We classify those subvarieties of X which contain a Zariski-dense set of CM points. This is an analogue of the André-Oort conjecture. As an application, we construct non-trivial families of higher Heegner points on modular elliptic curves over global function fields.LaTeX, 27 pagesNumber TheoryAlgebraic Geometry11G09; 14G35text
