【PTE干货】PTE 高频summarize spoken test精析 （十三：Ice age）
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 Marcus. 22,000 years ago, towards the end of old stone age, also known as the paleolithic, the weather in Europe and in many parts of the world took a turn for the worse, temperature plummeted, rain level fell and massive ice sheet slowly advanced to cover most of northern Europe, and stayed there for the next few thousands of years. We know that during the glacial period, many animals and species sought shelter in Europe’s warmer southern peninsulas, Liberia, Italy and Balkan. But the question is, where did the people go? Archaeological remains recovered from this time period has shown that a large number of our ancestors retreated to …, an area that covered the southwest of France and north-eastern tip of Spain. But they weren’t the only areas where people travel to, to escape the worst of weather. Let’s go back to the growing ice sheets, in order to grow, the ice mass has to take up water, causing sea levels to fall. At its maximum, when the ice reached far south of 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 shape was very different from the one that we recognize. It could be that humans lived on these exposed shores during the paleolithic, but we have no evidence of their settlement because now they are under water.

This lecture introduces the reasons why we can’t identify human migration during the paleolithic period.
The speakers mentioned that 22,000 years ago, the weather in northern Europe became extreme with temperature plummeted and rain level fell. Many animals have moved to the warmer peninsulas. Because of the expanding ice sheet, sea level decreases. There weren’t any human remains because our ancestors were living on the exposed shores, which are currently under water.
In addition, the glacial period lasted for several thousands of years.
