Biologic carbon found in 4.1 billion-year-old zirzon - Wendy Mao

A set of 47 human teeth found in China dated to 80,000-120,000-years-old, described in a paper published on October 14, 2015, in Nature, bear a close resemblance to those seen in modern humans. Then another study co-authored by Wendy Mao, a scientist of HPSTAR, also indicates evidence of life on earth from the carbon isotopes in 4.1 billion-year-old ziron crystals. The research was published recently in PNAS. These evidence of life may rewrite early earth history as well as human history.
