HOW DID LIFE ORIGINATE?. SPONTANEOUS GENERATION. LIFE ARISING FROM NON-LIVING MATTER. LONG BELIEVED AS THE ACCEPTED EXPLANATION OF ORIGINATION OF LIFE. EXPERIMENTS EVENTUALLY SHOWED IT TO BE IMPOSSIBLE. Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. A mechanism for change in populations..
