Research indicates bees live richer and more complex lives than previously thought.
For years, the concept of animal cognition and consciousness had many buzzing. Scientists were asking themselves, can animals feel emotions, sense pain, apply reason, display self-awareness? In other words, are animals — sentient?
Scientists now agree nearly all vertebrate species display, in varying degrees, some measure of sentience. Elephants display grief and mourning, grey parrots apply abstract concepts of shape and number, dolphins seek stimulation through play.
