Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges.

The human brain had a vast memory storage. It made us curious and very creative. Those were the characteristics that gave us an advantage - curiosity, creativity and memory. And that brain did something very special. It invented an idea called 'the future.'
