Using a technique called RASA, which pinpoints and eliminates "noisy," or inconsistent data, researchers led by Claude dePamphilis of Penn State helped determine that water lillies are among the oldest members of the famiy of flowering plants. That research, which can be found on page 22, has sparked much debate because water lillies feature two-sex blooms and other researchers had previously believed ancestral plants separated sex orgons onto different flowers.
