  We present a short review of a 6-dimensional model where a flavour puzzle of
the Standard Model fermions finds an elegant solution. The mechanism is based
on an idea that the three fermionic generations originate from a single 6D
family. The model explains in a natural way both charged fermions mass
hierarchy and small mixings in the quark sector, and tiny neutrino masses and
large neutrino mixings. We also discuss some phenomenological aspects of the
model which can distinguish this class of the models from another one and can
help to look for manifestations of new physics at colliders and other
experiments.
