A number of controlled procedures were carried out which involved ruffling the feathers of chicks and mother hens with an air puff. When chicks were exposed to puffs of air, they showed signs of distress that were mirrored by their mothers.
A white tailed dear flips it's tail and the herd reacts. A wolf raises it's hackles and the rest of the pack reacts. Does that mean they both have empathy?
OTOH, wolves and dogs have shown other signs of empathy.
