Is it true that evolution always leads to more complex organisms?

No. Reference works and a textbook state that evolution has no intrinsic direction toward complexity and does not always lead to more complex organisms, with simple life remaining dominant. This directly contradicts the claim that evolution always leads to more complex organisms.
