The big idea: will we ever make life in the lab?

Synthetic biology seems to promise the creation of artificial life forms.

No scientist has ever created a living thing from scratch.

But the mere fact that life appeared on a planet that was once little more than rock, water and simple molecular gases in the atmosphere shows that making life from scratch must be possible.

We have no idea how one might organise all these parts to organise into something alive.

Scientists don’t even agree on what “life” means in the first place.

Last year , Google described how computer programs that replicate themselves emerged spontaneously from non-replicating ones when they had the ability to join and split.

For me, “created life” has to be able to, at least metaphorically, crawl out of the test tube.
