Monkey babies are very active, spending much of their waking hours playing.

The average chimpanzee has over 5 times the upper-body strength of a human male.

Young chimpanzees have outperformed human college students in tasks requiring remembering numbers.

Monkeys use vocalizations, facial expressions, and body movements to get their messages across.

Just like humans, chimpanzees make tools and use them to acquire foods and for social displays.

Also like humans, they are status conscious, manipulative and capable of deception.

They show laughter-like vocalizations in response to physical contact, such as wrestling, play chasing, or tickling.

Humans and chimpanzees share similar ticklish areas of the body, such as the armpits and belly.

Ground breaking research found 99% identical DNA between human beings and chimpanzees

A study in the 1960’s concluded that chimps are capable of learning sign language.

Grinning, or pulling the lip up to show the teeth is a sign of aggression or anger because biting is one way monkeys fight and defend themselves.

Monkeys also express affection and make peace with others by grooming each other.

Monkeys can live up to the age of 40 in the wild.

An increasing number of governments are forbidding the use of chimpanzees and other great apes in research or toxicology testing. As of 2006, Austria, New Zealand, the Netherlands, Sweden, and the UK had introduced such bans.
