The fullest study of twin languages (also called autonomous languages)is Bakker (1987), on which I rely heavily here.
Bakker's conclusion on examining the grammars of twin languages is that the grammars are not necessarily similarly derivative of the grammars of the input language(s).
If a lexicon is provided, it seems that children can create a grammar anew, though apparently only in the presence of a sufficiently large community and only with continuous input from new cohorts who enhance the language-like nature of the communication system; the most striking evidence comes from deaf sign languages, while other possible sources of evidence might be creoles and twin languages, although especially in the case of creoles there are strongly competing hypotheses.
