Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. [1] It is an extension of the conservation practice of rewilding , which aims to restore functioning, self-sustaining ecosystems through practices that may include species reintroductions.
Pleistocene rewilding is the (re)introduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna, to restore ecosystem function. Advocates of the approach maintain that ecosystems where species evolved in response to Pleistocene megafauna but now lack large mammals may be in danger of collapse .
The Bolson tortoise was recently brought to the world's attention when, in August 2005 an, article on Pleistocene rewilding appeared in the journal Nature (Donlan, et al., 2005) proposing that megafauna that became extinct in North America at the close of the Pleistocene (~12,800 years ago) be reintroduced to the continent to create a ...
For example, megaherbivores thrived in Pleistocene Siberia, which had and has a more continental climate than Pleistocene or modern (post-Pleistocene, interglacial) North America. [ 200 ] [ 201 ] [ 202 ] The animals that became extinct actually should have prospered during the shift from mixed woodland-parkland to prairie, because their primary ...
Paul Martin at Rampart Cave, home of the Shasta ground sloth in Grand Canyon, ca. 1975. Paul Schultz Martin (born in Allentown, Pennsylvania in 1928, died in Tucson, Arizona September 13, 2010) [1] [2] was an American geoscientist at the University of Arizona who developed the theory that the Pleistocene extinction of large mammals worldwide was caused by overhunting by humans.

The Pyrenean ibex, also known as the bouquetin (French) and bucardo (Spanish), is the only animal to have survived de-extinction past birth through cloning.. De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct species. [1]
The wood-pasture hypothesis (also known as the Vera hypothesis and the megaherbivore theory) is a scientific hypothesis positing that open and semi-open pastures and wood-pastures formed the predominant type of landscape in post-glacial temperate Europe, rather than the common belief of primeval forests.
The Pleistocene (/ ˈ p l aɪ s t ə ˌ s iː n,-s t oʊ-/ PLY-stə-seen, -stoh-; [4] [5] referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
