Scientists Use Fossilized Emu Eggshells To Discern Changes In Vegetation, Provide Additional Evidence Of Human Impact On Australian Landscape

...For instance, plants with less leaf area wouldhave reduced evapotranspiration, in which plants give off moisture to theatmosphere. This is moisture that would have contributed to additional rainfallinto the continental interior. Soils would have had less organic matter andless ability to hold moisture. Fir...
