Elephantidae is a family of large, herbivorous proboscidean mammals which includes the living elephants (belonging to the genera Elephas and Loxodonta), as well as a number of extinct genera like Mammuthus (mammoths) and Palaeoloxodon. They are large terrestrial mammals with a snout modified into a trunk and teeth modified into tusks.
Mammoths are distinguished from living elephants by their (typically large) spirally twisted tusks and in at least some later species, the development of numerous adaptions to living in cold environments, including a thick layer of fur. Mammoths and Asian elephants are more closely related to each other than they are to African elephants.
[9] [10] [11] Mammoths (Mammuthus) are nested within living elephants as they are more closely related to Asian elephants than to African elephants. [12] Another extinct genus of elephant, Palaeoloxodon , is also recognised, which appears to have close affinities with African elephants and to have hybridised with African forest elephants. [ 13 ]
The report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of all the Earth's species with extinction even in the absence of the other four factors, while if the warming reached 4.3 °C (7.7 °F), 16% of the Earth's species would be threatened with extinction.
Commenting on whether the woolly mammoth should be brought back to life, Lynch says, "I personally think no. Mammoths are extinct and the environment in which they lived has changed. There are ...
There are approximately 415,000 African elephants left in the world. The World Wildlife Foundation said that, in 2016, experts estimated their population had fallen by 111,000 over the course of a ...
For fungi, it estimated that 9.4% are threatened due to climate change, while 62% are threatened by other forms of habitat loss. [43] 2024 review paper projected likely extinctions of 8% to 16% plant species as well as 8%–27% fungi species under RCP4.5 by 2070. Under RCP8.5 23% to 31% of both plant and fungi species would be lost. [44]
The effort to regrow a woolly mammoth from the edited genes of an Asian elephant took a petri dish-sized move toward reality. De-extinction company Colossal Biosciences announced they can now ...
