If you look at the permalink variable in your Template you can see exactly what Template Group and Template it’s using.  By default, the variable is {permalink="weblog/index"} which means it’s pointing to the “index” Template of the “weblog” Template Group.

If you wish the permalinks to point somewhere else, then you simply need to alter the variable.  For instance, if you wanted the links to point to the “world” Template in the “news” Template Group you could use {permalink="news/world"}.
