Wooded Grassland Savanna

Caption

Giraffes roam in a wooded grassland savanna in Kenya's Nakuru National Park. The savanna grades into the woodland in the background. University of Utah researchers developed a new way to use fossil soils to determine the amount of tree cover in prehistoric landscapes. They conclude savannas predominated East Africa's landscape during some 6 million years of evolution of apes, human ancestors and humans.
