Y chromosome sequences reveal a short beringian standstill, rapid expansion, and early population structure of native american founders
The Americas were the last inhabitable continents to be occupied by humans, with a growing multidisciplinary consensus for entry 15–25 thousand years ago (kya) from northeast Asia via the former Beringia land bridge [1, 2, 3, 4]. Autosomal DNA analyses have dated the separation of Native American an...

The Americas were the last inhabitable continents to be occupied by humans, with a growing multidisciplinary consensus for entry 15–25 thousand years ago (kya) from northeast Asia via the former Beringia land bridge [1, 2, 3, 4]. Autosomal DNA analyses have dated the separation of Native American ancestors from the Asian gene pool to 23 kya or later [5, 6] and mtDNA analyses to ∼25 kya [7], followed by isolation (“Beringian Standstill” [8, 9]) for 2.4–9 ky and then a rapid expansion throughout the Americas. Here, we present a calibrated sequence-based analysis of 222 Native American and relevant Eurasian Y chromosomes (24 new) from haplogroups Q and C [10], with four major conclusions. First, we identify three to four independent lineages as autochthonous and likely founders: the major Q-M3 and rarer Q-CTS1780 present throughout the Americas, the very rare C3-MPB373 in South America, and possibly the C3-P39/Z30536 in North America.
