I believe carrying weight is important but Curious. When you say that humans are the only species that can carry heavy weights over long distances, are you forgetting horses, elephants, llamas, alpacas, donkeys, mules . . .even some dogs?

Those species can only carry if a human straps weight onto them. Our ability to carry of our own volition is the critical difference.
