Columbus' voyage marked a unification of the two worlds that had been existing on Earth. People living in AfroEurAsia and the Americas may have encountered each other before that but not much came of it. 
After that voyage, the 2 worlds started on a course that would share ideas, people, plants and everything about the civilizations with the whole planet.
