A team of ecologists, biologists, geographers, geologists and Earth scientists from across Europe, working with a colleague from the U.K. and another from Canada, has found evidence suggesting that Europe was not covered heavily by forest during the Last Interglacial period, as many have suggested, but was instead half grassland. In their project, published in the journal Science Advances, the group studied pollen samples collected over many years at dig sites across Europe.
