    HAROLD CLAYI ON UREY April 29, January 5, BY JAMES R. ARNOLD, JACOB BIGELEISEN, AND CLYDE A. HUTCHISON JR. HAROLD UREY WAS A SCIENTIST whose interests, accomplish- ments, and influence spanned the disciplines of chem- istry, astronomy, astrophysics, geology, geophysics, and biol- ogy. Although he was meticulous in his attention to cletail, his sights were always on broad questions at the forefront of knowlecige. His unusual powers of concentration and capacity for hard work accounted for much of his success in exploring en cl opening up major new fields of research, including his discovery of deuterium and work

    Controversies on the ursprung of life

     

    Summary. Different viewpoints, many with deep philosophical and historical roots, have shaped the scientific study of the origin of life. Some of these argue that primeval life was based on simple anaerobic microorganisms able to use a wide inventory of abiotic organic materials (i.e. a heterotrophic origin), whereas others invoke a more sophisticated organization, one that thrived on simple inorganic molecules (i.e. an autotrophic origin). While many scientists assume that life started as a self-replicative molecule, the first gene, a primitive self-catalytic metabolic network has also been proposed as a starting point. Even the emergence of the cell itself is a contentious issue: did boundaries
