I have never read this article you talk about here. This story is common among my people here in Africa and I was told this story back in my village when I was in primary school and a whole lot of other stories too.
This article here says she got it from Africa. Why can't we write our own story simple because someone from a foreign land took it from us and published it?
I wrote this article on my own, I have more than a 100 stories to tell about the tortoise, we Africans are known for that so please and please, I did not plagiarize.
