The little I know about this is from an old issue of Spektrum der Wissenschaft where there was an article about comparison of syntax in various creole languages, and the point was that all creole languages have the same syntax, and it does not matter which language is the mother language; it could be English, Spanish, Portuguese, or even Chinese (if I remember correctly).For example, in the previously mentioned case of creoles, Pinker seems to be relying on Bickerton's work which is not by any means established fact. Some linguists (such as Dell Hymes) think that the grammar of creoles are basically derived from one of the parent languages and not, as seems to be suggested, created by child native speakers of creole.
I might be able to locate the issue, if pressed, but not right away!
