![]() The yeast "evolved" into multi-cellular clusters that work together cooperatively, reproduce and adapt to their environment-in essence, they became precursors to life on Earth as it is today. Now scientists have replicated that key step in the laboratory using common Brewer's yeast, a single-celled organism. Just how that happened is a question that has eluded evolutionary biologists. More than 500 million years ago, single-celled organisms on Earth's surface began forming multi-cellular clusters that ultimately became plants and animals.
