The scientific name for Homo ergaster is Homo erectus ergaster.

Homo erectus and Homo ergaster are two distinct species within the Homo genus. Homo ergaster is considered to be an African species that eventually evolved into Homo erectus, which was more widespread and inhabited both Africa and parts of Asia. Homo ergaster is generally seen as a transitional species between Homo habilis and Homo erectus.

Homo ergaster is believed to have evolved around 1.9 million years ago in Africa during the Early Pleistocene epoch. It represents an early stage in the evolution of the Homo genus.

Homo ergaster

Homo ergaster likely had a basic form of communication using vocalizations, gestures, and possibly simple language. However, the specific languages spoken by Homo ergaster are unknown since they lived around 1.9 million years ago, and linguistic capabilities at that time are difficult to determine with certainty.
