Recent debates surrounding the teaching of biology divide participants into three camps based on how they explain the appearance of the human race: evolution, creationism, or intelligent design. Biosemiotics discovers an intriguing higher ground respecting those opposing theories by arguing that questions of meaning and experiential life can be integrated into the scientific study of nature. This groundbreaking book shows how the linguistic powers of humans imply that consciousness emerges in the evolutionary process and that life is based on sign action, not just molecular interaction. Biosemiotics will be essential reading for anyone interested in the nexus of linguistic possibility and biological reality.
