If the world were still a massive supercontinent like Pangaea today, how would humanity be different?

I am wondering what kinds of differences we would see in areas such as: war, politics, culture, scientific development, etc.

    1. There would be a huge desert in the middle. This would really mess up the air currents around earth. Most of this land would be inhospitable. That means less hospitable land, and we would all be a little short on food.

    I think it would also have changed humanity itself.

    1) Dawn of Civilization. Assuming once again that homo sapiens are able to evolve and survive, let's say for fun around the savannas of Northern "Africa", and would spread out across the globe, albeit slowed by mountains and passes. Some would head north to a fertile crescent 2.0, likely around lands that in our reality, became Greece, Italy, and central Europe. These people would thrive in a dawn to civilization not unlike our own...though perhaps hunted by 20 ft. Carnivorous Elephant-like creatures.
    2) Technology. Since a great amount of the more central parts of the supercontinent would be desert (though with climate change patterns it could vary), major agricultural and later industrial-based societies would flourish along the seaboard, where great populations of people would be able to communicate and share information/discoveries much more easily than our own jagged world. Eventually, as trade built up around the Eastern seaboard (which would help it flourish), some king or queen would likely give a grant for some intrepid ocean-faring explorer to take their mighty vessel out to cross the great eastern sea beyond the lands that are now China to find quicker passage. Unluckily for the intrepid explorer, the Americas are not there to save the ship in this reality, and everyone who ventures out to sea beyond China is never heard from again. Due to this, it is many years before mankind indeed proves that the world is round, and potentially not even by circumnavigating it.

    And if any type of life forms ventured onto the land & evolved into a human type form.
    Your question is a huge one and there are a world of variables to take into consideration.
    But, if by some chance humans did evolve, I suspect you would still have greed as the driving force. Which is, pretty much, what you have today, just that your neighbors are closer.

    But wow, what a different world it would be! I wonder where we would be living.
