I’m not buying it either.
If man was using tools 3 million years ago, he would have dominated the planet 2.994,000 years ago. No other species would have stood a chance against man with tools.
Seems about at least 2.5 million years too long ago.
Modern Homo Sapiens did not show up until 200,000 years ago.
This discovery took place just a couple hundred miles from where the Lucy fossils were discovered.
Lucy was more ape than human.
The tools were just flaked rocks.
