Men stopped being hunter gatherers when the first supermarkets came about......canned beer and tv then sealed there fate as their usefulness was over.......most live a sedentary life and are easier to care for once gelded .....
I watched a Sir David Attenborough documentary about them.....the Black Kites don't have pocket to carry matches or indeed money to buy them ,so they mostly pick up burning sticks and fly them to different locations to start new fires and get smal rodents running.... :)
How the Blazes they worked that out is amazing...:)
