Dennis Chitty

Dennis Hubert Chitty FRSC (18 September 1912–3 February 2010), was a professor of zoology at the University of British Columbia. In 1969, he was elected as a Fellow of the Royal Society of Canada.^[1]

The Chitty Hypothesis of Population Regulation states that population density is limited by spacing behaviour, which has has genetic underpinnings and rapidly responds to natural selection.^[2] Because of the controversial nature of this idea at the time, David Lack attempted to veto Chitty's dissertation, though it was eventually accepted because of the intervention of Peter Medawar.^[3]
