What do monkeys do with their dead babies?

Sometimes when ape or monkey infants die, their mothers continue to groom and hold the tiny corpses for days, weeks or months, even as the babies' bodies decay or become mummified. That distressing behavior is more widespread than previously thought, a new study finds.

Do chimpanzees mate with siblings?

High-ranking males have been known to coerce their sisters into mating with them. For the chimpanzees at Gombe, only one of four known offspring of such close matings made it to adulthood. "Breeding with a brother is a pretty costly mistake," Walker said.

Why do monkeys hold each other?

Why do some monkeys reject their babies?

Infant abandonment by monkey mothers in suboptimal conditions for reproduction and parental investment suggests that neglect, at least in its most extreme forms, may be an adaptive behavior. In contrast, several lines of evidence indicate that infant physical abuse is a maladaptive form of aggression or parenting.

Do monkeys try to mate with humans?

There have been no scientifically verified specimens of a human–chimpanzee hybrid, but there have been substantiated reports of unsuccessful attempts at human/chimpanzee hybridization in the Soviet Union in the 1920s, and various unsubstantiated reports on similar attempts during the second half of the 20th century.
