The only reason that I can see this affecting my life, personally, is it could be construed that if a person doesn't believe in evolution, then they don't apply logic, when necessary (in other matters).
By rejecting, or not sufficiently understanding, evolution, people are basically providing a rationalization for their dangerously idiotic anthropocentric conception of the universe. This allows them to treat any and all species other than human as simply existing solely for them to exploit. Consequently, we think nothing of causing mass extinctions, "processing" hundreds of billions of animals every year through concentration camps so that they (humans) can fulfill their lifelong dreams of being lazy and obese, etc.
