200 million years ago, all the emerged lands of the world were united in a single continental block, which today we call Pangea . Since then, various masses have been separating due to the movements of the tectonic plates present in the earth's crust to form the current continents.
If it had not been so, the conditions of the planet and its inhabitants would be very different. That single gigantic rotating continental mass would be located in the area of the equator, so temperatures would be high all year round, and mammals would not have evolved so dominant.
There would be strong storms, hurricane-force winds and waves of more than 30 meters high. The vegetation and most of the fauna would be concentrated on the coast, while in the arid interior, where the thermal variation would oscillate between 60 ° C during the day and -30 ° C at night, insects, reptiles and amphibians , capable poikilothermic animals, would predominate. to regulate your body temperature.
In the ocean, as the water moved away from the coast, the temperature would drop , so that the icebergs would be very abundant at the pole, which would increase the salinity and hinder the development of life. There would be less biological diversity, since isolation accelerated evolution in places like Madagascar or the Galapagos Islands, where many species are exclusive.
