Keith Jensen is a lecturer in something like psychology at the University of Manchester. But he is really a biologist in disguise. In his previous life, he worked from the Yukon to Sable Island off eastern Canada, with animals ranging from small aquatic invertebrates and slightly larger fish, to voles and hares, to foxes and wolves, and to seals. His latest work is on chimpanzees and other great apes, including human children, all in captive environments (zoos and schools respectively).
