Notes praising evolution of pangolins (9)
I believe the answer is:
plainsong
'notes praising evolution of pangolins' is the definition.
I can't judge whether this defines the answer.
'of pangolins' is the wordplay.
'of' is an anagram indicator (the answer comes from or \'of\' the letters).
'pangolins' anagrammed gives 'PLAINSONG'.
Can you help me to learn more?
(Other definitions for plainsong that I've seen before include "Mediaeval church music" , "accompanied vocal music? No" , "Medieval style of church music" , "church melody" , "Lied, perhaps" .)
