So if you think of it from a protocell point of view, the selfish replicators which are the best at making copies of themselves are necessarily those… - Nick Lane

It's interesting... that life as a rule does not use UV radiation as an energy source, and the kind of chemistry that's being done using it doesn't resemble biochemistry as I know it... [T]he kind of environment that I'm talking about is deep sea s, and the question is, "Well, does it have to be deep sea? Could it... be same systems on land?" and they exist on land. They perfectly could. So it's perfectly feasible.

[I]t's interesting to me that the bacteriophages, the viruses that you find in bacteria, are not remotely similar to the ones that you find infecting archaea, which again are not remotely similar to eukaryotic viruses. ...They're different in their appearance. They're different in their mechanisms in which they force their... I mean the bacteriophages are these classic lunar module landing things... They are stunning things to look at. ...Some es look like bottle balls or postage stamps, strange shapes... They don't have any genes in common. They don't have mechanisms of entry into cells in common. They appear to be independently derived.

[Life is] a continuum. I think there are some phase transitions, probably, and the origin of... genetic information is probably one of them. ...[W]e are doing some modeling work to try and work out how evolvable... a geological system [can] be along the path to getting to cell-like things that... most people would understand as life. How far can you go down that line before you have genetic inheritance? ...[A] long way, but you get to a point where... it's no longer evolvable. ...[I]n our modeling, you can get to a point where you're capable of producing s capable of making copies of themselves with a degree of sophistication, but getting beyond that, to specializing to different niches and so on, I don't see the way, without genetic inheritance.
