Selecting life: Scientists find new way to search for origin of life

Over the last half century, researchers have found that mineral surfaces may have played critical roles organizing, or activating, molecules that would become essential ingredients to all life--such as amino acids (the building blocks of proteins) and nucleic acids (the essence of DNA). But which of the countless possible combinations of biomolecules and mineral surfaces were key to this evolution?
