Researchers create largest evolutionary ‘timetree’ of land plants to investigate traits that permit survival in cold climates

A team of researchers studying plants has assembled the largest dated evolutionary tree, using it to show the order in which flowering plants evolved specific strategies, such as the seasonal shedding of leaves, to move into areas with cold winters. The researchers, including University of Minnesota professor Peter Reich, will publish their findings Sunday, Dec. 22, in the journal Nature.
