In the Mesozoic era began to separate (rupture) melaluidua meridian (Europe, Africa and America; Africa & India) formation of the Atlantic Ocean and the IndianClimate and location of the climatic area has changed so very distinct from current climatic conditions.• Start times myosin climate area nearly resembles the current climate region• The most important climatic element is the size of the extreme climate
                                  climate change sharply great influence on the spread of plants• extreme climate and geological history of major changes in the vegetation world (extermination, migration, adaptation and evolution).• The area of ​​the least to climate change (Tropical and Subtropical Southeast Asia, South America Tropical) rich plant (20-40 thousand species).• The area most experienced climate change (Tropical Africa) Only 10 -15 thousand species of plants
