Human behavior under risky or dangerous situations is considered somewhat irra-tional from the viewpoint of objective risks. Recent studies have shown that it is innate in nature and had been acquired in the process of evolution. This means that such behavior is adaptive and must have some kind of efficiency or advantage in natural selection. This paper constructs a simulation model of the human evolution process and tries to acquire risk related behavior of Agents. Agents, which simulate life histories of humans, have shown risk accepting behavior over a large parameter space that specifies the environmental condition in which the evolution takes place. The relation between behavior under risky situations and life histories of organisms is also discussed.
