yeah they must have invented hunting sticks and mud huts because otherwise why are the walking upright ?
the point of walking upright is it frees up your hands to do something with them like throw sticks. chimps have hands like us but they can't use those hands because they're always hanging from branches. you need a hand AND upright posture before you can do something interesting.
what Niggers can NOT do is plan for winter, because they can never think that far ahead in time. their time preference is i get hungry - i go kill something and eat it ( maybe i eat my neighbor ). i get horni - i rape a woman. we ran out of women to rape ? we go invade neighboring village steal theirs.
