Duocontinental World

So, most of us know there are seven continents today: Europe, South America, North America, Asia, Africa, and Antarctica, but what would it be different if there would be only two, which for the sake of simplicity I'm gonna just call Uno and Duo, but then let's just start with it, if you want to contribute in the future, feel free to do that

70000:

Two human species exist independently on Uno and Duo, both being a little different, both in culture and intelligence, humans from Duo are the less intelligent with 80 IQ as normal, and people from Uno have a much larger 100 IQ as their normal, but both being smaller than a modern day human.

50000:

The two humans meet the first time, and a common specimen is created with 125 as the normal IQ, but the other species are not extinct.

20000: The Duan human is extinct, but there is still a number of the Unan species.

17000: The Unan species merge with the modern human, which has evolved and now has 129.99 IQ as normal.

13000: Agriculture is created, but no larger human settlements so far



5000: Banners are invented and commonly used in rituals by the Ana, also more cultures emerge like for example the Teapolian culture in south Uno, having similar traditions to real life Christianity, and Thamiont culture on both east and west Duo

3000: The Ana invents a really humble version of writing with 100 glyphs

1500-1450: The first recorded war happened between the Ana Empire and the Holy Teapolitan Empire, the Ana Empire wins and the Holy Teapolitan Empire falls apart into many smaller nations, most notably Chewig, and Teapoli (formal capital of the empire as a city-state)

500: The Teapolitans develop their own writing system based on the Ana one, but with only 70 glyphs and two joint-glyphs which are used to show the relations between two glyphs 350: The Thamiont civilization on southern Duo forms the Thamiont Tribal Alliance, in which Thamiont tribes are united with each still having some autonomy, the Thamiont civilization is the first to build ships, too. 150: Middle Ana culture, first ships built on Uno, knowledge of iron, and invention of windmills.

100: The Ana discovers Terra Norde, the northernmost piece of the world (on the top left side of the map), which was the only place where humans did not get to before. They establish a settlement called New Quadropoli, and send back a ship to inform the empire of new land, but the ship has crashed into an iceberg and never came back, which have resulted in complete isolation.

77: Terra Norde develops its own writing system, the first one to use letters instead of glyphs.

1 AD: The Thiamont develops a writing system with glyphs, but they are much simpler than usual.

5 AD: Terra Norde develops their own culture that was highly influenced by the Ana, the most notable differences are that the four-edged star is a known symbol, and they have dropped the tradition of banners.

50 AD: New Quadropolitans try to find the long-lost mainland that is now mostly taught about as a legend about them, the ship arrives back five days after it with the king of the Ana Empire, and alliance is declared between the two nations.

100 AD: Late Ana culture, New Quadropoli reaches the population of 50,000, high amount of trade and cultural exchange happens between New Quadropoli and The Ana, too.

150-200 AD: The Teapolitan Empire reunites and war starts between them, the Teapolitan Empire wins, the Ana Empire falls, but their culture still exists.

210 AD: The Teapolitan Empire disunites again because it had grown too large and it was uncontrollable, it split into 20 countries.
