Evolutionary Brain Power Required for Humans To Invent New Tools

GreenTracker| Researchers using computer modeling and tiny sensors embedded in gloves have explained why it took early humans almost two million years to move from razor-sharp stones to a hand-held stone axe.

Neuroscientist Dr Aldo Faisal, the lead author of the study from the Departments of Bioengineering and Computing at Imperial College London, explains that the advance represented a massive technological leap in the brain development of our early human ancestors.

Interestingly, our study reinforces the idea that tool making and language evolved together as both required more complex thought, making the end of the Lower Palaeolithic a pivotal time in our history. After this period, early humans left Africa and began to colonise other parts of the world.” via Science Daily
