Patricia Wright of Stoney Brook University explains why owl monkeys are devoted fathers and nocturnal.
A monkey is a long-tailed, medium-sized member of the order of Primates. The primate order also includes macaques, baboons, guenons, capuchins, marmosets, and tamarins.Monkeys today are a member of two of the three groups of simian primates, the New World monkeys and the Old World monkeys, of which there are 264 known species. Apes and chimpanzees are not scientifically classified as monkeys, a common misconception due to their physical similarities.Some distinguishing features between New World and Old World monkeys include the tail. Most New World monkeys have prehensile tails while Old World monkeys do not. The facial features of each group of monkeys also differ substantially; however, there are a number of shared features as well.Monkeys are a very diverse family of species, ranging in size from the 5-6 inch Pygmy Marmoset, to the adult male Mandrill, which can be 3 feet tall. Some monkeys spend the majority if their lives in treetops, while others call savannas and grasslands home. Most monkeys survive of a diet of fruit, leaves, nuts, berries, eggs, insects and they occasionally hunt other smaller animals.
A vaccine against Ebola virus that uses so-called virus-like particles instead of live, infectious virus triggers promising immune reactions in laboratory chimpanzees, researchers say.
Chimpanzees not only possess many of the same personality traits as humans — from agreeableness to extroversion — these traits are structured almost identically in both humans and chimps.
Monkeys can use symbols to add, which sheds light on the evolutionary origins of math, researchers say.
Bonobos have a reputation among the great apes as "hippie chimps," and new research hints that hormones may be a key element in keeping the animals' aggression in check.
A tiny primate fossil discovered in Asia could shed light on the period when ancient human ancestors migrated from Asia to Africa, researchers say.
The fossilized jaw of a pint-size primate that lived about 35 million years ago in Asia has been unearthed in Thai coal mines.
A weird ancient ape that lived between 7 million and 9 million years ago walked on all fours, new research suggests. The findings overturn previous research suggesting the ape walked upright.
Certain characteristics shared by humans and chimps may have allowed them to incorporate medicines into their societies.
