It is argued that small values of the neutrino masses may be due to
anthropic selection effects. If this is the case, then
the combined mass of the three neutrino
species is expected to be ~1eV, neutrinos causing
a non-negligible suppression of galaxy formation.

The taboo of the ``A-word'' seem to be weakening in the
physics community, as you'll see if you click
to search for anthropic on arxiv.org. My last search gave as many as 128 hits, mostly recent work, providing a good
entry point into the literature.
Our paper above focuses merely on neutrino mass. I've previously written papers about anthropic constraints
CMB fluctuation amplitude
dimensionality of spacetime.
I reviewed the anthropic contraints (that I knew of at the time) on all physical and cosmological parameters in
section 4 of
this paper, and gave a brief but more accessible account
in my Scientific American article about parallel universes.
