Studies of the peopling Americas have focused on timing and number initial migrations. Less attention has been paid to subsequent spread people within Americas. We sequenced 15 ancient human genomes spanning from Alaska Patagonia; six are ≥10,000 years old (up ~18× coverage). All most closely related Native Americans, including those an Ancient Beringian individual two morphologically distinct "Paleoamericans." found evidence rapid dispersal early diversification that included previously...
Abstract Species determination based on genetic evidence is an indispensable tool in archaeology, forensics, ecology, and food authentication. Most available analytical approaches involve compromises with regard to the number of detectable species, high cost due low throughput, or a labor-intensive manual process. Here, we introduce “Species by Proteome INvestigation” (SPIN), shotgun proteomics workflow for analyzing archaeological bone capable querying over 150 mammalian species liquid...
The horse is central to many Indigenous cultures across the American Southwest and Great Plains. However, when how horses were first integrated into lifeways remain contentious, with extant models derived largely from colonial records. We conducted an interdisciplinary study of assemblage historic archaeological remains, integrating genomic, isotopic, radiocarbon, paleopathological evidence. Archaeological modern North show strong Iberian genetic affinities, later influx British sources, but...
Abstract Horses revolutionized human history with fast mobility 1 . However, the timeline between their domestication and widespread integration as a means of transport remains contentious 2–4 Here we assemble collection 475 ancient horse genomes to assess period when these animals were first reshaped by agency in Eurasia. We find that reproductive control modern domestic lineage emerged around 2200 bce , through close-kin mating shortened generation times. Reproductive following severe...
Significance The Siberian Arctic has witnessed numerous societal changes since the first known appearance of dogs in region ∼10,000 years ago. These include introduction ironworking ∼2,000 ago and emergence reindeer pastoralism ∼800 analysis 49 ancient dog genomes reveals that ancestry Siberia shifted over last 2,000 due to an influx from Eurasian Steppe Europe. Combined with genomic data humans archaeological evidence, our results suggest though human populations did not change this period,...
The contents of a pit located in the centre large communal structure at Asiab central Zagros mountains provides rare evidence for ritual food practices during Early Neolithic (~9660–9300 cal. bc ). This contained skulls least 19 wild boars carefully placed inside and subsequently sealed. Antler from red deer skull brown bear were also concealed within pit. included both male female animals varying age some larger canines deliberately removed. Such unique collection remains is unlikely to be...
The conservation and management of biological diversity rely heavily on clear definitions appropriate target units, such as populations, subspecies species. However, the nomenclature grey seal [Halichoerus grypus (Fabricius 1791)] has for many years been misled by two persistent assumptions; that there was no type specimen species locality lay in Greenland. Here, we describe a skull held collections Natural History Museum Denmark, present written morphological evidence to demonstrate this is...
Traditional methods for age determination of wildlife include either slicing thin sections off or grinding a tooth, both which are laborious and invasive. Especially when it comes to ancient valuable museum samples rare extinct species, non-invasive preferable. In this study, X-ray micro-computed tomography (µ-CT) was verified as an alternative method three species within the order Carnivora suborders Odontoceti. Teeth from 13 red foxes (Vulpes vulpes), 2 American mink (Neogale vison),...
Abstract Genetic species determination has become an indispensable tool in forensics, archaeology, ecology, and food authentication. The available methods are either suited for detecting a single taxon across many samples or screening wide range of few samples. Here, we introduce “Species by Proteome INvestigation” (SPIN), proteomics workflow capable querying over 150 mammalian 7.2 minutes mass spectrometry (MS) analysis. Streamlined automated sample preparation protein aggregation capture,...
Gyrfalcon (Falco rusticolus) is the largest falcon in world. It inhabits a wide range of climate zones Northern Hemisphere, from boreal forests south its to arid polar deserts High Arctic. In Greenland, because harsh, remote environments which gyrfalcons live, research related contemporary and pre-modern periods has been limited north-west, central west east coasts, with no specific investigations being conducted for north-east. Here, we report first record gyrfalcon north-east located at...
The analysis of the DNA entrapped in ancient shells molluscs has potential to shed light on evolution and ecology this very diverse phylum. Ancient genomics could help reconstruct responses past climate change, pollution, human subsistence practices at unprecedented temporal resolutions. Applications are however still their infancy, partly due our limited knowledge preservation calcium carbonate need for optimized methods responsible genomic data generation. To improve shell analyses, we...
There is an interest in using 3D scanning techniques the field of conservation and restoration (Acke et al. 2021). Many are already these for digitization research purposes, or reproductions objects does have some challenges when it comes to with shiny, transparent, dark surfaces (McMillion 2022, Motley 2021, Mubanga 2022). Hair, fur feathers may be difficult scan 2022), as well bones teeth, according experience authors. various methods help overcome this challenge, one being sprays AESUB...
Fluid preserved animal specimens in the collections of natural history museums constitute an invaluable archive past and present diversity. Well-preserved have a shelf-life spanning centuries are widely used for e.g. anatomical, taxonomical genetic studies. The way were collected depended on type historical setting. As many small mammals birds historically by shooting, large quantities heavy metal residues, primarily lead, may been introduced into sample form lead shot pellets. Over time,...
