Rethinking Snowball Earth and potential for past life on the Red Planet

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - A new study suggests that geochemical records found in rocks prior to the glaciation event known as Snowball Earth are unrelated to the glaciation itself. See article.
g Intelligence - Genetic mutations that boost an individual's adaptability have greater chances of getting through to X chromosomes - at least in chimpanzees, according to new Danish research. See article.
g Cosmicus - Eight years after landing on Mars, NASA's Opportunity rover is still returning important data about the potential for past life on the Red Planet. Five months ago, Opportunity reached Endeavour Crater, where it discovered geological deposits that are older than anything the rover examined in its first seven years. See article.
