Enters the battlefield with an additional +1/+1 counter and Evolve
Let's pretend the board state is:
2/3 Gyre Sage (she has a single +1/+1 counter on her)
2/1 Metallic Mimic (declared as elf)
I cast Bramblewood Paragon and it enters the battlefield.
My question is:
Also note that this same logic applies to creatures that ETB with +1/+1 counters on them also.
