Human skin is capable of absorbing and storing vitamin D, allowing our species to survive in regions with almost no sunlight, as well as those where sunlight is abundant.

Innovations like the bow and arrow allowed humans to protect and feed themselves, and as a result they moved faster and more safely than other species.

Collective learning gave humans the tools they needed to travel far and to survive in different climates.
