End of life, an evolution (6)
I believe the answer is:
finale
'end' is the definition.
(finale is the end of a show)
'life an evolution' is the wordplay.
'evolution' indicates anagramming the letters.
'life'+'an'='lifean'
'lifean' anagrammed gives 'FINALE'.
'of' acts as a link.
(Other definitions for finale that I've seen before include "Climax, end" , "Ending" , "In leaf (anag.)" , "Last song etc" , "Denouement" .)
