Origin of Life: enzymes (Introduction)

This paper breathlessly tells us that the research may lead to understanding how enzymes evolved. The whole process of this research is by intelligent design in the lab and the result doesn't look anything like natural enzymes!-"Like all proteins, the new RNA ligase enzyme is a chain of amino acids folded into a 3D structure, but the resemblance stops there. Natural enzymes, like all proteins, are made from alpha helices and beta strands. Seelig's artificial enzyme lacks those structures. Instead, it forms around two metal ions and is not rigid. "Compared to enzymes we know from nature, the artificial enzyme has a rather unusual structure and dynamics," Seelig says."- Read more at: http://phys.org/news/2013-01-unveil-artificial-enzyme-evolution-tube.html#jCp-To remind the unscientific mind: without enzymes organic reactions just don't happen in the immediate present. They take forever. Life requires immediate results. Another problem for those who propose that enzymes appeared by chance, in shifting from an inorganic Earth to a planet with organic life!
