In this video, we are going to find out how animal bones found in an island cave in the Adriatic Sea, tell us about the movement of people during the last glacial maximum from research carried out by Pierre Spry Marquez. 23000 years ago towards the end of Old Stone Age, also known as the Upper Palaeolithic, the weather in Europe and in many parts of the world took a turn for the worse, temperatures plummeted, rain levels fell and a massive ice sheet slowly advanced to cover most of northern Europe and stay there for the next few thousand years. We know that during this glacial period, many animal and plant species sought shelter in Europe’s three warmer southern peninsulas: Iberia, Italy and the Balkans, but the question is where did the people go. Archaeological material recovered from this time period has shown that a large number of our ancestors retreated to Franco Cantabria and area covering the southwest of France and North-eastern tip of Spain, but was this the only area where people travelled to to escape the worst of the weather. Let’s go back to the growing ice sheet, in order to grow, the ice mass had to take up water, causing sea levels to fall at its maximum when the ice reached as far south as Germany, sea levels were up to 120 meters lower than today, that’s approximately the same height as the London eye. As a result, areas of shallow sea became exposed and Europe’s shape was very different to the one we recognized.
