It’s really cool that UK puts scientists to its own money. Most countries will go with politicians, buildings and warlords. I have to say that it saddens me to see Darwin go. Considering that the evolution theory is still considered controversial in many places(even in advanced countries like the US) I think it was a very bold move to have him on the note.
There's a lot of wacky people with wacky ideas in the UK... but I think almost literally nobody disbelieves evolution here. It's just not a thing on anyone's radar and the small component we have of evangelical christianity is strangely quite an urban middle-class thing. I don't think it was bold at all.
