Life may be the universe's most efficient way to create disorder
In short: The second law of thermodynamics dictates that entropy—or disorder—must always increase in an isolated system. Yet, life is defined by its incredible complexity and order. This apparent paradox suggests that living things aren't breaking the laws of physics; they are actually perfecting them.
The confusion surrounding biological order often stems from a misunderstanding of 'isolated systems.' While entropy must increase in a closed environment where no mass or energy can enter or leave, life exists in an open system. Humans and plants provide a perfect analogy: we consume low-entropy food and ultraviolet light to maintain our internal order, but we simultaneously release high-entropy waste products and heat into our surroundings. In this exchange, the local decrease in entropy is always compensated by a much larger increase in the total entropy of the environment.
This principle explains why evolution does not violate thermodynamic laws. Earth is constantly bathed in energy from the sun, which transforms low-entropy matter into high-entropy radiation and heat. Because the universe is not closed, complex molecules can naturally combine to form larger structures without violating any physical constraints. In fact, organic molecules have been detected throughout the galaxy in interstellar gases, suggesting that their formation is a common occurrence rather than a thermodynamic impossibility.
A compelling theory by physicist Jeremy England suggests that life might be an inevitable byproduct of these laws. His 'dissipation-driven adaptation' hypothesis proposes that groups of molecules will naturally self-organize to become more efficient at absorbing and dissipating heat from their environment. Just as whirlpools form spontaneously in fluids to move energy, life may have emerged because it is exceptionally good at creating disorder. Under this view, reproduction and biological complexity are favored by nature because they allow systems to dissipate increasing amounts of energy more effectively.
