Creature can feel it's evolving (4,6)

I believe the answer is:

leaf insect

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

'creature' is the definition.
(leaf insect is a kind of animal)

'can feel it's evolving' is the wordplay.
'can feel it's' anagrams to 'LEAF INSECT'.
But, I'm unsure how this is indicated.

Can you help me to learn more?

(Other definitions for leaf insect that I've seen before include "Small creature of the order Phasmida" , "Stick-like creature" , "Tropical bug" .)

I've seen this clue in The Guardian.
