  We have embedded the texture of the neutrino mass matrix with three families
into the MaVaNs scenario. We take the power-law potential of the acceleron
field and a typical texture of active neutrinos, which is derived by the D_4
symmetry and predicts the maximal mixing of the atmospheric neutrino and the
vanishing U_{e3}. The effect of couplings among the dark fermion and active
neutrinos are studied by putting the current cosmological data and the
terrestrial neutrino experimental data. It is found that the neutrino flavor
mixings evolve as well as the neutrino masses. Especially, U_{e3} develops into
the non-vanishing one and \theta_{atm} deviates from the maximal mixing due to
couplings among the dark fermion and active neutrinos.
