There are a number of large canid remains dating to the late Upper Pleistocene from across Beringia and southern Siberia, many of which are suggested to be Paleolithic dogs (see Germonpre et al. 2017 for a review of the Western Beringian and Siberian specimens)
. These include canids from
Ulakhan Sular (c. 17,200 kya), Dyuktai Cave (c. 17,300-14,100 kya), Afontova Gora-1 (c. 16,900 kya), Verholenskaya Gora (c. 14,900 kya), Berelekh (c. 14,100 kya), Little John (c. 14,000 kya; Easton et al. 2011), McDonald Creek (c. 14,000-12,600 kya; Mueller et al. 2015), Nikita Lake (c. 13,800 kya), Ushki-I (c. 12,800 kya), and Ust’Khaita (c. 12,300 kya).
At present, the taxonomy and interpretation of m any of these specimens is contested or inconclusive. Others have yet to be evaluated furthe 0015世界@名無史さん垢版2018/07/16(月) 21:27:05.540>>13
Koster dog F2256 dates to 8790 ± 30 BP (10,110-9,680 cal BP), Koster dog F2357 dates to 8820 ± 30 BP (10,130-9,700 cal BP), and the Stilwell II dog dates to 8840 ± 80 BP (10,190-9,630 cal BP)
. The chronological differences between the Stilwell II and Koster individuals are not statistically significant at the scale of 14C dating. These new dates range several hundred years earlier than previously -associated dates for the Koster dogs, and add another Lower Illinois River Valley dog to the early pre-contact dog record. 0016世界@名無史さん垢版2018/07/17(火) 23:32:31.320https://en.wikipedia.org/wiki/Jiroft_culture
A "Jiroft culture"[1] has been postulated as an early Bronze Age (late 3rd millennium BC) archaeological culture, located in the territory of present-day Balochistan and Kerm?n Provinces of Iran.
The hypothesis is based on a collection of artifacts that were confiscated in Iran and accepted by many to have derived from the Jiroft area in south central Iran, reported by online Iranian news services, beginning in 2001.
The proposed type site is Konar Sandal, near Jiroft in the Halil River area. Other significant sites associated with the culture include; Shahr-e Sukhteh (Burnt City), Tepe Bampur, Espiedej, Shahdad, Tal-i-Iblis and Tepe Yahya.
・Metallurgy In Period IVB (3100-2700 B.C.), a copper-bronze dagger was found which contained 3.0% tin, seemingly representing an alloy of tin. This is a very early evidence for copper-tin alloying in southwestern Asia. A related site is Tal-i Iblis, where early metallurgy has also been attested.[13]
・Early writing To Period IVC belong six proto-Elamite tablets that have been recovered. Also, eighty-four tablet blanks indicate that writing was being practised at Yahya. These finds are similar to the discoveries at Susa Cb and Sialk IV.[14][15]
・Also, an object was found similar to a writing stylus.[16] Konar Sandal is located 55 miles north of Yahya and is culturally similar. Both cities traded with Mesopotamia. According to archaeologist Massimo Vidale, Indus civilization weights, seals, and etched carnelian beads were found in the area, demonstrating the connections between these two cultures.[17] 0017世界@名無史さん垢版2018/07/22(日) 23:16:25.190 【人類学】縄文人、ラオス・マレーシアにルーツ? ゲノム配列解読[07/11] https://egg.5ch.net/test/read.cgi/scienceplus/1531460749/28
The human occupation history of Southeast Asia (SEA) remains heavily debated. Current evidence suggests that SEA was occupied by Hoabinhian hunter-gatherers until ~4000 years ago, when farming economies developed and expanded, restricting foraging groups to remote habitats. Some argue that agricultural development was indigenous; others favor the “two-layer” hypothesis that posits a southward expansion of farmers giving rise to present-day Southeast Asian genetic diversity. By sequencing 26 ancient human genomes (25 from SEA, 1 Japanese J?mon), we show that neither interpretation fits the complexity of Southeast Asian history: Both Hoabinhian hunter-gatherers and East Asian farmers contributed to current Southeast Asian diversity, with further migrations affecting island SEA and Vietnam. Our results help resolve one of the long-standing controversies in Southeast Asian prehistory. 0018世界@名無史さん垢版2018/07/22(日) 23:25:56.850>>17
Ancient Genomics Reveals Four Prehistoric Migration Waves into Southeast Asia
Two distinct population models have been put forward to explain present-day human diversity in Southeast Asia. The first model proposes long-term continuity (Regional Continuity model) while the other suggests two waves of dispersal (Two Layer model). Here, we use whole-genome capture in combination with shotgun sequencing to generate 25 ancient human genome sequences from mainland and island Southeast Asia, and directly test the two competing hypotheses.
We find that early genomes from Hoabinhian hunter-gatherer contexts in Laos and Malaysia have genetic affinities with the Onge hunter-gatherers from the Andaman Islands, while Southeast Asian Neolithic farmers have a distinct East Asian genomic ancestry related to present-day Austroasiatic-speaking populations.
We also identify two further migratory events, consistent with the expansion of speakers of Austronesian languages into Island Southeast Asia ca. 4 kya, and the expansion by East Asians into northern Vietnam ca. 2 kya.
These findings support the Two Layer model for the early peopling of Southeast Asia and highlight the complexities of dispersal patterns from East Asia. 0019世界@名無史さん垢版2018/08/21(火) 20:22:21.460 ●キリスト教のカルト教義「聖絶」とは何か●
