How did minds first evolve out of matter? Could consciousness have evolved more than once? How do we tell which living things have minds? Is there something it’s like to be a crab and live a crab's life? This week we’re thinking about “Minds and Matter.”
What Is It
Everything that seems to have a mind also has a body made of flesh and blood. But if we look at the diversity of animals found in the world, we find a huge variety of species that perceive and interact with the world in very different ways. Is there something all these species have in common? Are neurons and ganglia required, or can evolution generate consciousness in different ways? What can the study of evolutionary biology tell us about the nature of the mind? Josh and Ray sail away with Peter Godfrey-Smith from the University of Sydney, author of Metazoa: Animal Life and the Birth of the Mind.
How did evolution first produce minds?
How can we tell which living things are conscious?
I mean, what would it be like to be a shrimp?
