Did anyone else notice how carefully chosen his words were? Instead of saying 'adult female' he said 'female adult'.
'Female adult' is correct, but that word order places emphasis on the adult bit, not the female. 'Female' is used as an adjective here.......which is more subjective.
'Adult female' places the emphasis very much on the 'female', a noun.
Also, if he'd given the dictionary definition, I'm sure some people would have lost their minds over it.
