  Houston TX (SPX) Jul 24, 2018 Scientists have long thought oxygen appeared in Earth's lower atmosphere 2.7 billion years ago, making life as we know it possible. A Rice University researcher has added evidence to support that number. The sulfur record held by ancient rock marks the dramatic change in the planet's atmosphere that gave rise to complex life, but rocks are local indicators. For the big picture, Rice biogeochemist Mark Torres used water that flows over and erodes the rocks as a proxy. Torres, a Rice assistan ... read more |
