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

Well digging behaviors have been observed previously in areas with dry habitats, and researchers only know of three chimpanzee groups in the savannah that do so.

The primates may be burrowing for cleaner water

Over the span of 15 months, scientists cataloged 76 instances of chimps using insects on their wounds and the wounds of others.

Puppies Are Born Ready to Communicate With Humans

A new study finds very young dogs with little human contact can understand pointing gestures—and that the ability has a strong genetic basis

Previous research has shown that a gorilla's larger body size is linked to reproductive success and social rank. The chest-beating could be another way for the gorillas to convey their size to others and, in turn, avoid fights that could result in serious injury or death.

Gorillas Beat Their Chests to Communicate With Each Other

The larger male apes have lower frequencies in their pounds and may use chest-beating to signal their social status, strength, and size to others

After five weeks of development, a human brain organoid (left) is roughly twice the size of those from a chimpanzee (top right) and a gorilla (bottom right).
