Our analysis of the sample yielded the first-ever complete ancient mitochondrial genome for (E. dorsatum) and only the second full mitogenome for the species. Its Holocene age is considerably younger than the Pleistocene megafauna typically recovered in the Yukon permafrost, demonstrating the potential for these deposits to preserve specimens from interglacial periods. Crucially, this finding confirms the presence of porcupines in the region 3000 years ago, in line with the hypothesis that this species only dispersed into Yukon and Alaska following the establishment of boreal forests after the Last Glacial Period.", "doi": "10.1038/s41598-026-44540-2", "pmid": "41845022", "labels": {"National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics

Obtaining genomic data from this period is challenging, but mitochondrial DNA, given its higher abundance compared to nuclear DNA, could play an important role to understand evolutionary processes at this time scale. In this study, we report 34 new mitogenomes, including two EP and nine MP mammoth (Mammuthus spp.) specimens from Siberia and North America and analyze them jointly with >200 publicly available mitogenomes to reconstruct a transect of mammoth mitogenome diversity throughout the last million years. We find that our EP mitogenomes fall outside the diversity of all Late Pleistocene (LP) mammoths, while those derived from MP mammoths are basal to LP mammoth Clades 2 and 3, supporting an ancient Siberian origin of these lineages. In contrast, the geographical origin of Clade 1 remains unresolved. With these new deep-time mitogenomes, we observe diversification events across all clades that appear consistent with previously hypothesized MP and LP demographic changes. Furthermore, we improve upon an existing methodology for molecular clock dating of specimens >50 ka, demonstrating that specimens need to be individually dated to avoid biases in their age estimates. Both the molecular and analytical improvements presented here highlight the importance of deep-time genomic data to discover long-lost genetic diversity, enabling better assessments of evolutionary histories.", "doi": "10.1093/molbev/msaf065", "pmid": "40202893", "labels": {"Bioinformatics (NBIS)": "Service", "Bioinformatics Support, Infrastructure and Training": "Service", "Bioinformatics Support and Infrastructure": "Service", "National Genomics Infrastructure": "Service", "NGI Stockholm (Genomics Production)": "Service", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC11980863"}, {"db": "pii", "key": "8107989"}], "notes": [], "created": "2025-05-05T12:32:34.796Z", "modified": "2025-11-28T10:49:58.497Z"}]}
