Draw in new capital (6)
I believe the answer is:
darwin
'capital' is the definition.
(Darwin is an example)
'draw in new' is the wordplay.
'new' is an anagram indicator.
'draw'+'in'='drawin'
'drawin' is an anagram of 'DARWIN'.
(Other definitions for darwin that I've seen before include "I'd warn this natural scientist" , "Originator of the theory of evolution" , "Evolution pioneer" , "He proposed the theory of evolution" , "Charles . . . . . ., author of 'The Origin of Species'" .)
