...They returned at nightfall to sleep in the open, curled up together in - Adrien's oversize sweater. "I am hungry and my head is hurting," he says, wiping flies from his swollen eyes. Neither child has eaten in two days, and Adrien is running a high fever, probably from malaria...
...would adhd have evolved in the first place? Perhaps, like the sickle-cell trait, which can help thwart malaria, attention deficit confers an advantage in certain circumstances. In Attention Deficit Disorder: A Different Perception, author Thom Hartmann has laid out a controversial but appealing theory that the characteristics known today as adhd were vitally important in early hunting societies. They became a mixed blessing only when human societies turned agrarian, Hartmann suggests. "If you are walking in the night and see a little flash, distractibility would be a tremendous asset.

On the Vietnamese side, even native hunters rarely remain long in the forest; instead they catch game by setting snares or by using dogs that chase animals down to the slightly more accessible riverbanks...

One reason: because of what science now knows is the sickle-cell trait, blacks were often less susceptible than whites to the depredations of malaria. More important, a terrible distinction had been made, first informally but then in legislation: white servants were considered persons despite their temporary state of servitude; blacks were mere property that could be bought and sold...
