An Evolutionary argument for human-level [[AGI] AI] is an argument that uses the fact that evolution produced human level intelligence to argue for the feasibility of human-level AI1. Evolution is an extremely slow, random and erratic process, sometimes compared to a drunkard’s walk 2 or a "… a morally blind, fickle, and tightly shackled tinkerer"3. It has, however, produced human intelligence in this manner, then intelligent humans with a plan should produce it much faster. Bostrom and Shulman4 formalize the many steps of the argument for non-hard human level AI as follows:
"*1’. Evolution produced human intelligence.
_________
There are variations of this argument, some argue for the easily feasibility of human level AI through the use of evolutionary algorithm .These arguments use estimates on the total amount of computational power needed to simulate the entire evolution of human level intelligence and argue such level of computational power is well within range. Bostrom and Shulman5 argue that, in fact, it would take more than a century of Moore’s Law progress in order to match the entire evolution of intelligence computational powers. They also make a careful analysis of Evolutionary argument for human-level AI considering observation selection effect.
