After evolving in Africa at the close of the Miocene, mammoths (Mammuthus sp.) spread through much of the northern hemisphere, diversifying morphologically as they entered various habitats. Paleontologically, these morphs are conventionally recognized as species. In Pleistocene North America alone, several mammoth species have been recognized, inhabiting environments as different as cold tundra-steppe in the north and the arid grasslands or temperate savanna-parklands of the south. Yet mammoth…

The evolutionary and phylogeographic history of woolly mammoths: a comprehensive mitogenomic analysis

The genetic results and the pattern of morphological variation in time and space suggest that male-mediated gene flow, rather than large-scale dispersals, was important in the Pleistocene evolutionary history of mammoths.

Late Pleistocene proboscidean population dynamics in the North American Midcontinent

Large-scale, collections-based, chronological and taphonomic analyses of midwestern Proboscidea suggest divergent population histories in mammoths and mastodons after the Last Glacial Maximum, suggesting this pattern is due to the collapse of trophic controls on proboscidean populations prior to the LGM and a subsequent system-wide shift from top-down to bottom-up regulatory mechanisms in Proboscidesa.

Central European Woolly Mammoth Population Dynamics: Insights from Late Pleistocene Mitochondrial Genomes

A high number of shared derived mutations between woolly mammoth mitochondrial clades are identified, questioning previous phylogenetic analysis and thus emphasizing the need for nuclear DNA studies to explicate the increasingly complex genetic history of the Woolly mammoth.

Comparative phylogeography of mainland and insular species of Neotropical molossid bats (Molossus)

It is shown that population structures within mastiff bats vary according to general habitat preferences, levels of population isolation, and historical fluctuations in climate, and that lineages on distant islands undergo genetic bottlenecks more frequently than island lineages closer to the mainland, which have a greater exchange of haplotypes.

A new genus of horse from Pleistocene North America

The palaeogenomic and morphometric analyses support the idea that there was only a single species of middle to late Pleistocene NWSL equid, and a new genus, Haringtonhippus, is proposed for the sole species H. francisci.

Lions and brown bears colonized North America in multiple synchronous waves of dispersal across the Bering Land Bridge

Stark synchronicity is revealed in the population dynamics of Beringian lions and brown bears, with multiple waves of dispersal across the Bering Land Bridge coinciding with glacial periods of low sea levels, as well as synchronous local extinctions in Eastern Beringia during Marine Isotope Stage 3.



Complete Columbian mammoth mitogenome suggests interbreeding with woolly mammoths

Though limited, the data suggest that the two species interbred at some point in their evolutionary histories, and the use of next-generation sequencing technologies holds promise in obtaining such data, even from non-cave, non-permafrost Pleistocene depositional contexts.

Out of America: Ancient DNA Evidence for a New World Origin of Late Quaternary Woolly Mammoths

Evolution and dispersal of mammoths across the Northern Hemisphere

A detailed look at mammoth fossils globally is taken and it is suggested that the North American Columbian mammoth, thought to have arisen from a European species, probably evolved from a more advanced Asian species.

Complete Mitochondrial Genome and Phylogeny of Pleistocene MammothMammuthus primigenius

It is demonstrated that well-preserved mitochondrial genome fragments, as long as ~1,600–1700 base pairs, can be retrieved from pre-Holocene remains of an extinct species, and the sequence of the complete mitochondrial genome is reported—the oldest mitochondrial genome sequence determined to date.

Proboscidean Mitogenomics: Chronology and Mode of Elephant Evolution Using Mastodon as Outgroup

The complete mitochondrial genome of the extinct American mastodon is sequenced from an Alaskan fossil that is between 50,000 and 130,000 y old, extending the age range of genomic analyses by almost a complete glacial cycle and concluding that the first sequence of mastodon DNA ever reported is obtained.

Ancient DNA reveals late survival of mammoth and horse in interior Alaska

The finding that mammoth and horse overlapped with humans for several millennia in the region where people initially entered the Americas challenges theories that megafaunal extinction occurred within centuries of human arrival or were due to an extraterrestrial impact in the late Pleistocene.

Holarctic genetic structure and range dynamics in the woolly mammoth

Ancient DNA analyses have provided enhanced resolution of population histories in many Pleistocene taxa. However, most studies are spatially restricted, making inference of species-level

Phylogenetic Position of Mammoth and Steller's Sea Cow Within Tethytheria Demonstrated by Mitochondrial DNA Sequences

DNA sequences from mitochondrial cytochrome b gene segments for the extinct woolly mammoth and Steller's sea cow and the extant Asian elephant and the Western Indian manatee allow us to construct the phylogeny for the Tethytheria.
