Presence of the Past

Biochemist Sheldrake maintains that if a pigeon in London learns a new habit, then pigeons everywhere else will automatically show an increasing tendency to learn the same habit. He holds that invisible energy patterns or ""morphogenetic fields'' surround and shape all atoms, all crystals, all pigeons and all humans. In his astonishing theory, any natural systemwhether insulin molecules, dandelions or societiesinherits a collective memory from all previous members of that group. Experimental evidence for Sheldrake's hypothesis is inconclusive but tantalizing. If true, it would force a radical revision of our understanding of genetics, evolution, memory, learning. Many books on the ``new physics'' and the paranormal have discussed Sheldrake's ideas, but his own explanation of morphic resonance is the most lucid and exciting account to date. He uses the theory here to suggest how creation myths and rituals connect past and present. (February)
