RNA and DNA arose at the same time?

A new theory, via Phys.org:

“Even if you believe in a RNA-only world, you have to believe in something that existed with RNA to help it move forward,” said Ramanarayanan Krishnamurthy, associate professor of chemistry at TSRI and senior author of the new study. “Why not think of RNA and DNA rising together, rather than trying to convert RNA to DNA by means of some fantastic chemistry at a prebiotic stage?”
More.

But wouldn’t the confluence of DNA and RNA point to design? Anyway, why do w only hear of the problems with RNA world (“fantastic chemistry”) when some other theory that won’t work is being promoted?

    I absolutely love the scientific miracles. However, ever if this were true, there is much, much more to life emerging without “some help”. I “love” the world of nonsense called “science”. Lately, one can publish anything and get paid and even promoted…

    That’s fine. Why not? Don’t have any problem with that or the other way around.

    BTW, on the same token, maybe the authors of that pseudoscientific hogwash would like to buy a beautiful oceanfront condo on sale at a substantially discounted price right in the center of Kansas?
    It has an impressive 77th-floor 360° panoramic view of the Atlantic, Pacific and Indian oceans and direct access to secluded beaches on all three.
    Definitely a real estate jewel that may not last too long in the market.
    🙂

    The guys who wrote that bizarre nonsense seem to possess quite a creative imagination. They could easily write bestselling fiction novels.

    What’s the price? Could be interested… 🙂

    In a New Documentary, Origin, Paul Nelson and Ann Gauger Confront the Enigma of Chemical Evolution – October 3, 2016
    Excerpt: Origin is intended as a sequel to an earlier Illustra production, Unlocking the Mystery of Life. It’s a worthy follow-up that we can imagine enlightening a range of audiences.

    With all due respect to Lynn and appreciating the immense transition from chemicals to bacteria which includes the evolution the ribosome and ATP synthase to get to man requires the following transitions all arguably as difficult to explain as OOL.

    -the origin of the eukaryotic cell.
    -the origin of multicellular organisms
    -the origin of vertebrates
    -the origin of land animals
    -the origin of mammals
    -the origin of man

    gpuccio @4,

    FYI – a lot of Neo-Darwinism folks made strong offers with huge deposits to secure the deal advertised @2. Apparently the alleged ‘sellers’ ran away with the deposit funds and hid somewhere in an undisclosed location.
    The Neo-Darwinism buyers are still obliviously waiting… they haven’t realized what really happened. They won’t get their money back.
    Poor things.
