The term Cro-Magnon (pronounced /kroʊˈmæɡnən/, French [kʀomaɲɔ̃]) refers to one of the main types of early modern humans of the European Upper Paleolithic. Current dating of Cro-Magnon bones point to more recent date 17,000 years. The earliest known remains of Cro-Magnon like humans are dated to 30,000 radiocarbon years. The name is taken from the cave of Crô-Magnon in southwest France, where the first specimen was found.

The Cro-Magnon term falls outside the usual naming conventions for early humans and is often used in a general sense to describe the oldest modern people in Europe, while remaining, anthropologically speaking, a specific (but very frequent) subtype among the fossil remains. In recent scientific literature the term "European early modern humans" is used instead.

The oldest definitely dated European early modern humans (EEMH) specimen ^[1] with modern and archaic, possibly Neanderthal, mosaic of traits is Oase 1 from 34,000–36,000 ¹⁴C years ago.^[2]

Assemblages and specimens

The geologist Louis Lartet discovered the first five skeletons of this type in March 1868 in the Cro-Magnon rock shelter. Other specimens have since come to light in other parts of Europe and neighboring areas.

Cro-Magnon 1 was discovered in rock shelter at Les Eyzies, Dordogne, France. The type specimen from this find is Cro-Magnon 1 dated 28,000 years BP^[3](27.680±270 BP). The skeletons showed the same high forehead, upright posture and slender (gracile) skeleton as modern humans.

The condition and placement of the remains of Cro-Magnon 1 along with pieces of shell and animal tooth in what appears to have been pendants or necklaces raises the question of whether they were buried intentionally. If Cro-Magnons buried their dead intentionally it suggests they had a knowledge of ritual, by burying their dead with necklaces and tools, or an idea of disease and that the bodies needed to be contained.^[4]

Analysis of the pathology of the skeletons shows that the humans of this period led a physically difficult life. In addition to infection, several of the individuals found at the shelter had fused vertebrae in their necks, indicating traumatic injury; the adult female found at the shelter had survived for some time with a skull fracture. As these injuries would be life threatening even today, this suggests that Cro-Magnons believed in community support and took care of each others' injuries.^[4]

Oase 1

The oldest EEMH remains are from Peştera cu Oase near the Iron Gates in the Danubian corridor. Oase 1 holotype revealed specific traits combining a variety of archaic Homo, derived early modern humans, and possibly Neanderthal features. Modern human attributes place it close to European early modern humans among Late Pleistocene samples. The fossil belongs to the few findings in Europe which could be directly dated and is considered the oldest known early modern human fossil from Europe. Two laboratories independently yielded collagen ¹⁴C averaging to 34,950, +990, and –890 B.P.^[5] The Oase 1 mandible was discovered February 16, 2002.

Cro-Magnon life

Cave painting from Lascaux, France dated to approximately 16,000 years ago (Upper Paleolithic).

Cro-Magnon were anatomically modern, only differing from their modern day descendants in Europe by their more robust physiology and slightly larger cranial capacity.^[13] Of modern nationalities, Finns are closest to Cro-Magnons in terms of anthropological measurements.^[14]

Surviving Cro-Magnon artifacts include huts, cave paintings, carvings and antler-tipped spears. The remains of tools suggest that they knew how to make woven clothing. They had huts, constructed of rocks, clay, bones, branches, and animal hide/fur. These early humans used manganese and iron oxides to paint pictures and may have created the first calendar around 15,000 years ago^[15].

The flint tools found in association with the remains at Cro-Magnon have associations with the Aurignacian culture that Lartet had identified a few years before he found the skeletons.

The Cro-Magnons are often blamed for causing Neanderthals extinction. Qafzeh humans seem to have coexisted with Neanderthals for up to 60,000 years in the Levant^[16] although Qafzeh are logical representative for subsaharan Africans but not for Cro-Magnon and subsequent Europeans^[17]. Earlier studies^[18] argue for more than 15,000 years of Neanderthal and EEMH coexistence in France^[19]; newer for east-west cline of patterns between Neanderthals and EEMH. Additionally the observed reversal of Châtelperronian over Aurignacian cultures may be mistaken conclusion based on interstratified paleo-layers, or layers of sediments disrupted by earlier quasi scientific digs in cave.^[20]

Genetics

A 2003 sequencing on two Cro-Magnons, 23 and 24,000 years old Pelosi 1 and 2, mitochondrial DNA, published by an Italo-Spanish research team led by David Caramelli, identified the mtDNA as Haplogroup N.^[21] Haplogroup N is found among modern populations of the Middle East, North Africa and Central Asia, and its descendant haplogroups are found among modern North African, Eurasian, Polynesian and Native American populations.^[22]
