Thank you, my friend PO1 Tony Holland for posting the unsurprising news that prehistoric human beings "invented" stone tools for agriculture, hunting and warfare as well.

I have always had an interest in prehistoric man. Did the Neanderthals disappear due to being killed, did they succumb to the climate, unable to compete for food, or bred out?

Nice read, thank you!
