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
