Based on what is now known about these single - celled organisms, is it reasonable to assume that they are so simple that they could have appeared spontaneously?
Kas ehk oleks selle põhjal, mida neist ainuraksetest organismidest praegu teatakse, mõistlik arvata, et need organismid on sedavõrd primitiivsed, et võisid tõepoolest iseeneslikult tekkida?
