> we have created everything from a chihuahua to a great dane by artificial selection, but we cannot create a wolf from a dog thank you for this elegant, simple and actually really obvious insight. this is very helpful to me.   > aren't infinite, unrestricted affordances theoretically possible and thus any concievable life form (and infinitly many unconcievable ones aswell)? if they have to conform to the laws of physics, those affordances will always be restricted by the laws of physics. if not, who knows, but are we still talking about our universe or something else? > for example, they could have certain electromagnetic fields as their basic reference point and use their perception of the spacial dimensions only peripheral, like we use electromagnetic perception secondary to spacial ones. in those cases there would be no need for eyes or really for anything that resembles life as it is in reality or for anything that follows principles that could be derived from comparison with other life forms. but then that type of "vision" would conform to the physical properties of electromagnetic fields, just like our vision conforms to the properties of the geometry of 3d space
