Physicist Graham Cairns-Smith has spent his whole logical profession pushing a straightforward, radical thought: life didn't start with fiddly natural atoms like DNA, however with basic gems.
It is presently a long time since Cairns-Smith originally set forward his thoughts regarding the starting point of life. A few researchers have mocked them; others have, circumspectly or wholeheartedly, grasped them. They have never become standard conventionality, however they have never entirely left either. Was there any fact to Cairns-Smith's challenging proposition? Did life truly originate from gems?
In June 2016 I visited Cairns-Smith and his significant other Dorothy at their home on the edges of Glasgow, UK. Presently 85, he has an uncommon condition identified with Parkinson's malady, which has influenced his portability. Be that as it may, his logical interest and his comical inclination stay undimmed.
