Scientists replicate key evolutionary step in life on earth

Hey Guys,Another step forward for the science guys -More than 500 million years ago, single-celled organisms on Earth's surface began forming multi-cellular clusters that ultimately became plants and animals.Just how that happened is a question that has eluded evolutionary biologists.Now scientists have replicated that key step in the laboratory using common Brewer's yeast, a single-celled organism.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.rest of the story here - http://www.physorg.com/...plicate-key-evolutionary-life.htmlYay for us!
