One of the most distinguishing characteristics of hominids is the ability to walk upright. They also have large brains, which have expanded with time. Hominids have smaller jaws and teeth, but their brains are larger and are well-suited for complex social behaviors. Hominids are also known for their ability to climb trees. And unlike most mammals, they are able to walk upright while holding things in their hands.

Types of Hominids

Earlier hominins possessed jaws that faced forward. This characteristic is called prognathism. Early hominins had smaller brains, which were only one-third of the size of modern human brains. In addition, their skulls were wider below the brain case, while modern human skulls are widest in the temple region. Early hominins also had pronounced canines, but these teeth were later lost. In addition, early hominins had large jaws, which had powerful jaw muscles.

Hominins were related to both modern humans and chimpanzees. The former group split from humans about 5 million years ago. Throughout history, hominins evolved into many different species, including humans, orangutans, and chimpanzees. In the present day, there are only a few species of hominins, but they are a separate subgroup.

Hominin fossils are often depicted in textbooks. Neanderthals are portrayed as culturally primitive, but they probably had similar intelligence to humans. They were also known to possess high technology, and their skeletal features are similar to those of modern humans. Australopithecines, on the other hand, were characterized as unintelligent. Homo erectus, meanwhile, walked upright and had a brain size comparable to modern humans.
