Remember how evolution works: If a being stumbles on an imperfect solution and then never experiences a selection pressure strong enough to force a change, it won't get changed. Similarly, if there never arises a mutation that would change it, it won't get changed. Evolution is not focused on finding optimal solutions; it may eventually find one, but it is not guaranteed as part of the process.
