Abstract
<p> <ul> <li> Recent analyses have identified more than 500 stretches of DNA that were lost from the human genome but still exist in chimpanzees and other mammals. </li> <li> Three stretches appear to be DNA switches, and loss of two of them freed brains to grow and humans to evolve pair bonding with mates. </li> <li> Loss of another switch from our ancestors may have refined our upright gait, which freed our hands to make and carry tools. </li> </ul></p>
