De Waal Traces Human Behavior to Apes
Humans may have more in common with monkeys, chimpanzees and other non-human primates than they think, according to Frans de Waal, C.H. Candler professor of primate behavior… Describing social reciprocity, de Waal explained that the way humans elect their political leaders mirrors the way an alpha male gains power. Chimpanzee dominance is not determined by strength or size. Rather, a highly organized coalition of animals must support, or elect, their leader.
De Waal’s findings would be featured in my book, if I could ever find a publisher.

Monumental Human Voyages Revealed by Obscure Tool
During the Stone Age, early humans chipped away at hunks of rock to make hand-held adzes which were probably used to butcher animals or fashion other tools. The Egyptians refined the adze by making it from metal and then mounting the blade on a wooden handle. Other cultures made their adzes out of whatever was at hand—shell, wood, bone—anything that would slice and dice. The adze can also be a key to mapping ancient human migrations because it’s portable.
