Jack Hills
The Jack Hills are a range of hills in Mid West Western Australia. They are best known as the source of the oldest material of terrestrial origin found to date: zircons that formed around 4.4 billion years ago. These zircons have enabled ground-breaking research into the conditions on earth in the Hadean eon. In 2015, "remains of biotic life" were found in 4.1 billion-year-old rocks in the Jack Hills of Western Australia.〔 Early edition, published online before print.〕 According to one of the researchers, "If life arose relatively quickly on Earth ... then it could be common in the universe."〔 ==Geography== They are located on the border of the Shire of Murchison and the Shire of Meekatharra, south of the Murchison River, about north of Perth.
