Chimps, for example (4)
I believe the answer is:
apes
'chimps for example' is the definition.
(chimp is a kind of ape)
This is the entire clue.
(Other definitions for apes that I've seen before include "Copies the primates?" , "Peas (anag)" , "Imitates like primates" , "Parrots" , "Imitates in every aspect" .)
