quote:
Natural selection: The differential contribution of offspring to the next generation by individuals of different genetic types but belonging to the same population.
I'd add that the differential reproductive success would have to be due to some
heritible trait or property.
If a meteor lands directly on you (i'm not talking about the subsequent change in the environment after a meteor hits. That could be a valid selective pressure), you have differential reproduction but not due to any fault or virtue of your own; there does not exist a phenotype that could survive such an event.
