The resulting chimera mouse confirms that single-celled organisms had the biolgical tools to develop specialized cells before the creation of stem cells and the entire animal kingdom. What’s the ...

This unexpected discovery challenges a longstanding belief that these genes evolved exclusively within animals. "By successfully creating a mouse using molecular tools derived from our single ...
