Hominins are classified as a tribe (Hominini) of primates, a type of mammal. Hominins are part of the family, or larger group of primates, called hominids. Hominids include orangutans, gorillas, chimpanzees, and human beings. All hominins are hominids, but very few hominids are hominins.

According to paleontologist Lee Berger, hominins are primates that share characteristics such as "bipedalism, reduced canine size, and increasing brain size."

The only hominins alive today are human beings. There are many, many extinct hominins, a fraction of which are represented here. Fossilized remains of extinct hominin species have been found in parts of Africa, Europe, and Asia, many dating back millions of years. Launch the GeoStory above to find out more.
