Scientists have discovered molecular tools that may have aided the emergence of complex life forms around 700 million years ago. They successfully tested these tools by generating mouse stem cells from a single-celled organism, a step towards understanding how our ancestors came to be. The breakthrough allows researchers to form living mice using these ancestral cells, shedding light on the evolutionary process.
