Which animal is an intelligent ape?
Chimpanzees are highly intelligent and are able to solve many kinds of problems posed to them by human trainers and experimenters. A number of researchers have taught chimpanzees to use sign language or languages based on the display of tokens or pictorial symbols.
Which primates are arboreal Quadrupedalism?
The African apes utilize terrestrial quadrupedalism with fingers folded at the first joint (knuckle-walking), and exhibiting longer arms than legs and a back angled at 45 degrees. Orangutans move with a fist-walking hand posture (fingers entirely closed in a fist) and often highly supinated foot positions.
Why are primates arboreal?
This arboreal heritage of primates has resulted in adaptations that include, but are not limited to: 1) a rotating shoulder joint; 2) a big toe that is widely separated from the other toes and thumbs, that are widely separated from fingers (except humans), which allow for gripping branches; and 3) stereoscopic vision.

Chimpanzees are both terrestrial and arboreal, with the amount of time spent on the ground varying between study sites and between sexes (Doran 1996). All chimpanzees build sleeping nests in trees at night (Rowe 1996).
Are gorillas or chimps smarter?
PALO ALTO, Calif., June 26—Experiments with a captive gorilla here suggest that gorillas, long considered less intelligent than chimpanzees, may prove to be their intellectual rivals.

After ranking 24 evolutionarily diverse primate genera, he found that very few of them did well on one task and particularly badly on another. Some genera just prove more capable overall. The great apes, not unexpectedly, cluster at the top, while groups that evolved earlier, like lemurs, cluster at the bottom.
Are primates terrestrial or arboreal?
Most primate species stay a minimum of partly arboreal, and even terrestrial (ground-living) primates retain diversifications for climbing timber. Taxonomic charts of the dwelling primates could be discovered under.
What is the hierarchy of primate intelligence?

What are the characteristics of primates?
Primates are thought of as generalist mammals. Different types of primates have a skeletal construction that enables a large range of movement of the limbs. This is mirrored within the variety of ways in which they transfer round. They could leap, climb, brachiate (swing from branch to branch), stroll on all 4 legs, or stroll on two legs.
