Black cottonwood trees (Populus trichocarpa) can clone themselves to produce offspring that are connected to their parents by the same root system. Now, after the first genome-wide analysis of a tree, it turns out that the connected clones have many genetic differences, even between tissues from the top and bottom of a single tree.
“The variation within a tree is as great as the variation across unrelated trees,” says Ken Paige, an evolutionary biologist at the University of Illinois at Urbana-Champaign, who led the team that made the discovery.
“This could change the classic paradigm that evolution only happens in a population rather than at an individual level,” says Brett Olds, a biologist in Paige’s laboratory, who presented the research at the 2012 Ecological Society of America Annual Meeting in Portland, Oregon.
