Bushman close to you, moving below us? (8)
I believe the answer is:
subhuman
'below us?' is the definition.
(less than we humans)
'bushman close to you moving' is the wordplay.
'close to' indicates one should take the final letters (the close/ending of).
'moving' indicates anagramming the letters.
The final letter of 'you' is 'u'.
'bushman'+'u'='bushmanu'
'bushmanu' anagrammed gives 'SUBHUMAN'.
(Other definitions for subhuman that I've seen before include "Of a lower order than man" , "Neanderthal?" , "Debased, depraved" .)
