This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically shorter than placental.
Hominidae (great ape ancestors) speciate from the ancestors of the gibbon (lesser apes) between c. 20 to 16 Ma. They largely reduced their ancestral snout and lost the uricase enzyme (present in most organisms). [28] 16-12 Ma Homininae ancestors speciate from the ancestors of the orangutan between c. 18 to 14 Ma. [29]
c. 18–12 Ma – estimated age of the Hominidae/Hylobatidae (great apes vs. gibbons) split. c. 16 Ma – The hippopotamus evolves. c. 15 Ma – First mastodons, bovids, and kangaroos. Australian megafauna diversify. c. 11 Ma – Estimated date for the origin of the modern Yangtze river. c. 10 Ma – Insects diversify. First large horses.
A marsupial has a short gestation period, typically shorter than its estrous cycle, and gives birth to an underdeveloped newborn that then undergoes further development; in many species, this takes place within a pouch-like sac, the marsupium, located in the front of the mother's abdomen.
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 ...
An ancient species of great ape was likely driven to extinction hundreds of thousands of years ago when climate change put their favorite fruits out of reach during dry seasons, scientists ...
A 2014 whole-genome molecular dating analysis indicated that the gibbon lineage diverged from that of great apes (Hominidae) around 17 million years ago (16.8 ± 0.9 Mya), based on certain assumptions about the generation time and mutation rate. [1] The extinct Bunopithecus sericus was a gibbon or gibbon-like ape. [3]
Standing at 9 feet tall and weighing up to 660 pounds, Gigantopithecus blacki was the largest primate to walk the Earth. The giant ape — an herbivore with a fondness for fruit — appeared in ...
