NEW YORK: New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to organisms when Earth’s first life was emerging from the primordial soup.
In the papers, University of North Carolina scientists Dr. Richard Wolfenden and Dr. Charles Carter, discuss two key stages of the process which brought life out of the primordial soup and ultimately resulted in the formation of plants and animals.
“We could be just a few decades from proving if there is life elsewhere,” says Heller, a post-doctoral fellow at McMaster’s Origins Institute who worked with Pudritz, a professor of physics and astronomy and director of the Origins Institute.
Unlike the RNA World theory, which claims that the molecule that is currently involved in the coding, regulation, and expression of genes, elevated itself from the primordial soup before going on to form short proteins known as peptides (and eventually single-celled organisms), the authors of the new study argue that RNA did not act on its own.
Many planets outside the solar system are even more massive than Jupiter, and they orbit their Sun-like stars at an Earth-like distance, but these faraway super-Jupiters are effectively giant gas balls that cannot support life because they lack solid surfaces.
