Athena Review 3 2 Main Index Ancient Peopling Of The Americas Several hundred thousand pieces of stone, bone, ivory, and teeth from gault can be attributed to the clovis interval (11,200 10,900 rcya; 12,900 12,550 cal bp). most are debris from stone tool manufacture, but a diverse array of tools (figs.3,4) occurs as well, along with bones of several kinds of animals. Before the advent of genomics, genetic evidence for the peopling of the americas relied on studies of mitochondrial dna (mtdna) 1,2,3,4,5,6,7 and the non recombining portion of the y chromosome 8. There are currently several models of the peopling process differing with respect to timing, routes, and affiliation with modern (and ancient) populations in asia and the americas . one perspective that has become prominent in the last decade is of an early entry (~25,000 to 15,000 years ago) into the americas via a pacific coastal migration. Abstract. in less than a decade, analyses of ancient genomes have transformed our understanding of the indigenous peopling and population history of the americas. these studies have shown that this history, which began in the late pleistocene epoch and continued episodically into the holocene epoch, was far more complex than previously thought.

A notable corollary to the peopling process is seen in the genetic his tory of dogs, which were possibly domesticated in siberia or beringia in the late pleistocene, and show mtdna lineage splits from there and into the americas that roughly coincide with the major splits within the dispersing human populations79. A close up of both archaeological sites and locations for geological and paleogenetic samples, including lake bed sediments, ancient plants and other material that has helped researchers build a more complete picture of the peopling of the americas. the most likely overland route, between the laurentide and cordilleran ice sheets, is on left.
