Well, so far the response has been that abiogenesis (spontaneous
generation) is OK as long as the form that appears is undifferentiated.
Maggots or even bacteria cannot spontaneously appear; they are too
complex. So that leaves us with: what is undifferentiated life? Is an
autocatalytic set sufficiently generalized and undifferentiated? Is it
alive? Or is some measure of compartmentalization required to define a
discrete entity? That would probably constitute a differentiation, though.
Perhaps the entire primordial ocean (or maybe just the ocean bottom)
could be considered alive, with the entity's boundaries being supplied by
pre-existing structures. No DNA, no RNA, no genetic material at all,
just a lot of metabolism in a big chemical reactor. Is it alive?
Has abiogenesis occurred?
