Columbian mammoth
The Columbian mammoth (Mammuthus columbi) is an extinct species of mammoth that inhabited the Americas as far north as the Northern United States and as far south as Costa Rica during the Pleistocene epoch. The Columbian mammoth descended from mammoths that colonised North America around 1.5 million years ago, that later hybridised with woolly mammoths during the Middle Pleistocene, prior to 420,000 years ago. The Columbian mammoth was among the last mammoth species, and the pygmy mammoths evolved from them on the Channel Islands of California.
Pleistocene Park
Pleistocene Park (Pleystotsenovyy park) is a nature reserve on the Kolyma River south of Chersky in the Sakha Republic, Russia, in northeastern Siberia, where an attempt is being made to re-create the northern subarctic steppe grassland ecosystem that flourished in the area during the last glacial period. The project is being led by Russian scientists Sergey Zimov and Nikita Zimov, testing the hypothesis that repopulating with large herbivores (and predators) can restore rich grasslands ecosystems, as expected if overhunting, and not climate change, was primarily responsible for the extinction of wildlife and the disappearance of the grasslands at the end of the Pleistocene epoch.
Indian elephant
The Indian elephant (Elephas maximus indicus) is one of three extant recognised subspecies of the Asian elephant and native to mainland Asia. Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List as the wild population has declined by at least 50% since the 1930s to 1940s, i.e. three elephant generations. The Asian elephant is threatened by habitat loss, degradation and fragmentation. In general, Asian elephants are smaller than African elephants and have the highest body point on the head.
Insular dwarfism
Insular dwarfism, a form of phyletic dwarfism, is the process and condition of large animals evolving or having a reduced body size when their population's range is limited to a small environment, primarily islands. This natural process is distinct from the intentional creation of dwarf breeds, called dwarfing. This process has occurred many times throughout evolutionary history, with examples including dinosaurs, like Europasaurus and Magyarosaurus dacus, and modern animals such as elephants and their relatives.
Neogene
The Neogene (ˈniː.ədʒiːn , informally Upper Tertiary or Late Tertiary) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago (Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868).
