In 1964, pre-historic remains were discovered at Jabal A\u1e63-\u1e62a\u1e25\u0101bah - or Mountain of the Companions - in the Nile Valley near what is now the border of northern Sudan and Egypt. That site contained evidence of the earliest known warfare believed to have taken place around 13,500 years ago. It\u2019s thought that climate change led to that conflict; as crop yields became smaller, more groups had to compete with each other for what food sources were available.

Spears and possibly arrows were the high-tech weapons of choice in the Nile Valley. Flash forward to today and it\u2019s AI-enabled drones that have been - literally - levelling the playing field for Ukraine in their battle against Russia.

But as technological advancement continues apace what lessons have we learned from recent conflicts and how might things change in the wars yet to begin?
