Darwin’s theory of evolution should be expanded to include consideration of a DNA stability “energy code”—so-called “molecular Darwinism”—to further account for the long-term survival of species’ characteristics on Earth, according to Rutgers scientists.


The iconic genetic code can be viewed as an “energy code” that evolved by following the laws of thermodynamics (flow of energy), causing its evolution to culminate in a nearly singular code for all living species, according to the Rutgers co-authored study in the journal Quarterly Reviews of Biophysics.

“These revelations matter because they provide entirely new ways of analyzing the human genome and the genome of any living species, the blueprints of life,” said senior author Kenneth J. Breslauer, Linus C. Pauling Distinguished University Professor in the Department of Chemistry and Chemical Biology
