How Humans Became Intelligent

How can humans pair bond when our sexual urges are always 'on?' Why did our ancestors build mounds--it wasn't to communicate with extra-terrestrial beings!

From the conditions that make genetic change occur in an eyeblink to building houses beginning 12,000 years ago, our path from instinct to intelligence has been an interplay of fortuitous timing and horrible weather. This easy to read, engaging book connects the dots of archaeological research, genetics and biology to outline the path a small ape took from tree-dwelling in the tropics to advanced education in brick-built colleges in only five million years.

In the history of life there has been only one inducement for greater intelligence in a species. This factor created three intelligence bumps for humans but only one for apes and dolphins. Using clear evidence and photos, Hartwig aligns our past with recent genetic revelations as well as our physical appearance, habits and diet.

This fascinating book dives into why we look the way we do, which is so different from other mammals. Why do we have ear wax? Why is our nose is shaped like this? How can kids instinctively obey a teacher? What do these say about our past? Read the book to find the answers to these and many more questions.
