Our distant relatives consume fruit drinks (5,4)
I believe the answer is:
great apes
'our distant relatives' is the definition.
I can't judge whether this definition defines the answer.
'consume fruit drinks' is the wordplay.
'consume' becomes 'eat' (to consume something is to eat it).
'fruit' becomes 'grapes' (grapes are fruit).
'drinks' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'eat' going into 'grapes' is 'GREAT APES'.
Can you help me to learn more?
(Other definitions for great apes that I've seen before include "Forest-dwellers" , "Primates" , "Our cousins" .)
