This means that we must adapt to the new conditions. In a community, some plants thrive, others are suppressed, others disappear, and others appear. The longer plant communities travel, the more significantly they transform. Animals can't help but change along with them. Or they die out. During the Ice Age, many isolated areas were formed. Ice, tundra, mountains, deserts — many obstacles must be overcome by the inhabitants of the land in order to conquer new lands. People could eat plants, herbivores, and predators, and they were able to equip their homes and use tools. Still, they were completely dependent on the environment. It is assumed that the inner enclosed seas and large lakes located south of the glaciation area expanded their limits during the cold season, and the water level in the oceans decreased (due to the formation of glaciers on land). The sea coasts and plains changed a lot (and it was here that life flourished).
For example, archaeologists note the similarity of the stone tools of Paleolithic people who lived in the Urals and Siberia, and their slight difference from the tools of the inhabitants of more western and southern regions; and later, in Neolithic times, there was a constant exchange of tools and labor skills between the tribes of Siberia, the Urals, Eastern Europe and the Caucasus; stone tools in all these The areas have become, in general, the same. Russian archaeologist O. N. Bader concluded from this that in Paleolithic times, the Urals and the Urals, with their wildlife and population, were like the western outskirts of Siberia and separated from Europe from the north by the great glacier, and from the south by the overflowing ancient Great Caspian Sea. Geologists studying the history of the Caspian Sea confirm the relative simultaneity of its floods (transgressions) and glacial advances. In the interglacial, in the "geological summer", adversity and isolation ended. Plants, animals, and tribes of people who had survived the invasion of the ice were now moving to new places, covering vast areas. New communities were being created. Relatively few surviving species of animals and plants dominated large territories. With sudden climate changes in each enclosed area, the old creatures quickly transformed and new ones appeared. This happened not only according to the laws of genetics and natural selection, but also according to the laws of interaction with the environment. Each area has its own geological features: an excess or lack of certain chemical elements, different rocks and minerals, the composition of soils and natural waters.
