Examples of species penultimately displaced by humans (9)
I believe the answer is:
specimens
'examples' is the definition.
(specimen is a kind of example)
'species penultimately displaced by humans' is the wordplay.
I cannot quite understand how this works, but
'species' could be 'sp' (I've seen this in other clues) and 'sp' is present in the answer.
'humans' could be 'men' (man is a kind of human) and 'men' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for specimens that I've seen before include "Pisces men make prime examples" , "Samples of Pisces men" , "Representative samples" .)
