tl;dr humans still aren’t special, consciousness seems to arise in quite a variety of nervous systems and working out what it is is a problem in neurology.
We declare the following: “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. Non- human animals, including all mammals and birds, and many other creatures, including octopuses, also possess these neurological substrates.”

The Francis Crick Memorial Conference, held in Cambridge last month, has come up with the Cambridge Declaration on Consciousness (PDF).
