David Hillis is an evolutionary biologist just outside of Austin Texas. From around 10 to 15 years ago, and up until now, Dr. Hillis began researching the evolutionary history of the Texas longhorn. The Texas longhorn is found all over Texas- becoming both a symbol of the state and a mascot. The cattle have evolved to grow horns that can pass 7 feet across. Dr. Hillis found that in addition to their massive horns, the Texas longhorns also have an unusual history.
The Texas longhorn was domesticated a while back, like most cattle. What makes their history unusual is they managed to become wild once more, allowing them to be domesticated twice. Through genetic testing and historic documentation, Hillis found the Texas longhorn descended from
