Chemical evolution describes a number of theories that assert that life originated through purely chemical transformations of nonliving matter. The idea is critiqued in The Mystery of Life’s Origin, by materials scientist Walter L. Bradley, geochemist Roger L. Olsen and chemist Charles B. Thaxton
- "chemical evolution," the idea that unguided natural processes produced the first living cells abiotically, from non-living materials This is contradictory to the modern scientific belief that life cannot spontaneously generate.
- Many evolutionary biologists now grudgingly acknowledge that no chemical evolutionary theory has offered an adequate explanation of the origin of life or the ultimate origin of the information necessary to produce it. - Stephen Meyer in Darwin's Doubt
