Individual copies turned up to evaluate (8)
I believe the answer is:
separate
'individual' is the definition.
'copies turned up to evaluate' is the wordplay.
'copies' becomes 'apes' ('ape' can be a synonym of 'copy').
'turned up' shows that the letters should be reversed in order.
'to evaluate' becomes 'rate' (rating is a kind of evaluating).
'apes' in reverse letter order is 'sepa'.
'sepa'+'rate'='SEPARATE'
(Other definitions for separate that I've seen before include "Standing apart" , "Break up" , "solitary" , "Unconnected" , "Pull apart" .)
