In 2012, a group some of the most brilliant thinkers of our time, including Stephen Hawking, came together to declare that animals do in fact have emotions:
"The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors. Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological substrates that generate consciousness. Nonhuman animals, including all mammals and birds, and many other creatures, including octopuses, also possess these neurological substrates."
The passage might seem dry and technical, but it has animal lovers cheering.
