Earliest humans engaged in trading 3.2 lakh years ago: Study
The earliest Homo sapiens likely traded using colour pigments and developed more sophisticated tools than their ancestral Early Stone Age species, as per scientists from the Human Origins Program. The artefacts found in Kenya date to 3.2 lakh years ago, same as the oldest-known Homo sapiens fossils, pushing the human evolutionary timeline back by around one lakh years, said researchers.
