Of the many questions that vex humanity, there is one above all others. It’s a question we’ve been asking ourselves since we realised we could ask ourselves questions. There are a lot of people who think they know the answer, even though there are almost more answers than there are people. Even so, we officially don’t know which of those many answers is the truth.
The question is; where did life come from?
If we gloss over the various theological discussions such a question evokes – if only because we haven’t got that kind of time – we still end up with an encyclopedia volume’s worth of theories, hypotheses, suppositions, and crackpot ideas. Primordial soup, panspermia and pseudo-panspermia, deep-hot-biosphere, the clay hypothesis, and several more. All of those ideas and those unlisted are encompassed under a single term: abiogenesis – which is the idea that life can spontaneously manifest out of non-living components. You might also hear the termbiopoiesis tossed about in this conversation, which is just a more specific reference to the three stages of the development of life. But these fancy scientific words are such a small part of the question, it’s unfortunate so many people get hung up on them.
