Yhteenvetoa Euroopan muinais-DNA:sta
Lähetetty: 17 Loka 2014 00:15Guardianissa on ollut vasta tälläinen artikkeli Euroopan muinais-DNA:sta. Lainasin tuohon alle keskeisia osia siitä. Ei sinänsä mitään aivan uutta, mutta yritys yhteenvetää tähänastisia tutkimuksia. Suomea ei mainita, mutta tässä foorumissa olleiden admixien ja muiden analyysien valossa suomalaisissa keskimäärin lienee Euroopan korkeimpia osuuksia metsästäjä-keräilijä-perimällä ja matalimpia viljelijä-perimällä. Miten lienee tuo pohjoisten euraasialaisten perimän (ANE) osuus suomalaisissa suhteessa muihin eurooppalaisiin?
DNA study reveals third group of ancient ancestors of modern Europeans
Mixture of hunter-gatherers and farmers was augmented by third wave of migrants, perhaps 5,000 years ago, from north Eurasia
”The findings suggest that the arrival of modern humans into Europe more than 40,000 years ago was followed by an influx of farmers some 8,000 years ago, with a third wave of migrants coming from north Eurasia perhaps 5,000 years ago. Others from the same population of north Eurasians took off towards the Americas and gave rise to Native Americans.
Modern Europeans are various mixes of the three populations. Sardinians are more than 80% early European farmer, with less than 1% of their genetic makeup coming from the ancient north Eurasians. In the Baltic states such as Estonia, some modern people are 50% hunter-gatherer and around a third early European farmer.
The modern English inherited around 50% of their genes from early European farmers, 36% from western European hunter-gatherers, and 14% from the ancient north Eurasians. According to the study, published in Nature, modern Scots can trace 40% of their DNA to the early European farmers and 43% to hunter-gatherers, though David Reich, a senior author on the study at Harvard University, said the differences were not significant.”
