Q haplogroup of Y chromosome pushes American settlement to before 18,000 years BP

Another paper suggests an early peopling of America: Human Y chromosome sequences from Q Haplogroup reveal a South American settlement pre-18,000 years ago and a profound genomic impact during the Younger Dryas, Paula B. Paz Sepúlveda et al. ,Andrea Constanza Mayordomo,Camila Sala,Ezequiel Jorge Sosa,Jonathan Javier Zaiat,Mariela Cuello,Marisol Schwab,Daniela Rodríguez Golpe,Published: August 17, 2022 https://doi.org/10.1371/journal.pone.0271971.

This is one of a growing trend that supports an early arrival of human beings to America, in this case before 18,000 years BP.

The abstract states: "The present is the first genomic study of Q Haplogroup in which current knowledge on Q-M848 sub-lineages is contrasted with the historical, archaeological and linguistic data available. The divergence times, spatial structure and the SNPs found here as novel for Q-Z780, a less frequent sub-haplogroup autochthonous of the Americas, provide genetic support for a South American settlement before 18,000 years ago.

I foung it intersting that Argentine men of Native American origin shared a sub-linage with men from Sri Lanka! : "One of the new Argentine samples sequenced in this study, from San Juan (RUTBE), is presented as a sub-lineage of Q-F4674 along with 2 other Sri Lankan samples from the databases (S5 Fig and S1 Table). In turn, San Juan’s sample shares Q-Z36057 with 1 of Sri Lanka’s individuals; the age of this lineage has not been yet estimated. The occurrence of Q-F4674 in the Americas has recently been found and published by our group".

Below is the treee, the green asterisk marks dated lineages, notice how old this one is! and the Peruvian one almost 24 Ky old. But the paper didn't analyze it.

A site dated at 37,000 years ago in the Colorado Plateau!

An interesting title for a new paper: Human Occupation of the North American Colorado Plateau ∼37,000 Years Ago by Timothy Rowe et al. (Front. Ecol. Evol., 07 July 2022, Sec. Paleontology https://doi.org/10.3389/fevo.2022.903795).

The abstract gives this very ancient site an age of 38,900–36,250 cal BP and 37,000 years ago is well before the 15Ky usually accepted by the Out of Beringia theory that is mainstream orthodoxy regarding the peopling of America!:

" Calibrating human population dispersals across Earth’s surface is fundamental to assessing rates and timing of anthropogenic impacts and distinguishing ecological phenomena influenced by humans from those that were not. Here, we describe the Hartley mammoth locality, which dates to 38,900–36,250 cal BP by AMS 14C analysis of hydroxyproline from bone collagen. We accept the standard view that elaborate stone technology of the Eurasian Upper Paleolithic was introduced into the Americas by arrival of the Native American clade ∼16,000 cal BP. It follows that if older cultural sites exist in the Americas, they might only be diagnosed using nuanced taphonomic approaches. We employed computed tomography (CT and μCT) and other state-of-the-art methods that had not previously been applied to investigating ancient American sites. This revealed multiple lines of taphonomic evidence suggesting that two mammoths were butchered using expedient lithic and bone technology, along with evidence diagnostic of controlled (domestic) fire. That this may be an ancient cultural site is corroborated by independent genetic evidence of two founding populations for humans in the Americas, which has already raised the possibility of a dispersal into the Americas by people of East Asian ancestry that preceded the Native American clade by millennia. The Hartley mammoth locality thus provides a new deep point of chronologic reference for occupation of the Americas and the attainment by humans of a near-global distribution. "

Slowly but surely evidence is supporting the notion of an ancient peopling of America.
