Prehistoric humans were far smarter than previously assumed

An international study sheds new light on our cave-dwelling forefathers who lived more than 300,000 years ago.

The new study recently published in Science reveals that our forefathers were innovative thinkers who time and time again found new and better ways of doing things.

The study shows, among other things, that an especially advanced technique used to make stone tools was not just discovered once and then simply copied. Instead, the technique was discovered many times at different points in time across the globe -- which suggests that our forefathers were generally more resourceful than previously thought.
