The Steppes and Tundras of prehistoric Europe by James Geikie Book Summary

We are all familiar with the general conclusion arrived at by geologists that our earth has experienced many climatic changes. There have been times when genial conditions ranged up to the highest latitudes, and times also when the cold of the arctic regions descended to what is now our temperate zone. The cause or causes of those remarkable vicissitudes still baffle research. Many explanations have been advanced, some highly improbable, others perhaps more likely, while of yet others it may be said that possibly they contain a certain amount of truth. But no one theory or hypothesis has succeeded in gaining general assent, and we shall not therefore at present concern ourselves with any. In place of reviewing hypotheses and speculations, I shall limit myself to a survey of certain facts connected with the later geological history of our continent, the meaning of which is more or less apparent. The evidence referred to leads to the conclusion that Middle Europe has within the human period experienced conditions such, as now obtain in the tundras and barren grounds of circumpolar regions. When these conditions passed away, the central and west-central areas of our continent became steppe lands, comparable as regards climate to the subarctic steppes of southeast Russia and southwest Siberia.
As geologists reason from the present to the past, it will be well to take first a brief glance at those regions of the globe where at present tundra and steppe conditions respectively prevail. When we have realized the salient characters of those regions, and the nature of their floras and faunas, we shall be in a better position to understand the bearing of the geological evidence.
