Kathryn Lord began rearing wolves in 2004 under the guidance of Jacinthe Bouchard, a noted animal behaviourist in Quebec. Lord was a grad student researching how dogs and wolves develop during the first weeks of life. By then she was set on her path. It began in her freshman year at Hampshire College in Massachusetts. In her first semester she signed up for a course in animal behaviour. Her professor was Raymond Coppinger, an influential thinker in the field of dog domestication. For Lord, an evolutionary biologist at the University of Massachusetts Medical School, the mysteries of dog evolution still fire her curiosity. While the genetic difference between dogs and their wolf ancestors is small, the behavioural differences are vast.
