Genes may travel from plant to plant to fuel evolution
Providence RI (SPX) Feb 21, 2012
The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way. But evolutionary biologists from Brown University and the University of Sheffield have documented another avenue, through the passing of genes from plant to plant between species with only a distant ancestral kinship. How this happened is unclear. But the researchers show that not only did a grouping of grasses pass genes ... read more
