I know there were Zhell and Taung civilizations inhabiting coruscant about 200,000 bby, Zhell being "possible" Human ancestors and the Taungs are rumored to be the near human original Mandolorians, but this is before the Humans made there first hyperdrive's based on the Rakatan design, so maybe they did originate on multiple planets, Archaeologists have stated that due to coruscant's constant building and expansion, the lowest level is only 100,000 years old, making it impossible to find traces of the planets beginings...
