Natural Selection - Competition for living
Since its inception, life has had as a main goal survival and the offspring. In the first forms of life, survival consisted of adaptation to the environment, the threats were formed by the different components of the environment. With the proliferation of new and different life forms, the threats increased to the same extent, since not only had dangerous components in the environment that could harm the existing organisms, but also other species competing for survival, in this way started a kind of race against time in which only the most suitable species would adapt to the changes of the environment, and survive the stiff competition that comes from living with other beings who have the same goals.

Since then, the dominant was the stronger, more resistant and faster, but this was bringing with it disadvantages such as requiring more resources than any other. For this reason, once again the capacity for survival overcame the force. In the face of such variations of resources, the smallest species was who could cope to this, their need for few resources and the possibility of protecting themselves from the weather gave them a huge advantage to survive.

While decreasing the threats of predators, many species began to migrate in search of the places with the climate and the adequate resources for their survival. By then then the species were considerably varied. The different migrations grouped many animals in remote areas, each one was facing different threats. Meanwhile, certain species had very little competition, so they could take care of other things. There were very few large animals, the strength stopped being predominant, and resources sneaked very quickly, so something more than speed was needed. Was needed technique, and with it intelligence. In this way the firsts humans species began to use tools, progressively with this they developed their intellectual capacity, and discovered the best weapon to survive, intelligence.
