What if Pangea never broken apart?

Hello guys, in this article we are gonna see what would have happened or what would have been the changes in our earth's atmosphere if pangea(the massive continent) never broken apart.

From about 300 million to 200 million years ago, all seven modern continents were mashed together as one landmass, dubbed Pangaea . The continents have since drifted apart because of the movements of the Earth's crust, known as plate tectonics. Some continents have maintained their puzzle piece-like shapes: Look at how eastern South America tucks into western Africa.

Life would be: Far less diverse. A prime driver of speciation the development of new species from existing ones is geographical isolation, which leads to the evolution of new traits by subjecting creatures to different selective pressures. Consider, for example, the large island of Madagascar, which broke off from Gondwana, Pangaea's southern half, 160 million years ago. About nine out of 10 of the plant and mammal species that have evolved on the island are not found anywhere else on the planet, according to Conservation International.

A locked-in Pangaea further constrains life's possibilities because much of its interior would be arid and hot, said Damian Nance, a professor of geosciences at Ohio University. "Because of Pangaea's size, moisture-bearing clouds would lose most of their moisture before getting very far inland," Nance told Life's Little Mysteries.

Excess mass on a spinning globe shifts away from the poles, so the supercontinent would also become centered on the equator, the warmest part of the planet. Reptiles could deal with such a climate better than most, which is partly why dinosaurs, which emerged during the time the planet's surface was one giant chunk, thrived before mammals.
