"Human beings are scary. We breathe a corrosive gas, drink one of the most potent solvents. Our preferred method of hunting was persistence hunting, where we chased animals until their body simply gave up and died. We can eat just about anything we find, which means that we don't need to stop for food when chasing our prey. If we can't find food, that's fine. Our body will simply begin to eat itself so that we don't have to stop chasing our prey. We walk upright, we sweat, we don't have much body hair, which allows us to radiate away our body heat. This means that excessive time or extreme environment wont stop our hunts. If the animal fights back against us, we can take massive damage to our extremities and lose half our blood and still live. Our entire existence is owed to persistence, endurance, and determination. When we put ourselves to a task, it gets done, period."
