  • Downer article on "chemical gardening"

    From erik simpson@21:1/5 to All on Thu Nov 18 08:39:51 2021
    A sobering look at laboratory "chemical gardens" where remarkably life-like structures are produced. They are compared to identifications of multi-Gya
    microbial fossils. Say it ain't so.

    I just noticed it, but it's not hot off the presses. I'll look for reactions to it.

    The possibility of inorganic deposits being mistaken for archaean fossils is being taken inot account:

    Definitely relevant to the future examination of rocks recovered from Mars, as well as putative "homemade" fossils.
