what is population extinction? Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
What causes population extinction? The main direct causes of extinction are loss and degradation of habitats due to human use of land and sea; overexploitation of wild populations; and the impacts on populations and ecological communities of invasive alien species, pollution, and climate change14, 16 and 17.
When did the Deinotherium live? Deinotherium lived in Africa during the Early Miocene and through to the Early Pleistocene, from 20 – 2 million years ago.
Is Deinotherium an elephant? Deinotherium was a large elephant-like proboscidean that appeared in the Middle Miocene and survived until the Early Pleistocene. Although superficially resembling modern elephants, they had notably more flexible necks, limbs adapted to a more cursorial lifestyle as well as tusks that curved downwards and back.
