Around 316,000 western lowland gorillas are thought to exist in the wild, [101] 4,000 in zoos, thanks to conservation; eastern lowland gorillas have a population of under 5,000 in the wild and 24 in zoos. Mountain gorillas are the most severely endangered, with an estimated population of about 880 left in the wild and none in zoos.

The mountain gorilla (Gorilla beringei beringei) is one of the two subspecies of the eastern gorilla.It is listed as endangered by the IUCN as of 2018. [2]There are two populations: One is found in the Virunga volcanic mountains of Central/East Africa, within three National Parks: Mgahinga, in southwest Uganda; Volcanoes, in northwest Rwanda; and Virunga, in the eastern Democratic Republic of ...
The gorilla–human last common ancestor (GHLCA, GLCA, or G/H LCA) is the last species that the tribes Hominini and Gorillini (i.e. the chimpanzee–human last common ancestor on one hand and gorillas on the other) share as a common ancestor. It is estimated to have lived (T GHLCA) during the late Miocene. [1] [2] [3] [4]
Western gorillas are long-lived and may survive for as long as 40 years in the wild. A group's home range may be as large as 30 km 2 (12 sq mi), but is not actively defended. Wild western gorillas are known to use tools. [10] Western gorillas' diets are high in fiber, including leaves, stems, fruit, piths, flowers, bark, invertebrates, and soil.
At long irregular intervals, Earth's biosphere suffers a catastrophic die-off, a mass extinction, [9] often comprising an accumulation of smaller extinction events over a relatively brief period. [10] The first known mass extinction was the Great Oxidation Event 2.4 billion years ago, which killed most of the planet's obligate anaerobes.
Newborn gorillas are typically smaller than full-term human babies, and at 2.2 kilograms (4.85 pounds), Kaius seemed to be doing well – until Kisane, a giant compared to his tiny newborn, took ...
Primate habitats span a range of altitudes: the black snub-nosed monkey has been found living in the Hengduan Mountains at altitudes of 4,700 meters (15,400 ft), [195] the mountain gorilla can be found at 4,200 meters (13,200 ft) crossing the Virunga Mountains, [196] and the gelada has been found at elevations of up to 5,000 m (16,000 ft) in ...
