East Africa's Turkana Basin has been a hot savanna region for at least the past 4 million years -- including the period of time during which early hominids evolved in this area -- say researchers. These findings may shed light on the evolutionary pressures that led humans to walk upright, lose most of our body hair, develop a more slender physique, and sweat more copiously than other animals.
