Caption: Both climate change and humans were responsible for the extinction of some large mammals, like the musk ox in this photo, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals. The large international team's research, which will be published in the journal Nature, is expected to shed light on the possible fates of living species of mammals as our planet continues its current warming cycle.
