1. Check the meaning of the words in blue in the text. Then look at the photos. What kind of animals are these? What do you think happened to them?

What happened to the mammoths?

1. Every day, species around the planet are becoming endangered because of climate change and human activities. Some animals, like the snow leopard, the saiga antelope, the steppe eagle and the Caspian seal, are so critical that they are threatened with extinction. Others have already become extinct, like the Caspian tiger, the cave lion, the aurochs and the Siberian unicorn. During the Ice Age, herds of mammoths, steppe bison and Hipparion horses wandered the steppes of Central Asia, but they all disappeared thousands of years ago. So, what exactly happened to these animals? And how do we even know they existed or what they looked like?

2. Palaeontologists are scientists who study the fossils of plants and animals that lived long ago. They have found evidence that there was a global extinction of very large mammals at roughly the same time when humans expanded around the world, and many scientists believe that the two events are connected. Mammoths and steppe bison were hunted by prehistoric humans for food, for their fur and their bones. The fur was used for making clothes and the bones were used for making tools, weapons, decorations and even houses. Fossils aren't the only evidence in support of this theory. Prehistoric people painted pictures of hunting scenes with mammoths, bison and other animals on cave walls and rocks around the world.

3. Another theory is that this mass extinction wasn't caused by hunters but by changes in the environment. Towards the end of the last Ice Age, about 15,000 years ago, the weather started to change and the larger mammals couldn't adapt to the higher temperatures. Many of them lost their habitats and migrated north, where they died because they couldn't find enough food. Scientists have discovered numerous fossils of mammoths and other prehistoric animals in Siberia and the Arctic. They are hoping that by using DNA from these fossils, we could one day clone a mammoth.

2. These animals are mammoths.

Эти животные - мамонты.

3. I think they went extinct. According to the text, one theory is that people hunted them until there were no more left. Another theory is that the weather got warmer after the Ice Age, and they couldn't survive in the new climate. Maybe both things happened!

Я думаю, они вымерли. Согласно тексту, одна из теорий гласит, что люди охотились на них, пока их совсем не осталось. Другая теория говорит, что после Ледникового периода погода стала теплее, и они не смогли выжить в новом климате. Может быть, произошло и то, и другое!
