Primates

As one Nile crocodile rests, another perks up near a river in Tanzania.

Nile Crocodiles Recognize and React to the Sound of Crying Babies

The reptiles may be aware that primate infants are in trouble—and an easy meal

The Tusk Gorilla Trail features 15 life-size sculptures decorated by prominent artists and public figures.

Why a Trail of Life-Size Gorilla Sculptures Popped Up in London

The statues seek to raise awareness of wildlife conservation efforts in Africa

Scientists observed two separate groups of orangutans making biphonations, or two sounds at once.

Orangutans Can Beatbox, Just Like Humans

The primates can simultaneously make sounds with their mouth and throat, a finding that may shed light on the evolution of human speech

The new research sequenced the genomes of more than 230 primate species, 58 percent of which are threatened with extinction.

What the Largest-Ever Study of Primate DNA Reveals About Ourselves

The findings cover not only conservation and primate evolution, but also human health and diseases

Masturbation may help reduce STIs and increase fertilization in male primates.

Male Primate Masturbation May Have Evolved to Prevent STIs

The behavior originated some 40 million years ago to improve breeding success and protect against pathogens, according to a new study

Scientists Create 'Synthetic Embryos' From Monkey Cells

By studying lab-grown stem cells, scientists hope to shed light on miscarriages and birth defects

The baby western lowland gorilla is the zoo's first since 2018

In a recent study, researchers examined 40 videos of great apes spinning on ropes and calculated their average rotational velocity.

Great Apes Love to Spin Around—Here's Why

A recent study suggests that apes, like humans, seek out altered mental states

A long-tailed macaque uses a stone to get at food. The striking of one stone on another accidentally creates stone flakes the monkeys don't use.

Stone Flakes Made by Monkeys Raise Questions About Early Human Tools

The flakes accidentally produced by long-tailed macaques resemble those thought to have been made by early humans

Primate-Like Critters Survived in the Arctic When It Was a Lush, Warm Swamp

Even as darkness gripped the forests for months, two small species made it home

A mouse lemur grasps onto a tree branch in Madagascar. Scientists looked to characteristics in such modern primates to form a hypothesis about how primates behaved after an asteroid wiped out non-avian dinosaurs.

Soon After Dinosaur Decimation, Our Primate Ancestors Began Pouncing on Prey

Nails helped them climb trees quietly, and forward-facing eyes helped with depth perception to aid in precise leaping

This aye-aye is not picking its nose, at least at the moment. 

This Primate’s Long Middle Finger Has a Startling (And Rather Gross) Use

The aye-aye, long seen as spooky, spurred scientists to probe into primate nose-picking

The chimpanzees only share their identity while traveling, which may help avoid confrontations.

Chimpanzees Play Their Own Signature Drumbeats to Stay in Touch

New research suggests the animals broadcast their identity and location to find each other while traveling

By studying the throats of 43 primate species, researchers found they all had vocal membranes that destabilized their voices. Humans, on the other hand, do not.

The Evolutionary Trait That May Have Led to Human Speech

“Vocal membranes” in primates make their speech grating and unpredictable, study suggests. Humans have no such thing

Captive gorillas make a novel sound that's a cross between a sneeze and a cough when zookeepers are nearby with food.

Gorillas Make a New ‘Snough’ Noise to Grab Their Keepers’ Attention

Researchers have never observed gorillas making the unusual sound in the wild, suggesting that captive gorillas can learn to make new noises

In the midst of fire- and drought-ravaged savanna in southeastern Madagascar, a curiously lush green forest is home to myriad unexpected life-forms, including a species of mouse lemur.

Famed American biologist Patricia Wright explores an astonishing breadth of biodiversity in the wilderness of Madagascar

A gorilla sleeps in a forest in Rwanda.

Why Humans Sleep Less Than Their Primate Relatives

Ancient humans may have evolved to slumber efficiently—and in a crowd

Scientists identified an odor receptor that detects a synthetic musk used in fragrances, and another that detects underarm odor.

Humans' Sense of Smell May Be Worse Than Our Primate Ancestors'

The recent study also identified two new scent receptors for musk and body odor

Red-handed tamarins have greater vocal flexibility, using calls ranging from territorial long calls to chirps to trills to communicate, whereas pied tamarins use long whistle-like calls.

Red-Handed Tamarins Can Mimic Other Species' Accents

The South American primates change their calls to communicate with other tamarin species living in shared territories

As they have gotten more comfortable with screen-time, the chimps have shown human-like behaviors like bringing over food like nuts to snack on as they watch.

Czech Chimpanzees Use Video Calls to Fight Lockdown Blues

Zookeepers at Safari Park Dvůr Králové and a zoo in Brno set up daily video calls for their chimpanzees
