Piperno, Klaus and their team were also interested in seeing how a noticeable spike in temperature and CO2 that occurred between the late Pleistocene and Holocene eras may have influenced plant productivity, and could help to explain a possible reason for why agriculture began during that time and not before. But in potential for fueling food-price inflation, did come to the attention of Piperno plans to continue her research by conducting artificial selection studies, growing several generations of plants to observe the inheritance of the induced, maize-like phenotypes.
