The timing of the first human migration into the Americas and its relation to the appearance of the Clovis technological complex in North America at about 11,000 to 10,800 radiocarbon years before the present (14C years B.P.) remains contentious. We establish that humans were present at Paisley 5 Mile Point Caves, in south-central Oregon, by 12,300 14C years B.P., through the recovery of human mitochondrial DNA (mtDNA) from coprolites, directly dated by accelerator mass spectrometry. The mtDNA… 
Comment on “DNA from Pre-Clovis Human Coprolites in Oregon, North America”
DNA from radiocarbon-dated paleofecal remains from Paisley Cave, Oregon, which ostensibly demonstrate a human presence in North America predating the well-established Clovis complex are questioned.
Comment on “DNA from Pre-Clovis Human Coprolites in Oregon, North America”
Results of the micromorphological and Fourier transform infrared spectroscopy analyses of one of the reported coprolites are difficult to reconcile with the DNA results identifying the coprolite as human.
Pre-Clovis Mastodon Hunting 13,800 Years Ago at the Manis Site, Washington
The tip of a projectile point made of mastodon bone is embedded in a rib of a single disarticulated mastodon at the Manis site in the state of Washington, providing evidence that people were hunting proboscideans at least two millennia before Clovis.
Dietary Items in Early to Late Holocene Human Coprolites from Paisley Caves, Oregon, USA
ABSTRACT This study describes the results of palynological, macrobotanical, and microfaunal investigations of 19 coprolites from the Paisley Five Mile Point Caves locality (35LK3400) situated in

This research focused particularly on demonstrating that the radiocarbon dates of the initial peopling of the Americas are accurate and that the coprolites have been properly dated.
Ancient DNA: Muddy messages about American migration
A series of environmental reconstructions based on coring of lake sediments in what was once the ice-free corridor between Siberia and Laurentide indicate that the corridor would have still been inhospitable even after humans are known to have arrived in the Americas south of the ice.
The Paleo-Indian Entry into South America According to Mitogenomes
Coalescence age estimates for these subhaplogroups provide time boundaries indicating that early Paleo‐Indians probably moved from North America to the area corresponding to modern Ecuador and Peru over the short time frame of ˜1.0 and 14.6 ka'.
Response to Comment by Goldberg et al. on “DNA from Pre-Clovis Human Coprolites in Oregon, North America”
It is argued that the diagnostic capability of the techniques used by Goldberg et al. are limited, and new genetic data is presented that support their original claims.


Beringian Standstill and Spread of Native American Founders
The newly resolved phylogenetic structure suggests that ancestors of Native Americans paused when they reached Beringia, during which time New World founder lineages differentiated from their Asian sister-clades, and a swift migration southward that distributed the founder types all the way to South America.
Mitochondrial DNA studies of Native Americans: Conceptions and misconceptions of the population prehistory of the Americas
A decade ago, the first reviews of the collective mitochondrial DNA data from Native Americans concluded that the Americas were peopled through multiple migrations from different Asian populations beginning more than 30,000 years ago, and molecular biology made a significant contribution to the study of American prehistory.
Ancient DNA chronology within sediment deposits: are paleobiological reconstructions possible and is DNA leaching a factor?
It is indicated that DNA from sediments can still offer a rich source of information on past environments, provided that the risk from vertical migration can be controlled for and that physical remains of organisms or their ejecta need to have been incorporated in the sediments for their DNA to be detected.
Spatial gradients in Clovis-age radiocarbon dates across North America suggest rapid colonization from the north
The results suggest that the Clovis-age archaeological record represents a rapid demic colonization event originating from the north, and it is shown that the high velocity of this wave can be accounted for by a combination of demographic processes, habitat preferences, and mobility biases across complex landscapes.
Review Paper. Ancient DNA
Initial results have revealed surprisingly complex population histories, and indicate that modern phylogeographic studies may give misleading impressions about even the recent evolutionary past.
Chronology of latest Pleistocene lake‐level fluctuations in the pluvial Lake Chewaucan basin, Oregon, USA
New accelerator mass spectrometer radiocarbon ages from gastropods in shore deposits within the pluvial Lake Chewaucan basin, combined with stratigraphical and geomorphological evidence, identify an
Crosslinks Rather Than Strand Breaks Determine Access to Ancient DNA Sequences From Frozen Sediments
The results question the reliability of the commonly used models relying on depurination kinetics for predicting the long-term survival of DNA under permafrost conditions and suggest that new strategies for repair of ancient DNA must be considered if the yield of amplifiable DNA from permaf frost sediments is to be significantly increased.

Intcal04 Terrestrial Radiocarbon Age Calibration, 0–26 Cal Kyr BP
A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace IntCal98, which extended from 0–24 cal kyr BP
