Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g Life - Using high-resolution satellite mapping, scientists have discovered that there are twice as many emperor penguins in Antarctica than was previously thought. See article.g Intelligence - Carnivory is behind the evolutionary success of humankind. When early humans started to eat meat and eventually hunt, their new, higher-quality diet meant that women could wean their children earlier. Women could then give birth to more children during their reproductive life, which is a possible contribution to the population gradually spreading over the world. The connection between eating meat and a faster weaning process is shown by a research group from Lund University in Sweden, which compared close to 70 mammalian species and found clear patterns. See article.g Cosmicus - Rocks from Mars can teach us much about the red planet - its geology, its climate, and whether or not it ever hosted life. A new study says that looking for evidence of past life on Mars should be one of the driving forces behind a sample return mission. See article.Get your SF book manuscript edited Amazon.com Widgets
