An interdisciplinary group applied the latest tricks of phylogenetics — using genes and genomes to build evolutionary trees — to trace all of modern life back to our shared ancestor.

The work suggested that LUCA was a surprisingly complex cell and dated LUCA to some 4.2 billion years ago — earlier than researchers had thought.
