A 2019 study found that the species was "smaller than previously thought" and about the size of a gibbon. [5] It is unknown whether GHLCA was tailless and had a broad, flat rib cage like their descendants. [6]: 193 But it is likely that it was a small animal, probably weighing only 12 kilograms (26 lb). This contradicts previous theories that ...
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
The whole genome of the gibbons in Southeast Asia was first sequenced in 2014 by the German Primate Center, including Christian Roos, Markus Brameier, and Lutz Walter, along with other international researchers. One of the gibbons that had its genome sequenced is a white-cheeked gibbon (Nomascus leucogenys, NLE) named Asia.
A hominoid, sometimes called an ape, is a member of the superfamily Hominoidea: extant members are the gibbons (lesser apes, family Hylobatidae) and the hominids. A hominid is a member of the family Hominidae, the great apes: orangutans, gorillas, chimpanzees and humans.
The gibbons (family Hylobatidae) and orangutans (genus Pongo) are the first groups to split from the line leading to the hominins, including humans, then gorillas (genus Gorilla), and finally chimpanzees and bonobos (genus Pan). The splitting date between hominin and chimpanzee lineages is placed by some between 4 and 8 million years ago, that ...
An archaic survivor from this stage is the acorn worm, sporting an open circulatory system (with less branched blood vessels) with a heart that also functions as a kidney. Acorn worms have a plexus concentrated into both dorsal and ventral nerve cords. The dorsal cord reaches into the proboscis, and is partially separated from the epidermis in ...
The Hominini (hominins) form a taxonomic tribe of the subfamily Homininae (hominines). They comprise two extant genera: Homo and Pan (chimpanzees and bonobos), and in standard usage exclude the genus Gorilla (), which is grouped separately within the subfamily Homininae.
John Heysham Gibbon (September 29, 1903 – February 5, 1973) was an American surgeon best known for inventing the heart–lung machine and performing subsequent open-heart surgeries which revolutionized heart surgery in the twentieth century.
