1 jan 2000000 ano antes da era comum - Use of Language

Descrição:

The complex brains of Homo sapiens allowed for cooperation and interaction with both their environment and each other, which was crucial to their evolution. Language, unique to Homo sapiens, likely developed either through imitating sounds or gesturing, later evolving into spoken communication. While language itself cannot be fossilized, evidence such as complex tools, symbolic art, and trade suggests that communication evolved gradually over the last 2 million years. Fossils show that earlier species like Homo ergaster and Neanderthals had some communication abilities, though limited compared to modern humans, while Homo sapiens had the full capacity for speech, evidenced by their brain structure and vocal tract identical to ours today.
