The James M. DuPont Meteorite Collection - that "although the present evidence is not conclusive, there are good reasons for exploring possible origins of lifelike forms in the carbonaceous chondrites other than contamination after their arrival on earth." Biological Indicators Living things may be grossly regarded as unique assemblages of parts or molecules that possess efficient means of synthesizing, using highly select arrays of complex molecules, and of reproducing their specie. Plants can con- vert several per cents of the solar energy that they receive into molecular energy or food. Compounds which form a major portion of the constituent parts of organisms comprise an exceedingly small fraction of the compounds which theoretically can be made by abiotic reactions.
