Scientists propose sweeping new law of nature, expanding on evolution

Nine scientists and philosophers proposed a new law of nature that includes the biological evolution described by Darwin as a vibrant example of a much broader phenomenon

When British naturalist Charles Darwin sketched out his theory of evolution in the 1859 book On the Origin of Species - proposing that biological species change over time through the acquisition of traits that favour survival and reproduction - it provoked a revolution in scientific thought.

Now 164 years later, nine scientists and philosophers on Monday proposed a new law of nature that includes the biological evolution described by Darwin as a vibrant example of a much broader phenomenon, one that appears at the level of atoms, minerals, planetary atmospheres, planets, stars and more.

It holds that complex natural systems evolve to states of greater patterning, diversity and complexity.

"We see evolution as a universal process that applies to numerous systems, both living and nonliving, that increase in diversity and patterning through time," said Carnegie Institution for Science mineralogist and astrobiologist Robert Hazen, a co-author of the scientific paper describing the law in the journal Proceedings of the National Academy of Sciences.

Titled the “law of increasing functional information,” it holds that evolving systems, biological and non-biological, always form from numerous interacting building blocks like atoms or cells, and that processes exist - such as cellular mutation - that generate many different configurations. Evolution occurs, it holds, when these various configurations are subject to selection for useful functions.

"We have well-documented laws that describe such everyday phenomena as forces, motions, gravity, electricity and magnetism and energy," Hazen said. "But these laws do not, individually or collectively, describe or explain why the universe keeps getting more diverse and complex at scales of atoms, molecules, minerals and more."
