[Star Wars] What planets did humans evolve and learn space travel on? Why are humans so prevalent in the galaxy when other species seem under represented?

Ultimately, it is unknown, but most believe that Coruscant is the original birthplace of Humanity. Our prevalence has been a point of contention between anthropologists since the beginning, but a popular theory relates to our being used as a slave race for an ancient empire. It is believed that we were shipped to every corner of the galaxy and, presumably, left to our own devices after the fall of this empire. Being a naturally inquisitive and adaptable race allowed us to make very early use of reclaimed hyperdrive technologies, further cementing our presence throughout the galaxy. 

On top of that, we reproduce quickly and can adapt to most environments, which allows us to be found in such high numbers basically everywhere you look.
