List four characteristics that are representative of most primates and lead paleoanthropology to conclude that primates share a common ancestry

- prehensile hands and feet

- five digits and opposable thumbs

- flexible and limber shoulders and hips

- big and complex brains

Explanation:

The primates are the most intelligent animals collectively, and they include the most intelligent animal on the planet, the human. All of them share some common characteristics that lead the paleoanthropology to conclude that they share a common ancestor. Most of them have prehensile hands and feet, which is a rare among other groups of animals. Almost all of them have five digits on their hands and feet, possessing opposible thumbs as well, enabling them to grab things. The shoulders and hips are also much different than the other animals, being much more flexible and limber. The most important characteristic maybe is their brain, as it is abnormally large and complex when compared with other animals of the same sizes. Their complex brains enable them to perform numerous things that other animals can't even imagine, and eventually that large brain helped in creating the most intelligent animal on the planet, the human.
