Biology Quote by Jacques Monod
“Evolution in the biosphere is therefore a necessarily irreversible process defining a direction in time; a direction which is the same as that enjoined by the law of increasing entropy, that is to say, the second law of thermodynamics. This is far more than a mere comparison: the second law is founded upon considerations identical to those which establish the irreversibility of evolution. Indeed, it is legitimate to view the irreversibility of evolution as an expression of the second law in the biosphere.”

Evolution's irreversibility mirrors the second law of thermodynamics, linking biological change to entropy increase.
In simple terms: Evolution and entropy both move in one direction.
Recognize that change is inherently directional.
