Primate wee in coal scuttle (7)
I believe the answer is:
hominid
'primate' is the definition.
(hominid is a kind of primate)
'wee in coal scuttle' is the wordplay.
'wee' becomes 'mini' (I've seen this in another clue).
'in' indicates putting letters inside.
'coal scuttle' becomes 'hod' (I've seen this before).
'mini' put within 'hod' is 'HOMINID'.
(Other definitions for hominid that I've seen before include "Any extinct ancestor of man" , "Man, including fossil types" , "Man's cousin" , "Member of zoological family of humans and ancestors" , "Man or manlike creature" .)
