Early-Earth Cells Modeled to Show How First Life Forms Might Have Packaged RNA
October 14, 2012 A chemical model that mimics a possible step in the formation of cellular life on Earth four-billion years ago has been developed. Chemists created primitive cell-like structures that they infused ... > full story -
Fly Genomes Show Natural Selection and Return to Africa
October 12, 2012 New studies of the genomes of almost 200 strains of Drosophila flies show natural selection and a "return to Africa" of the tiny flies, which likely migrated with ancestral humans tens of thousands ... > full story -
Developmental Biologist Proposes New Theory of Early Animal Evolution That Challenges Basic Assumption of Evolution
October 11, 2012 A developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions -- that survival is based on a change's ... > full story -
Cambrian Fossil Pushes Back Evolution of Complex Brains
October 10, 2012 Complex brains evolved much earlier than previously thought, as evidenced by a 520-million-year-old fossilized arthropod with remarkably well-preserved brain structures. Representing the earliest ... > full story
