Quiet passing of pioneer

I almost missed the news that Stanley Miller, of the famous Miller-Urey experiment, recently passed away.

The experiment has been criticised in recent years for making incorrect assumptions and encouraging an over-simplified view of how life originated. However, I think it’s important to place this work in the context of its time. It showed that the basic “building block” molecules of life could be synthesised via known, understood and relatively simple chemical processes. This means that given the right environment and ingredients, biochemistry goes from being unlikely to almost inevitable, with profound implications for the likelihood of life emerging both on the earth and elsewhere.
