Man placed different emphasis on keeping order (4,7)
I believe the answer is:
homo sapiens
'man' is the definition.
(Homo sapiens is an example)
'different emphasis on keeping order' is the wordplay.
'different' indicates anagramming the letters.
'keeping' indicates putting letters inside.
'order' becomes 'o' (abbreviation e.g. in British honours OM, OBE etc.).
'emphasis'+'on'='emphasison'
'emphasison' anagrammed gives 'homsapiens'.
'homsapiens' enclosing 'o' is 'HOMO SAPIENS'.
'placed' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for homo sapiens that I've seen before include "Relative of 1 across" , "The one existing species of Man" , "Modern humans" , "Human species" .)
