The Chitty Hypothesis of Population Regulation states that population density is limited by spacing behaviour, which 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]
