Anthropic principle, in its different forms, is cause of discussion in Cosmology. My question here is restricted to Biology. Are conditions of life's origin and evolution restricted in so form that they allow the emergence of intelligent life? The great difference would be that a biological anthropic principle is related to hazardous conditions (for example, extinctions by a meteorite), whereas the cosmological anthropic principle is related to fundamental constants. In fact, cosmological anthropic principle could take in account this biological , hazardous, aspect.
