, and its skull has by far the largest cranial capacity of any human skull in the fossil record. According to Ralph Holloway, this makes it one of the most famous Neanderthal specimens.

The Schmerling Caves are a group of caves located in Wallonia on the right bank of the stream called the Awirs, near the village of Awirs in Flémalle, Belgium. The caves are notable for their past fossil finds, particularly of hominins. They were explored in 1829 by Philippe-Charles Schmerling, who discovered, in the lower cave, the remains of two individuals, one of which, now known as Engis 2, was a fossil of the first Neanderthal ever found; the other was a Neolithic homo sapiens. Also known as Trô Cwaheur or Trou Caheur, this lower cave has since collapsed. A third cave was destroyed because of work on the adjacent quarry, the Ancienne Carrière des Awirs.

Apidima Cave is a complex of five caves four small caves located on the western shore of Mani Peninsula in Southern Greece. A systematic investigation of the cave has yielded Neanderthal and Homo sapiens fossils from the Palaeolithic era.
