I have a mental image of a humanoid species with hands possessing three fingers and two thumbs, on opposite sides of the hand:
*note: it could be animalistic or reptilian, it doesn't need to be exactly humanoid.
-What creatures would this species evolve from?
-Why would that species have evolved this design?
