of life evolution. The following text, one of the firsts I wrote concerning this new paradigm, shows how Genismo can be understood through neodarwinian study of life evolution. Hierarchized Genismo Genismo is a meme that has happiness as a goal. Happiness is not only pleasure, but the addition of pleasure (and suffering) proportional to its duration on time. Suffering decreases the value of happiness while pleasure increases it [1]. By the theory of evolution and natural selection process, we know that living beings evolved *as* if they had the unconscious and instinctive goal of perpetuating their genes, that is: maximizing their gene-perpetuation. There is no transcendental reason for living beings to act this way. That happens because the genes that are present today are exactly those that were able to adapt their bearers to preserve them until the present moment. The genes that did not make their bearers perpetuate them, that is, were not able to make the organisms (phenotypes) that carried them pass them on to the next generations, perished. Those genes are not among us any longer. Therefore we are all living descendents of the first replicant (the primordial gene), which originated life about four billion years ago and was successful to survive through times [2]. For that reason, the base of evolutionary psychology, the science that studies the behavior and social structure of living beings is based on the gene-perpetuative paradigm. But how do genes make their bearers (us) act in a way to perpetuate them? Evolution and Consciousness Genes instigate their organisms to act in a gene-perpetuative way, as: Rigid and biologically codified mechanisms. That way, for instance, a plant does not need to think or feel it has to turn its leaves towards the sun in order to receive light: internal mechanisms turn the leaves in the direction of sunlight captivation. They execute this task automatically. Fructification or seed launching are also automatically done by the genetic regulation of the plant, with no help of any nervous system. Hyper primitive instincts In beings that own nervous system there are mechanisms codified by genes through mental algorithms (instincts) that instigate the organism to behave and act almost mechanically, without the need to think about its actions. Those algorithms are in general placed on the base of the brain, in the reptilian system. For example: breathing control, pupil dilatation in the dark, bristle of hair when cold, etc. The increase in the ability to survive and reproduce is a feature that helps genetic survival. Instincts that generate wishes or wills. Other instincts (=mental algorithms genetically codified to solve specific problems) do not produce directly an action in the organism, but impulses, wishes and wills, in a way that the organism itself, through other instincts or use of reason and logics, will decide the best way to satisfy them. In general, those mental algorithms that generate wishes and feelings are situated in the brain limbic system. Examples: anger, love, jealousy, etc. Reward mechanisms. Reward mechanisms are studied by a science area known as behaviorism. Those internal mechanisms make the organism
