 The idea behind DK1 is that we are inclined to believe in trees rather than trogs largely because prevailing conventions in the communities we were born into generally prohibit treating some things as the parts of a single object unless they are connected or in some other way unified. These conventions themselves likely trace back to an innate tendency to perceive only certain arrays of qualities as being borne by a single object and its being adaptive for creatures like us to so perceive the world. But the facts about which distributions of atoms do compose something, or about which arrays of qualities truly are borne by a single object, have no role to play in explaining why this is adaptive. Thus, it would seem that we divide up the world into objects the way that we do for reasons having nothing at all to do with how the world actually is divided up.
