From about 200 to 300 million years ago, all seven of the continents today were pushed together as one hung landmass, known as Pangaea. Since that time, the continents have “drifted" away from of each other due to the movements of the Earth's crust. The moving parts of Earth’s crust are known as the tectonic plates. Scientists began noticing separate continents puzzle-like pieces and began looking for answers. Just look at how eastern South America tucks into western Africa!
For thousands of years, most of mankind existed in total isolation on the continent of Africa. If Pangea had not split up, humanity would have still spread formed countries.

Countries that invaded other countries couldn’t bring strange and foreign germs if none existed! Every country would have the same immunity and the same diseases (which is both a blessing and a sin).
The life on Pangea would be far less diverse. The biggest part of new speciation from the development of old species stems from geographical isolation. Consider the large island of Madagascar, which broke off from Gondwanan about 160 million years ago (Gondwanan was the southern half of Pangaea). About nine out of ten of the mammal and plant species that evolved on the island cannot be found anywhere else on the Earth!
A locked-in Pangaea would constrain life's possibilities since much of its interior would be hot and arid, "Because of Pangaea's size, moisture-bearing clouds would lose most of their moisture before getting very far inland," Damian Nance, a geoscience professor at Ohio University, told Life's Little

evidence due to major gaps in the PTB boundary layers. Also marine faunal evidence is much more linear than terrestrial. Yoram Eshet et al.
