Who is conscious? Initially it was thought just humans, then primates, all mammals, birds, and now evidence is found in the simplest of organisms. This guide follows the development of consciousness through the human life stages, before tracing how it presents itself in mammals, birds, fish, and other creatures down the phylogenetic tree. Different philosophical, psychological, and spiritual theories, approaches, and perspectives are investigated and integrated into a wholistic view of what consciousness is, what it's evolutionary benefits are, and how meditation and other practices can alter the way we experience it.
