Evolution of life on land and half of population believes ETI has visited us

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 - Impurities in diamonds could help tell the story of Earth's ancient past. By studying mineral inclusions in diamonds, researchers have discovered that continents began breaking apart, drifting and colliding about 3 billion years ago. See article.
g Life - The chance discovery of agenetic mutation in wild barley is changing knowledge about the evolution of life on land. See article.
g Imagining - There’s some good news (at least for scientists and rationalists) in a new Gallup poll: When asked "do you believe that extraterrestrial beings have visited Earth at some time in the past," 51% said no. That fraction has risen. In a 1990 poll, 41% said no, and in 2001, 38%. See article.
