Just heard about this....anyone have more familiarity/info? Does this provide any insight into abiogenesis?

You have heard of DNA and RNA, but what about TNA? It resembles its more famous cousins in almost every respect, except that it is based on a sugar called threose instead of the deoxyribose found in DNA and the ribose in RNA. Researchers have speculated that because threose is a simpler sugar than ribose, TNA could be a long-lost precursor to RNA.
… has shown that TNA can be assembled by natural enzymes.

Threose nucleic acid (TNA), glycol nucleic acid (GNA), and PNA, lack experimental evidence for their respective abiogenesis.
