Ultraconserved words point to deep language ancestry across Eurasia

The search for ever deeper relationships among the World’s languages is bedeviled by the fact that most words evolve too rapidly to preserve evidence of their ancestry beyond 5,000 to 9,000 y. On the other hand, quantitative modeling indicates that some “ultraconserved” words exist that might be used to find evidence for deep linguistic relationships beyond that time barrier. Here we use a statistical model, which takes into account the frequency with which words are used in common everyday speech, to predict the existence of a set of such highly conserved words among seven language families of Eurasia postulated to form a linguistic superfamily that evolved from a common ancestor around 15,000 y ago. We derive a dated phylogenetic tree of this proposed superfamily with a time-depth of ∼14,450 y, implying that some frequently used words have been retained in related forms since the end of the last ice age. Words used more than once per 1,000 in everyday speech were 7- to 10-times more likely to show deep ancestry on this tree. Our results suggest a remarkable fidelity in the transmission of some words and give theoretical justification to the search for features of language that might be preserved across wide spans of time and geography.

The Archaeology News Network: Neolithic rock paintings discovered in Aydın

The Archaeology News Network: Neolithic rock paintings discovered in Aydın | Aux origines | Scoop.it
 

 

 

Similar rock paintings have previously been found in the Beşparmak Mountains, Bafa Lake and its environs, all of which are located in an area divided between Muğla’s Milas district and Aydın’s Koçarlı and Söke districts.


The paintings, which are believed to be 7,500 years old, were discovered as part of work conducted by Tekirdağ Namık Kemal University Archaeology Department Professor Neşe Atik initiated in 2000.

Atik said work was still continuing in the area. “The fact that these paintings, which are called the Latmos Region Prehistoric Rock Paintings and seen only in this region, have been found in Çine, opening a window on life in Çine in the Stone Age.”

Paleolithic human exploitation of plant foods during the last glacial maximum in North China

Three grinding stones from Shizitan Locality 14 (ca. 23,000–19,500 calendar years before present) in the middle Yellow River region were subjected to usewear and residue analyses to investigate human adaptation during the last glacial maximum (LGM) period, when resources were generally scarce and plant foods may have become increasingly important in the human diet. The results show that these tools were used to process various plants, including Triticeae and Paniceae grasses, Vigna beans, Dioscorea opposita yam, and Trichosanthes kirilowii snakegourd roots. Tubers were important food resources for Paleolithic hunter–gatherers, and Paniceae grasses were exploited about 12,000 y before their domestication. The long tradition of intensive exploitation of certain types of flora helped Paleolithic people understand the properties of these plants, including their medicinal uses, and eventually led to the plants' domestication. This study sheds light on the deep history of the broad spectrum subsistence strategy characteristic of late Pleistocene north China before the origins of agriculture in this region.

Un mini robot découvre des chambres sous la pyramides de Quetzalcoatl à Teotihuacan

Un mini robot découvre des chambres sous la pyramides de Quetzalcoatl à Teotihuacan | Aux origines | Scoop.it

Le temple fait partie du site archéologique connu sous le nom de Teotihuacan ("Cité des Dieux"), qui est bien connu pour ses nombreux bâtiments et pyramides.

Le robot, long de 90cm, nommé Tlaloc II-TC, a été descendu dans un tunnel inexploré vieux de 2000 ans. Il avait été découvert lorsque de fortes pluies avaient révélées un trou dans le temple en 2003.

Les archéologues de l'Institut national d'anthropologie et d'histoire (INAH), impliqués dans le projet "Tlalocan, Route sousterraine", espéraient trouver au moins une chambre à la fin du tunnel. Mais le robot télécommandé a renvoyé les images de trois anciennes pièces dans le tunnel.

DES FOSSILES NEANDERTALIENS DECOUVERTS EN GRECE

DES FOSSILES NEANDERTALIENS DECOUVERTS EN GRECE | Aux origines | Scoop.it

Des restes fragmentaires néandertaliens ont été découverts par une équipe franco-grecque en Grèce.

"Jusqu’à récemment, on en savait très peu sur la préhistoire ancienne de la Grèce, a avoué à Live Science la paléoanthropologue Katerina Harvati, principalement parce que les recherches archéologiques dans le pays se concentrent sur les périodes classiques et plus récentes. La Grèce se trouve pourtant directement sur l’une des routes les plus probables de dispersion depuis l’Afrique, via le Proche-Orient, des premiers humains et hominidés en Europe. De plus, le pays se situe au cœur d’une des trois péninsules méditerranéennes de l’Europe, ce qui en fait un refuge pour les espèces végétales et animales, et donc aussi humaines, durant la période glaciaire."

Modhur village throws up evidence to Dharmapuri’s neolithic connection - The New Indian Express

Modhur village throws up evidence to Dharmapuri’s neolithic connection - The New Indian Express | Aux origines | Scoop.it

A small village near Dharmapuri has been found to be archaeologically significant as historians have revealed that it has been inhabited since the Neolithic age, about 10,000 years ago.

Historians, who have been studying inscriptions and tools found in the area, are of the opinion that Modhur, situated about fifteen kilo metres from Dharmapuri town, was highly civilised and was most probably the capital for the Athiyaman kingdom. Stone hammers, grinding stones, rubbing stones, stone balls, and a terracotta statue of the mother goddess were excavated in the village.

Research pushes back origins of agriculture in China by 12,000 years

The discovery pushes back the roots of agriculture in China by 12,000 years. The global emergence of similar practices around 23,000 years ago hints that agriculture evolved independently around the world, perhaps as a response to climate change.
