Ancient DNA Provides the Clue to Modern Cattle

Modern dairy cows are as elite as Olympic athletes. They are champion milk producers and enable humans to turn fodder into dairy food with incredible efficiency. Underlying this performance is thousands of years of selection and improved management practices. Initially, the selection process was farmer driven and resulted in the development of many cattle breeds, but since the mid 20th century, when coordinated efforts by farmer groups and the dairy industry focused attention on the best methods to achieve improvements in production, the gain in efficiency through genetic selection has been remarkable.

Ancient Aurochs Genome Contains the DNA Blueprint for Modern Cattle

Ancient Aurochs Genome Contains the DNA Blueprint for Modern Cattle

A preserved specimen of aurochs bone was discovered deep beneath the Derbyshire Dales in the UK in the 1990s. Aurochs are an ancient cattle breed domesticated around 10,000 years ago somewhere around modern day Iran. In Europe, the last of these animals were still found on a Polish royal reserve as recently as the 17th century. Park et al., have now extracted enough DNA from the ancient bone specimen to sequence the aurochs genome. When they compared the aurochs sequence to the DNA of cattle breeds we know and use in domestic agriculture today, they found a surprisingly high level in common with British and Irish cattle.
