When and where did consciousness emerge in the course of evolution? Did it happen as recently as the past million years, for example concomitant with language or tool making in humans or primates? Or did consciousness arrive somewhat earlier, with the advent of mammalian neocortex 200 million years ago (Eccles, 1992)? At the other extreme, is primitive consciousness a property of even simple unicellular organisms of several billion years ago (e.g. as suggested by Margulis and Sagan, 1995)? Or did consciousness appear at some intermediate point, and if so, where and why? Whenever it first occurred, did consciousness alter the course of evolution?

Humans are a part of the complex system including both natural and cultural-technological environment. Evolution of this system included self-amplifying feedbacks that lead to the appearance of human conscious mind. We describe the current state of the understanding of human brain evolution that stresses neurohormonal and biochemical changes rather than simple increase of anatomical substrate for the mind. It follows that human brain is strongly influenced by the state of the body and may operate at various levels of consciousness depending on its biochemical environment created by ingestion of various substances and by specific physical activities. Through the study of the widespread phenomenon of shamanism that uses mind-altering practices we argue that altered states of consciousness and non-local minds are not only real phenomena, but that they are products of natural evolution, valuable for human survival and development. Consideration of altered states of consciousness and broadening of the framework for understanding brain function beyond mechanistic interpretations is necessary to further develop human adaptations and provide a better way of fitting humans as parts of the interconnected system into the global and universal patterns.

An easily-accessible introduction is provided for theauthor''s book Enchanted Looms , which is reviewedelsewhere in this volume by Jesse Prinz and by MarcelKinsbourne, and also for the article Didconsciousness evolve from self-paced probing of theenvironment, and not from reflexes? , which alsoappears in this volume and which summarises theauthor''s more recent thoughts on consciousness.
