Animals and bees know to social distance when sick

Maybe humans aren't so smart after all. Researchers from Hamilton College, Virginia Tech and the University of Pittsburgh reviewed studies about how animal socialized during epidemics and found a wide variety of species take active steps to avoid spreading illness further. These include: unhealthy bats avoiding healthy ones, sick bees not returning to hives, apes and monkeys joining new groups or refraining from grooming other members who are ill.
