If we, meaning humans now... find life somewhere else, most people would be disappointed if it turned out only to be bacteria. - Nick Lane

Does it make sense that life is cellular? Would you expect to find life being cellular elsewhere? I suspect that for organic life... it would be cellular.

They [bacteria] haven't used it [their more complex metabolism]... to give rise to more complex morphologies beyond the kind of stromatolite type structures, beyond s. That seems to be a limit. Some multicellularity, some degree of differentiation and complexity, but nothing... to compare with the flea.

[T]here's a limit to just how far vents can take you... but... once you've gotten as far as , then you've freed yourself from a fairly small energy flow, a fairly tight and focused energy flow.
