Cutting edge training developed the human brain 80 000 years ago

Advanced crafting of stone spearheads contributed to the development of new ways of human thinking and behaving. This is what new findings by archaeologists at Lund University have shown. The technology took a long time to acquire, required step by step planning and increased social interaction across the generations. This led to the human brain developing new abilities.
