> Made famous by zoologist Jakob von Uexkull in 1909, the term Umwelt refers to the perceptual world experienced by each animal, a highly specific kind of "sensory bubble." When we walk our dog and she stops to smell every other bush or car tire, she's taking in through her acutely sensitive nose smells that we take in faintly or not at all. That's because humans and dogs have two different sensory bubbles, or Umwelten.
