Full Answer

Monkeys are primates and, through examination of their fossil remains, it has been scientifically concluded that humans are the product of primate evolution. Homo sapiens descended from chimpanzees millions of years ago.

Primates and humans are both mammals, have the ability to walk upright and have opposable thumbs. When eating, primates use their teeth similarly to the way humans do. Both groups use their back teeth to crush food before swallowing. Both are omnivorous, meaning they eat all kinds of food, including meats, grains, fruits and vegetables.

In addition, both primates and humans have arms that are oriented on the side of the chest, not the front. Ribcages are similar between the two species; they are wide from side-to-side, but shallow front-to-back. On the inside, all organs are arranged the same in humans and apes.

It is thought that Homo sapiens branched off from chimpanzees somewhere around 5 to 8 million years ago, a relatively short span in evolutionary terms. That is why so many similarities still exist.
