Leaves that are green

Tom Sutcliffe, during Start the Week (BBC R4 1/12/14), was discussing evolution and other matters with Jules Pretty, Andreas Wagner,  Ruth Padel  and Chris Stringer. In a casual comment he suggested  "solar panels don't grow on trees" only to catch  himself on, as they say in Belfast, as the panel indulged in collective harrumphing!

 Oh yes they do!
