A few years ago, anthropologists identified Energy Efficiency as the main reason for the evolution to upright walking. The study suggested that humans walking on two legs only used one-quarter of the energy than that of the chimpanzees who knuckle-walked on four legs, providing support for the hypothesis that human bipedalism evolved due to the fact that it used less energy than walking with four legs.

There are two types of innovation: Sustaining Innovation (better & sharper sword) and Disruptive Innovation (Slingshot). Goliath was in fact good at sustaining innovation: he sharpened his sword every day, and he worked out every day like Conan the barbarian.
