Cynical outlook reported in most recent epoch? (8)
I believe the answer is:
holocene
'recent epoch?' is the definition.
(synonyms)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for holocene that I've seen before include "Current geological epoch; lone echo (anagram)" , "Relating to a modern epoch" , "Relating to the present epoch" .)
