  We propose a third idea for the explanation of the leptonic flavor structure
in addition to the prominent approaches based on flavor symmetry and anarchy.
Typical flavor patterns can be modeled by using mass spectra obtained from the
discrete lengths spectrum of tight knots and links. We assume that a string
theory model exists in which this idea can be incorporated via the Majorana
mass structure of a type I seesaw model. It is shown by a scan over the
parameter space that such a model is able to provide an excellent fit to
current neutrino data and that it predicts a normal neutrino mass hierarchy as
well as a small mixing angle \theta_{13}. Startlingly, such scenarios could be
related to the dimensionality of space time via an anthropic argument.
