How did homo erectus communicate?

Answer 1

In aII mammals, other than modern humans, the larynx is high in the throat, which allows the animal to breathe and drink at the same time. However, the resulting small pharyngeal cavity limits the range of sounds that can be produced, and most mammals depend on the shape of the oral cavity and lips to modify the sounds produced in the larynx. Modern humans are able to make a wide range of sounds because the larynx is situated low in the throat, thus creating a large sound-chamber, the pharynx, above the vocal cords. Jeffrey Laitman, Philip Lieberman and Edmund Crelin, demonstrated that the expanded pharynx is the key to producing fuIIy articulate speech. Human babies are born with the larynx high in the throat and can breathe and drink simultaneously, as they must during nursing. Homo erectus fossils show evidence that the larynx was high in the throat, so they would have been able to make a limited range of sounds. Even much less intelligent animals can be seen to communicate by sound. Homo erectus would have had the ability to communicate orally, perhaps using a limited range of speech, bu they could not have talked in the way Homo sapiens can.

Answer 2

Homo erectus likely communicated using a combination of gestures, body language, vocalizations, and possibly simple sounds or words. While they may not have had complex language like modern humans, they likely had the ability to convey basic information and emotions to one another.

Answer 3

They used their body and they also did sound with their mouth.
