The thing is that that already assumes way too much about how people two million (!) years ago lived. Already there are lots of differences between modern hunter-gatherer societies, so why assume that one of these ways was the way we are "evolved" to be? Not too long ago archeologists found remains of the earliest people found in my area. The theory was that they mostly killed small prey (think rabbits) and ate fruit, vegetables and insects, so there would be no need to carry back large prey. Another comment links to an account of hunter gatherers running around, tiring their prey to death, discounting the idea that people in hunter-gatherer societies do not run long distances.
