Female chimps learn to fish for termites earlier and better than the young males. [40] Females also spend more time fishing while at the mounds with their mothers—males spend more time playing. When they are adults, females need more termite protein because with young to care for, they cannot hunt the way males can.
The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes).

Gene duplications account for most of the sequence differences between humans and chimps. Single-base-pair substitutions account for about half as much genetic change as does gene duplication. Typical human and chimpanzee homologs of proteins differ in only an average of two amino acids. About 30 percent of all human proteins are identical in ...
Humans have a far faster and more accurate throw than other animals. [172] Humans are also among the best long-distance runners in the animal kingdom, but slower over short distances. [173] [161] Humans' thinner body hair and more productive sweat glands help avoid heat exhaustion while running for long distances. [174]
The Missouri Primate Foundation took in adult chimps previously sold as pets or retired from show business. In 2001, a 28-year-old chimp named Suzy escaped and was shot and killed by Jason Coats, a 17-year-old who lived next door. [11] [13] Connie Casey took out a newspaper ad to "Make sure Suzy's killer is punished!" Coats was charged with ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.

A mammal (from Latin mamma 'breast') [1] is a vertebrate animal of the class Mammalia (/ m ə ˈ m eɪ l i. ə /).Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones.
The decline of wild mammal populations globally has been an occurrence spanning over the past 50,000 years, at the same time as the populations of humans and livestock have increased. Nowadays, the total biomass of wild mammals on land is believed to be seven times lower than its prehistoric values, while the biomass of marine mammals had ...
