The island was also occupied during later periods, and Stone Age bones have been analysed to investigate what people were eating. The Mesolithic bones suggest a very high sea diet - up to 70% of the diet - but by the Neolithic, they're not eating fish. This provides strong evidence that the transition from hunting and gathering to farming happened quickly - possibly within a hundred years. However, it's not clear whether farming was brought in by people from other parts of Britain and the continent or whether it was adopted in the Neolithic by local people.
