Birds, dogs and cats are conscious.
Yes, in a way …
“The emergentist pursues every bit of common ground that he can discover between
humans and other animals — from the common chemical composition and structure of
DNA through the mechanisms of cell communication and regeneration to the development
of a central nervous system and brain to behavioural similarities to physiological responses.
Nerve cell similarities, for example, allow us to learn from
electrochemical responses in electric eels; brain plasticity is similar in frogs and
humans; we learn about our own social nature from mirror cells and from the
rudimentary theory of other minds in chimpanzees. Reconciling behaviours among
the great apes, and mutual caretaking among bonobos, help us understand our own
interdependencies more fully. All these continuities are for the good from a
scientific perspective.”
But …
“Yet humans are also discontinuous with our animal cousins. The significantly
larger frontal cortex and more complex anatomy of our brains has produced a
mental life and corresponding behaviours that are qualitatively different from our
closest animal relatives. We are, as Terrence Deacon so beautifully describes it,
‘the symbolic species’. One difference gives rise to another, in a beautiful
cascading effect of exponentially increasing complexity. Our disproportionately
large brains give rise to more varied language use and linguistic play; and more
complex language use in turn produces anatomical changes, such as larger
language areas, greater brain plasticity, and more complex interrelationships
among the brain regions. This is the famous thesis of the ‘coevolution’ of human
brains and human culture. Quantitative increases in complexity eventually lead to
qualitative differences, the emergence of new types of systems with correspondingly new types of causation.”
