Question

In your Biological Anthropology class, you are given photographs of a fossil. It has a postorbital bar and convergent eyes as well as a relatively large brain. What might you conclude about this fossil

Answer 1

The fossil belongs to primates.

Primates are an order that belongs to the class Mammalia, which includes animals like monkeys, lemurs, apes, humans, etc.

Primates are a diverse group of animals that cannot be distinguished by just one trait instead they can be distinguished based on an array of characters.

Some distinguishing characteristics primates possess are:

• A bony ring structure to protect the side of the eyes from the muscles involved in chewing is known as the postorbital bar.
• All primates have convergent eyes which means that both the eyes have overlapping visual fields and only allow vision in front.
• Most primates have trichromatic vision.
• Primates possess relatively larger brains compared to other mammals. They also have a more complex brain.
