De la sabana a Marte

The first specimens of our species competed with lions to hunt zebras and gazelles in the African Serengeti. Two thousand centuries later, lions continue to hunt the same zebras and gazelles with the same methods and in the same places as they did then. We, on the other hand, have colonized every corner of the planet and have achieved immeasurable levels of prosperity and well-being. How have we achieved it? Well, thanks to that kilo and a half of gelatinous mass that we have between ear and ear that we call "brain" and that provides us with a natural intelligence with which we generate three types of ideas: scientific ones, which allow us to understand the functioning of the universe; technological ones, which make things available to mortals that ancient thinkers believed only almighty gods could do - from flying like Mercury to hearing conversations from a distance like Odin - and, finally, social ideas, with which we organize and we coordinate economies of billions of people, in which each one carries out a small task but where together we do everything. As individuals we are pathetically useless, which is why the humans who survived the attacks of Pleistocene beasts worked as a team. We are the descendants of those who knew how to form small societies in which everyone helped each other. From there comes our strength as a species, the strength that has made it possible for humans to write an incomparable history throughout the centuries.
