Ancient DNA and spatial modeling reveal a pre-Inca trans-Andean parrot trade [PDF]
Nature CommunicationsVibrant feathers from Amazonian parrots were among the most prestigious symbols of status in the pre-Hispanic Andes, yet their acquisition required traversing the formidable Andean mountain range.

Cold Spring Harbor Perspectives in Biology, 2013 Under favorable conditions DNA can survive for thousands of years in the remains of dead organisms. The DNA extracted from such remains is invariably degraded to a small average size by processes that at least partly involve depurination. It also contains large amounts of deaminated cytosine residues that are accumulated toward the ends of the ...

Collapse of the mammoth-steppe in central Yukon as revealed by ancient environmental DNA
Nature Communications, 2021 ‘The timing and ecological dynamics of extinction in the late Pleistocene are not well understood. Here, the authors use sediment ancient DNA from permafrost cores to reconstruct the paleoecology of the central Yukon, finding a substantial turnover in ...

Human Pangenomics: Promises and Challenges of a Distributed Genomic Reference
Life, 2023 A pangenome is a collection of the common and unique genomes that are present in a given species. It combines the genetic information of all the genomes sampled, resulting in a large and diverse range of genetic material.

Assessing alignment-based taxonomic classification of ancient microbial DNA [PDF]
PeerJ, 2019 The field of palaeomicrobiology—the study of ancient microorganisms—is rapidly growing due to recent methodological and technological advancements. It is now possible to obtain vast quantities of DNA data from ancient specimens in a high-throughput ...

Epigenetics of Ancient DNA [PDF]
Acta Naturae, 2016 Initially, the study of DNA isolated from ancient specimens had been based on the analysis of the primary nucleotide sequence. This approach has allowed researchers to study the evolutionary changes that occur in different populations and determine the influence of the environment on genetic selection.
