We are apes
This is information that has been around for a while. However, when is described in the way it is here, it really should make us think about our nature. We, humans, are the product of evolution, despite whoever speaks against it. The people who despise evolution describe it as a “mere theory”. As a matter of fact, a theory is: a well-substantiated explanation of some aspect of the natural world; an organized system of accepted knowledge that applies in a variety of circumstances to explain a specific set of phenomena. The atomic theory explains the world, however no one has ever seen an atom. It is not necessary to see the atom. These are the situations in which theory and fact become one single entity. Finally, the only way of improving ourselves is understanding who we really are. We carry in our DNA the selfishness needed for survival. After all, the guys who invented the original sin were not lying to us.
