Scientists unveil a new Tree of Life
“Bacteria dominate newly drawn tree of life
Scientists at the University of California at Berkeley and the University of Waterloo in Canada studied more than 3,000 species and pieced together bits of DNA to update the tree of life. The tree is dominated by bacteria, while all the eukaryotes are represented on a slender twig. The work is published in the journal Nature Microbiology.” The New York Times (free-article access for SmartBrief readers) (4/11)

Life on Earth, 4.1billion years old?
Life on Earth likely started 4.1 billion years ago, much earlier than scientists thought
Posted: 19 Oct 2015 12:41 PM PDT
“Geochemists have found probable evidence for life on Earth at least 4.1 billion years ago — 300 million years earlier than previously documented, pushing the origin of life close to when the planet formed, 4.54 billion years ago.
