Human evolution implies the existence of an algorithm (taxonomy) to achieve a purpose. The first step appears to be putting the purpose into action.
The second step is then finding a way to optimize the energy; thus the energy conservation principle is applied.
When this taxonomy is respected and successful, individuals are evolving. This implies that they add value to the environment, obtain the counterpart and learn from the environment at the same time.
Evolution implies being aware of reality and making conscious actions in order to adapt to the environment.

NOTE: The Unicist Research Institute is the major research organization in the world in its specialty based on more than 3,500 researches in complexity science, until September 2010, applied to individual, institutional and social evolution. The applicative researches are based on the discovery of the Ontogenetic Intelligence of Nature and the consequent Unicist Ontology of Evolution.
