  • The continents haven't always looked the way they are.

  • Hopefully, this isn't a new fact for you.

  • Over the vast lifespan,

  • Earth has mashed its land masses together.

  • In fact over 300 million years ago,

  • all the Earth's continents were connected into one large supercontinent

  • called Pangea.

  • Surrounded by one superocean

  • called Panthalassa.

  • For over a 100 million years,

  • the Earth had only one continent

  • and one ocean,

  • until breaking up and eventually forming the continents we see today.

  • Booo!

  • What if in alternate timeline,

  • Pangea still existed?

  • The continents simply never broke apart

  • and if humans were rose to spread across the world.

  • How would civilization be affected?

  • Before answering these questions,

  • we need to discuss a few facts.

  • This is all theoretical.

  • If Pangea was still around,

  • it's best to assume humans wouldn't be.

  • Evolution is a cause and effect process

  • affected by the environment and geography.

  • The simplest change in climate

  • can affect the lineage of a species

  • forcing them to adapt or to go extinct.

  • Without an Africa factor for apes to be able to rise,

  • homo sapiens ancestors would have gone down a much different alternate path.

  • This said, we can still place humans on Pangea for the sake of the theory.

  • Plus, it would be boring without us.

  • Humans are resourceful

  • and would be able to spread and conquer this Pangea world.

  • But geographically, what would this planet look like?

  • Pangea specifics are a mystery to us.

  • We can only get a basic look of what its shape was

  • and hypothesize form there.

  • Unlike today,

  • where most land is in the Northern Hemisphere,

  • most land on Pangea was south of the Equator.

  • Long mountain ranges rose in the center of Pangea from connecting continents.

  • Similar to India pushing up against Asia,

  • creating the Himalayas.

  • Because of these mountains,

  • arid desert landscapes formed due to lack of rainfall.

  • It's been theorized, mega monsoons swept from the oceans

  • and brought rain to the equatorial regions.

  • This would replenish the vast rainforests which spanned the Equator,

  • which is present day North America in western Europe.

  • Fun Fact!

  • A lot of that coal used to bring

  • Britain into an industrial age

  • and mine in West Virginia,

  • was from the lush tropical forest millions of years ago.

  • Yay! Science!

  • Back on track,

  • human civilization would be drawn to the coastline

  • just as in our timeline.

  • No surprise.

  • Tribes in Nomadic people

  • would roam in the less hospitable lands.

  • Even if all of humanity share the same continent,

  • this does not mean they would be more connected.

  • If large deserts or rainforests did form in the center of Pangea,

  • they would just be as limiting to communication

  • between people as any ocean would be.

  • We see this in Africa,

  • Sub-Saharan Africa is connected to Asia,

  • just as it is with Europe.

  • Yet there was much less communication.

  • Very little trade occurred,

  • not counting East Africa and Madagascar.

  • Parts of Sub-Saharan Africa

  • were almost the equivalent of the Americas

  • in its isolation.

  • Which is why tribes like the Zulus

  • still use spears up against British machine guns.

  • This was because of the natural barriers

  • of the Saharan desert and the Congo jungle.

  • Both regions were very difficult to cross

  • before the Industrial Revolution

  • and create a rift in communication

  • between civilizations of East Asia and Europe

  • with Sub-Saharan Africa.

  • The point is

  • we could still see the same effects in Pangea.

  • Deserts could split east and west,

  • while the equator rainforests could split north and south.

  • Present day North America and Eurasian peoples

  • could develop a culture independent of South American,

  • African and Australian people.

  • This is all theoretical though,

  • there is no hundred percent accurate way

  • to predict how things would have been.

  • This was just my two cents on the matter.

  • Pangea itself is much of a mystery,

  • but it's always fun to explore the possibilities and geography.

  • What do you think the world would be like if Pangea still existed?
