Adapting zebrafish to warmer water temperatures (IMAGE)
Caption
In a long term experiment designed to mimic evolution over seven generations, researchers specially selected a group of zebrafish to tolerate warmer water temperatures. Anna Andreassen, who did her PhD research at the Norwegian University of Science and Technology (NTNU) on this project, is shown holding some of the participants from the experiment.
