Quirky English art: Humans to Martians (10)

I believe the answer is:

earthlings

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

'humans to martians' is the definition.
I can't tell whether this definition defines the answer.

'quirky english art' is the wordplay.
'quirky' indicates an anagram.
'english'+'art'='englishart'
'englishart' with letters rearranged gives 'EARTHLINGS'.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
