† ^ denotes age at death, or, if living, age as of 24 January 2025 This list includes all some individuals to have reached the age of 60 years or more. The average lifespan of a chimpanzee is 40–50 years in the wild and 50-60 years in captivity. The 1 January will be given as the birthday to any individual whose exact birthdate isn't known ...
On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with shorter lifespans and faster growth rates benefit more from zoos than animals ...
They usually live less than 15 years, although individuals that reach 12 years may live an additional 15 years. On rare occasions, wild chimpanzees may live nearly 60 years. Captive chimpanzees tend to live longer than most wild ones, with median lifespans of 31.7 years for males and 38.7 years for females. [75]
Chimpanzees reach puberty between the age of eight and ten years. [39] A chimpanzee's testicles are unusually large for its body size, with a combined weight of about 4 oz (110 g) compared to a gorilla's 1 oz (28 g) or a human's 1.5 ounces (43 g).
Chimpanzees routinely live 30 years in captivity, and can reach 60 years of age. [27] Most of the labs either conduct or make the chimpanzees available for invasive research, [58] defined as "inoculation with an infectious agent, surgery or biopsy conducted for the sake of research and not for the sake of the chimpanzee, and/or drug testing."
The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
The clade currently represented by humans and the genus Pan (chimpanzees and bonobos) splits from the ancestors of the gorillas between c. 12 to 8 Ma. [31] 8-6 Ma Sahelanthropus tchadensis. Hominini: The latest common ancestor of humans and chimpanzees is estimated to have lived between
A mutation in the age−1 gene of the nematode worm Caenorhabditis elegans increased mean life span 65% and maximum life span 110%. [82] However, the degree of lifespan extension in relative terms by both the age-1 and daf-2 mutations is strongly dependent on ambient temperature, with ≈10% extension at 16 °C and 65% extension at 27 °C.
