s of some sort [lie between a hydrothermal vent system and a virus] in my mind. The trouble with viruses is that they do need a sophisticated environment to make copies of themselves. Same with selfish jumping genes, transposable elements and so on. They need to be in an environment where they can take advantage of something which is converting the environment into copies of themselves, and there's a rule... This is changing with the discovery of all these es, but as a rule you need some form of to convert the environment into copies of yourself.

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.

I think we share consciousness right across... not just even the animal world. I would see it going down even to the level of cells, some kind of flickering of consciousness. So I don't feel alone on earth, but I do think that there is something different about humans.

The double helix of DNA... is composed of two long chains [of 'letters'] that snake around each other... each strand providing an exact template for the other. ...[E]ach strand ...contains just four types of letter, with ...billions ...arranged down... the chain. ...3,000 million letters ...make up the human genome ...[T]he same — the same lines of code — can have different effects depending on the context.
