The Info List - Homo Antecessor

--- Advertisement ---

antecessor is an extinct human species (or subspecies) dating from 1.2 million to 800,000 years ago, that was discovered by Eudald Carbonell, Juan Luis Arsuaga
Juan Luis Arsuaga
and J. M. Bermúdez de Castro.[1] "The unique mix of modern and primitive traits led the researchers to deem the fossils a new species, H. antecessor, in 1997". Regarding its great age the species must be related to Out of Africa I, the first series of hominin expansions into Eurasia, making it one of the earliest-known human species in Europe.[2] The genus name Homo
is the Latin word for "human" whereas the species name antecessor is a Latin word meaning "explorer", "pioneer" or "early settler", assigned to emphasize the belief that these people belonged to the earliest known wave of migration to the European continent. Various archaeologists and anthropologists have debated how H. antecessor relates to other Homo
species in Europe, with suggestions that it was an evolutionary link between H. ergaster and H. heidelbergensis. Some anthropologists suggest H. antecessor may be the last common ancestor of modern humans and Neanderthals (via Homo heidelbergensis) because H. antecessor has a combination of primitive traits typical of earlier Homo
and unique features seen in neither Neanderthals nor Homo
sapiens. Author Richard Klein argues that it was a separate species evolved from H. ergaster.[3] Some scientists consider H. antecessor to be the same species as H. heidelbergensis, who inhabited Europe
from 600,000 to 250,000 years ago in the Pleistocene.[4] As a complete skull has yet to be unearthed, with only fourteen fragments and lower jaw bones known, these scholars point out that "most of the known H. antecessor specimens represent children"; as "most of the features tying H. antecessor to modern people were found in juveniles, whose bodies and physical features change as they grow up and go through puberty. It’s possible that H. antecessor adults didn't really look much like H. sapiens at all".[2][5] The best-preserved fossil is a maxilla that belonged to a ten-year-old individual found in Spain. Based on palaeomagnetic measurements, it is thought to be older than 857–780 ka.[6] In 1994 and 1995, 80 fossils of six individuals who may have belonged to the species were found in Atapuerca, Spain. At the site were numerous examples of cuts where the flesh had been flensed from the bones, which indicates that H. antecessor may have practiced cannibalism.[7] Footprints presumed to be from H. antecessor dating to more than 800,000 years ago have been found at Happisburgh on the coast of Norfolk, England.[8][9][10][11]

H. antecessor's discoverers—including José Bermúdez de Castro of Spain’s National Museum of Natural Sciences, Juan Luis Arsuaga
Juan Luis Arsuaga
of the Universidad Complutense in Madrid
and Eudald Carbonell
Eudald Carbonell
of the University of Tarragona—suggest H. antecessor may have evolved from a population of H. erectus living in Africa more than 1.5 million years ago and then migrated to Europe, further arguing that H. antecessor gave rise to H. heidelbergensis, which then gave rise to Neanderthals, without contradicting the previous phylogenetic analysis.[12][13] A 2013 DNA analysis from a 400,000-year-old femur from Spain's Sima de los Huesos in the Atapuerca Mountains—the oldest hominin sequence yet published—did not help to overcome contradictions. Results "left researchers baffled" as the sequence "suggests [a closer] link to [the] mystery population" of the Denisovans instead of the Neanderthals as was anticipated.[14] In 2016, nuclear DNA analysis results determined the Sima hominins to be Neanderthals and not Denisova hominins, and that the divergence between Neanderthals and Denisovans predates 430,000 years.[15][16] According to the Science X Network the excavation team at the cave site of Gran Dolina
Gran Dolina
has succeeded to provide conclusive dating of the strata where the Homo
antecessor fossils were found. A 2014 publication in the Journal of Archaeological Science states that the sediment of Gran Dolina
Gran Dolina
is 900,000 years old.[17] A review of the Spanish National Research Centre for Human
Evolution (CENIEH) in 2015, titled " Homo
antecessor: The state of the art eighteen years later" only yields vague statements on the species' phylogenetic position: "... a speciation event could have occurred in Africa/Western Eurasia, originating a new Homo
clade", and further: " Homo
antecessor ... could be a side branch of this clade placed at the westernmost region of the Eurasian continent".[18] Physiology[edit] H. antecessor was about 1.6–1.8 m (5½–6 feet) tall, and males weighed roughly 90 kg (200 pounds). Their brain sizes were roughly 1,000 to 1,150 cm³, smaller than the 1,350 cm³ average of modern humans. Due to fossil scarcity, very little more is known about the physiology of H. antecessor, yet it was likely to have been more robust than H. heidelbergensis.[19] According to Juan Luis Arsuaga, one of the co-directors of the excavation in Burgos, H. antecessor might have been right-handed, a trait that makes the species different from the other apes. This hypothesis is based on tomography techniques. Arsuaga also claims that the frequency range of audition is similar to H. sapiens, which makes him suspect that H. antecessor used a symbolic language and was able to reason.[19] Arsuaga's team is currently pursuing a DNA map of H. antecessor. Based on teeth eruption pattern, the researchers think that H. antecessor had the same development stages as H. sapiens, though probably at a faster pace. Other significant features demonstrated by the species are a protruding occipital bun, a low forehead, and a lack of a strong chin. Some of the remains are almost indistinguishable from the fossil attributable to the 1.5-million-year-old Turkana Boy, belonging to H. ergaster. Fossil sites[edit]

The only known fossils of H. antecessor were found at two sites in the Sierra de Atapuerca region of northern Spain
( Gran Dolina
Gran Dolina
and Sima del Elefante). The type specimen for H. antecessor is ATD 6-5, dating to approximately 780,000 years ago.[20] Other sites yielding fossil evidence of this hominid have been discovered in the United Kingdom and France. Gran Dolina[edit] Archaeologist Eudald Carbonell
Eudald Carbonell
i Roura of the Universidad Rovira i Virgili in Tarragona, Spain
and palaeoanthropologist Juan Luis Arsuaga Ferreras of the Complutense University of Madrid
Complutense University of Madrid
discovered Homo antecessor remains at the Gran Dolina
Gran Dolina
(literally “Big Sinkhole”) site in the Sierra de Atapuerca, east of Burgos
in what now is Spain. The H. antecessor remains have been found in level 6 (TD6) of the Gran Dolina site. More than 80 bone fragments from six individuals were uncovered in 1994 and 1995. The site also had included approximately 200 stone tools and 300 animal bones. Stone tools including a stone carved knife were found along with the ancient hominin remains. All these remains were dated at least 900,000 years old.[21] The best-preserved remains are a maxilla (upper jawbone) and a frontal bone of an individual who died at the age of 10–11. Sima del Elefante[edit] On June 29, 2007, Spanish researchers working at the Sima del Elefante (“Pit of the Elephant”) site in the Atapuerca Mountains
Atapuerca Mountains
of Spain announced that they had recovered a molar dated to 1.2 to 1.1 million years ago. The molar was described as "well worn" and from an individual between 20 and 25 years of age. Additional findings announced on 27 March 2008 included a mandible fragment, stone flakes, and evidence of animal bone processing.[22] These remains are the oldest hominid remains in Europe
after Homo
erectus georgicus from Dmanisi, Georgia (dated 1.8 million years ago) and an infant tooth from Orce, Spain
which has not received species assignation (1.4 million years).[23] Suffolk, England[edit]

In 2005, flint tools and teeth from the same strata as fossils of the water vole Mimomys savini, a key dating species, were found in the cliffs at Pakefield
near Lowestoft in Suffolk. This suggests that hominins existed in England 700,000 years ago, potentially a cross between Homo
antecessor and Homo
heidelbergensis.[24][25][26][27][28] Norfolk, England[edit] In 2010, stone tool finds were reported in Happisburgh, Norfolk, England,[29][30] thought to have been used by H. antecessor, suggesting that the early hominin species also lived in England about 950,000 years ago—the earliest known population of the genus Homo
in Northern Europe. In May 2013, sets of fossilized footprints were discovered in an estuary at Happisburgh.[10] They are thought to date from 800,000 years ago and are theorized to have been left by a small group of people, including several children and one adult male. The tracks are considered the oldest human footprints outside Africa and the first direct evidence of humans in this time period in the UK or northern Europe, previously known only by their stone tools.[31] Within two weeks, the tracks had been covered again by sand, but scientists made 3D photogrammetric images of the prints, and attributed them to H. antecessor.[9] Lézignan-la-Cèbe, France[edit] Twenty tools dating back to the Paleolithic (pebble culture, 1.6 million years ago) were found in 2008.[32] See also[edit]
