Am Clark, working for a French naturalist (7)
I believe the answer is:
lamarck
'french naturalist' is the definition.
(I know that Jean-Baptiste de Lamarck is a natural scientist\nI know that (HasCountryOfCitizenship c8b2e941 France)\nI know that (IsA HasCountryOfCitizenship LocationAttributeProvider)\nTherefore, Jean-Baptiste de Lamarck is French\nTherefore, Jean-Baptiste de Lamarck is a French natural scientist)
'am clark working' is the wordplay.
'working' indicates an anagram.
'am'+'clark'='amclark'
'amclark' is an anagram of 'LAMARCK'.
'for a' acts as a link.
Can you help me to learn more?
(Other definitions for lamarck that I've seen before include "J.B.de -, eighteenth century French naturalist" , "scientist" , "proponent of evolution" , "Evolution theorist" .)
