Would history be different, because knowledge could spread far more easily? Since Europe and Asia have similar climates over long regions, in compare to South America, North America and Africa which have different climates over short regions?
What I mean for anyone who is confused is, what if the continent was like this?

Instead of like this:

This has always been on my mind
Thanks






This is an excellent idea! Alternative suggestion to a Sahelian zone, that would bump into India and all, is one at the level of South Africa. The climate is more temperate here, akin to Mediterranean climate. Using chunks of Antarctica, it could perhaps be extending as far as Australia. This is also reminiscent of an Alternate History scenarion I've been pondering about Terra Australis, that was thought to "counterbalance" the Northern continents.
Very creative topic! I think that it would definitely have a dramatic influence on the development of Africa. However, I think it would be worth nothing that the biggest influence would probably come if this "horizontal Africa" was located in the area that is now the Sahara (let's also say that it was more of a grassland than a desert). Sahlian civilizations grew relatively large and advanced compared to most other parts of sub-Saharan Africa. With that said. I could easily see a "Sahelian Empire" evolving out of this new continent due to the ease of transmission of ideas and technology in addition to no desert barrier.
