Charles Darwin

The theory of evolution more than a century ago, Charles Darwin and Alfred Russel Wallace proposed one of the more powerful theories to explain the characteristics of living things: the theory of evolution of species through natural selection Darwin 1859. This theory was derived in much of the knowledge possessed humans from millennia ago, the domestication of plants and animals. Thousands of years ago, humans began to domesticate plants and animals. Domestication probably started accidentally. The first humans began to cultivate certain species of plants and species, probably discarded plants less met their needs, consuming those that had better features. The more sweet and juicy fruits were preferred to the most bitter, dry, so that the latter were probably not consumed, while the first seeds were planted. The fruit produced by the seeds acquired the characteristics of the parent plants. Similarly less aggressive wolves, who are most helped humans in their activities hunting, watch, fun, were fed and bred with wolves similar characteristics, while the wolves more aggressive and less cooperative were repelled, which did not interbreed with the first.

So the children of such cooperative wolves behaved similarly to their parents. Thus, little by little, humans began to interfere with the survival and reproduction of these species, improving survival and reproduction of those plants and animals that most benefited. At some point, humans became aware of this mechanism and started selecting a much more planned to plants and animals used for breeding. In this way human beings gave rise to a variety of domestic animal breeds, as well as houseplants. Wolves domesticated dogs gave rise to the present. This occurred in a similar way with horses, llamas, cats, pigs, camels, cows, sheep, bees, and many other animal species. The same happened with plant species such as maize, rice, wheat, soybeans, oats, barley, bananas or banana, apple, cassava, tomatoes, and many others.

Darwin and Wallace realized that just as humans can alter the species of plant and animal specimens, selecting the most benefit you, nature itself can select plants and animals that use their resources better. Just as the wolf man can choose the most friendly and hard to give rise to the domestic dog, wolf, nature chooses the most able to survive and reproduce in the wild environment. Thus, the environment can alter the shape and behavior of living things. An overwhelming amount of evidence supporting the theory of evolution. Geological studies have confirmed the extremely advanced age of our planet, so that the enormous period of evolution of living things that this allows, explains the great complexity and variety of species. Large numbers of fossils have helped to find the common ancestors of species that our eyes are very different. Computer simulations have allowed to recreate the evolution from small random variations over long periods of time. However, the theory of evolution seems to predict a selfish behavior of living beings, not an altruistic behavior. Importantly, in biology, an altruist is one that benefits others in doing so damaging the same. If there are people selfish and altruistic beings in a species, selfish beings receive more benefits than altruistic beings, since the former receive assistance from the altruistic, but without harming themselves by not offering them any help. Therefore, long-term altruistic beings should be extinguished. This contradicts the behavior of some species, in particular, the behavior of the vast majority of human beings..
