They say that many dog owners look like their pets. Dr. Lance Workman from Bath Spa University (just up the road from me) tested this out with a study to see if people could match 70 dog owners to their breed of dog. Apparently the hit rate was well above chance between 50-60% compared to 33% (I guess that will be choose one photograph from three then!).
We also have a tendency to attribute human qualities to non-human beings. This video made for the Athens Olympics shows what happens when anthropomorphism and human assimilation collide.
