I've read that the "Bre'r Rabbit and Tar Baby" story which was popularized by 'Uncle Remus' has its source in a traditional West African folktale-I think Nigerian*. But I can't give any citations for that information right now.

*This is not to say that there weren't American Indian stories or stories from other people which were similar. It's just that rabbit stories were particularly plentiful among the Yorubas and other Nigerians (while spider stories such as Ananse were more common among the Akan in Ghana, West Africa). When I was much more active as an African Storyteller than I am now, I was able to rattle off the African source for this story and that story itself.

But unfortunately that was then and not now.
