Course content
Enviromental changes in the Earth history. Causes and impact of these changes to biosphere evolution: change from anaearobic to aerobic environment in the Precambrian, changes in ocean chemistry, the Cambrian diversification of marine biota, carbon revolution in the Devonian as result of the terrestrization, massive extinctions caused by climatic factors, biotic competition, volcanism, green-house effect, changes of geochemical chains and impacts of bolids. Changes in geochemical chains at present time. Quarternary extinction due the climatic changes and human activity. Evolutionary faunas in the Palaeozoic, Mesozoic and Caenozoic eras. Massive extinctions, "Big five". General aspects of extinction and recovery of marine and terrestrial ecosystems. Gaia as the theory of the Earth homoeostasis.
