Gigantopithecus blacki went extinct at least 215,000 years ago after climate change caused its forest home to vanish.

Researchers studied chimpanzee and monkey anatomy to better understand how humans evolved to have flexible shoulders and elbows.

A small, proof-of-concept study in monkeys reveals the potential of a one-off gene therapy to treat people with alcohol use disorder who haven't responded to other treatments.

Adoptions in the animal kingdom may confer an evolutionary advantage, but other factors — such as empathy, the urge to care for babies and inexperience — could also contribute.

The rhesus macaques on Cayo Santiago that engaged in same-sex behavior were also found to have more babies, indicating an evolutionary advantage.

The mother repeatedly tried to catch the dead infant's gaze before throwing the corpse around her enclosure and eventually devouring it.

Experiments suggest that taurine, an unusual amino acid, can extend some animals' life spans, but it's unclear if it would work in humans.

Brain implants developed by Elon Musk's company Neuralink have been approved for human testing. The safety of the devices previously came under scrutiny following reports of "botched surgeries" in animal test subjects.

In a series of new experiments, Goffin's cockatoos were able to use a set of different tools to complete complex tasks. The brainy birds can decide which gadget works best and carry their varied equipment around with them.

Humans aren't the only species that has entered the Stone Age. Who else is in the club?
