What Killed the Woolly Mammoth?
0659 Forty-two thousand years ago, during the last glacial advance of the Pleistocene epoch, woolly mammoths thundered across the frozen steppes of the Eurasian continent. The huge beasts thrived on the arid tundra of the last ice age, having adapted to temperatures that would chill the toes off any hairless ape. Yet, by the middle of the Holocene epoch, 6,000 years ago, the glaciers had retrea...
متن کاملClimate Change, Humans, and the Extinction of the Woolly Mammoth
Woolly mammoths inhabited Eurasia and North America from late Middle Pleistocene (300 ky BP [300,000 years before present]), surviving through different climatic cycles until they vanished in the Holocene (3.6 ky BP). The debate about why the Late Quaternary extinctions occurred has centred upon environmental and human-induced effects, or a combination of both. However, testing these two hypoth...

متن کاملGenetic Structure and Extinction of the Woolly Mammoth, Mammuthus primigenius
The interval since circa 50 Ka has been a period of significant species extinctions among the large mammal fauna. However, the relative roles of an increasing human presence and a synchronous series of complex environmental changes in these extinctions have yet to be fully resolved. Recent analyses of fossil material from Beringia have clarified our understanding of the spatiotemporal pattern o...
متن کاملHolarctic 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 biogeographic histories difficult. Here, we analyse mitochondrial DNA (mtDNA) variation in the woolly mammoth from across its Holarctic range to reconstruct its history over the last 200 thousand years (kyr). W...
