(2016) found that the specimens instead were a mix of 50% Basal Eurasian ancestral component (see genetics) and 50% Western Eurasian Unknown Hunter Gatherer (UHG) population related to European Western Hunter Gatherers.According to Bar-Yosef and Belfer-Cohen, "It seems that certain preadaptive traits, developed already by the Kebaran and Geometric Kebaran populations within the Mediterranean park forest, played an important role in the emergence of the new socioeconomic system known as the Natufian culture." Settlements occur in the woodland belt where oak and Pistacia species dominated.Some evidence suggests deliberate cultivation of cereals, specifically rye, by the Natufian culture, at Tell Abu Hureyra, the site of earliest evidence of agriculture in the world. Turner II, there is archaeological and physical anthropological evidence for a relationship between the modern Semitic-speaking populations of the Levant, Persian Gulf and the Natufians.
The period is commonly split into two subperiods: Early Natufian (12,500–10,800 BC) and Late Natufian (10,800–9,500 BC).
The Late Natufian most likely occurred in tandem with the Younger Dryas (10,800 to 9,500 BC).
The habitations of the Natufian are semi-subterranean, often with a dry-stone foundation. No traces of mudbrick have been found, which became common in the following Pre-Pottery Neolithic A (PPNA).
The round houses have a diameter between three and six meters, and they contain a central round or subrectangular fireplace.
Brace observed that the Natufian fossils lay between those of the Niger-Congo-speaking populations and the other samples, which he suggested may point to a Sub-Saharan influence in their constitution.
Subsequent ancient DNA analysis of Natufian skeletal remains by Lazaridis et al.
The underbrush of this open woodland was grass with high frequencies of grain.
The high mountains of Lebanon and the Anti-Lebanon, the steppe areas of the Negev desert in Israel and Sinai, and the Syro-Arabian desert in the east were much less favoured for Natufian settlement, presumably due to both their lower carrying capacity and the company of other groups of foragers who exploited this region.
Over the next two decades Garrod found Natufian material at several of her pioneering excavations in the Mount Carmel region, including el-Wad, Kebara and Tabun, as did the French archaeologist René Neuville, firmly establishing the Natufian in the regional prehistoric chronology.
