Original top hunter chap is ... me? (15)

I believe the answer is:

pithecanthropus

I'm a little stuck... Click here to teach me more about this clue!

'me?' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?

'original top hunter chap is' is the wordplay.
'original' is an anagram indicator.
'top'+'hunter'+'chap'+'is'='tophunterchapis'
'tophunterchapis' with letters rearranged gives 'PITHECANTHROPUS'.

Can you help me to learn more?

(Other definitions for pithecanthropus that I've seen before include "Ancestor" , "Old man" , "apelike man" .)
