Summary

Order of Mammals:

  • Primates are a diverse order of mammals, divided into strepsirrhines (lemurs, galagos, and lorisids) and haplorhines (tarsiers and simians).

  • Primates evolved from small terrestrial mammals, adapting to life in trees with large brains, visual acuity, and dextrous hands.

  • There are 376-524 species of living primates, with new species still being discovered.

  • Primates have opposable thumbs and adaptations for climbing trees, including leaping and brachiation.

  • Primates are highly social and have slower rates of development, longer lifespans, and are known to use tools.

  • Close interactions between humans and non-human primates can lead to transmission of zoonotic diseases.

  • About 60% of primate species are threatened with extinction due to deforestation, primate hunting, and other factors.

  • Primates have traditionally been classified using an "ascending series" methodology, but modern classifications use monophyletic groupings.

  • The order Primates is part of the clade Euarchontoglires and is nested within the clade Eutheria of Class Mammalia.

  • The suborder Strepsirrhini split from the primitive primate line about 63 mya, while the suborder Haplorhini emerged about 40 mya.

  • The anthropoid primates possibly traversed the Atlantic Ocean from Africa to South America during the Eocene by island hopping.

  • Modern humans originated in Africa 100,000-200,000 years ago.The Anatomy, Physiology, and Behavior of Primates

  • The number of recognized primate species has increased from 376 in 2001 to 522 in recent publications, including subspecies.

  • Primate hybrids usually arise in captivity but have also been found in the wild, and intergeneric hybrids have been found.

  • The creation of two crab-eating macaque clones, Zhong Zhong and Hua Hua, was reported using the same complex DNA transfer method that produced Dolly the sheep.

  • The primate skull has a large, domed cranium that protects a large brain, with the mean endocranial volume being 1,201 cubic centimeters in humans.

  • Primates have forward-facing eyes on the front of the skull, which allows for binocular vision and accurate distance perception.

  • The primate collar bone is a prominent element of the pectoral girdle, allowing for broad mobility of the shoulder joint.

  • Sexual dimorphism is often exhibited in primates, with dimorphism in body mass and canine tooth size, along with pelage and skin color.

  • Primates have a variety of locomotion methods, including brachiation, bipedalism, leaping, arboreal, and terrestrial quadrupedalism, climbing, knuckle-walking, or a combination of these methods.

  • The evolution of color vision in primates is unique, with nocturnal primates often being monochromatic, catarrhines routinely trichromatic, and platyrrhines trichromatic in a few cases.

  • The social systems of primates are best classified by the amount of movement by females occurring between groups, with four categories proposed by Richard Wrangham based on this.

  • Several species of primates are known to associate in the wild and coordinate anti-predator behavior and foraging benefits.

  • Primates use olfactory signals, vocalizations, gestures, and facial expressions to convey psychological state, and they are a particularly vocal group of mammals, with some species making distinctive songs and choruses.Overview of Primates

  • Primates have a diverse range of vocalizations that are used for communication, territorial protection, and mate-guarding.

  • Many non-human primates have the vocal anatomy to produce human speech but lack the proper brain wiring.

  • Primates have slower rates of development than other mammals and rely on their mothers for care and feeding.

  • Infanticide is common in some species, particularly in polygynous species such as gray langurs and gorillas.

  • Primates have a longer juvenile period between weaning and sexual maturity than other mammals of similar size.

  • Primates exploit a variety of food sources, including fruit, leaves, gum, insects, and small vertebrates.

  • Predators of primates include various species of carnivorans, birds of prey, reptiles, and other primates.

  • Primates have advanced cognitive abilities and are capable of problem-solving, tool use, and understanding aspects of human language.

  • Some primates have been observed using tools in the wild, such as chimpanzees using sticks to fish for termites.

  • Primates live primarily in the tropical latitudes of Africa, Asia, and the Americas, but some species can be found outside of the tropics.

  • Close interactions between humans and non-human primates can create pathways for the transmission of zoonotic diseases.

  • The legal status of non-human primates is the subject of much debate, with some organizations campaigning to award them legal rights.The Threats to Non-Human Primates

  • The Great Ape Project recommends against using chimpanzees, orangutans and gorillas for animal experiments.

  • Around 15,000 non-human primates are kept as exotic pets in the US, with prices ranging from $3000 to $30,000.

  • Non-human primates are used in laboratories, space missions, and as service animals for disabled humans.

  • There are strict care requirements for non-human primates kept in captivity.

  • Over 60% of primate species are threatened with extinction, with 75% of species having decreasing populations.

  • Common threats to primate species include deforestation, forest fragmentation, monkey drives and primate hunting.

  • Large-scale tropical forest clearing is the main process that threatens primates.

  • Primates with a body size over 5kg are at increased extinction risk due to their greater profitability to poachers.

  • Madagascar has experienced the greatest extinction of primates in the recent past.

  • In Central and South America, hunting and forest fragmentation are the main problems for primates.

  • There are 21 critically endangered primates, with seven remaining on the IUCN's "The World's 25 Most Endangered Primates" list since the year 2000.

  • Miss Waldron's red colobus was recently declared extinct.
