From Andrew Hawkins, Peaslake, Surrey, UK
Your feature explained a concept that was new to me, a form of evolution in chemistry as a potential origin of life on Earth. The idea dates back to at least 1944 and Erwin Schrödinger’s book What is Life?. I want to thank your contributor Elise Cutts for her brilliant prose, allowing one of your many lay readers with no scientific background to grasp the idea and its significance in the mystery of how life on Earth got started(26 April, p 34).
