Present neutrino data are consistent with neutrino masses arising from a common seed at some 'neutrino unification' scale MX. Such a simple theoretical ansatz naturally leads to quasi-degenerate neutrinos that could lie in the electron-volt range with neutrino mass splittings induced by renormalization effects associated with supersymmetric thresholds. In such a scheme the leptonic analogue of the Cabibbo angle θ⊙ describing solar neutrino oscillations is nearly maximal. Its exact value is correlated with the smallness of θreactor. These features agree both with latest data on the solar neutrino spectra and with the reactor neutrino data. The two leading mass-eigenstate neutrinos present in \ne form a pseudo-Dirac neutrino, avoiding conflict with neutrinoless double beta decay.
