[R-sig-ME] Group selection and multi-level modeling

[Dominick Samperi]

The new E. O. Wilson book 'The Social Conquest of Earth" claims
that the long dismissed idea of group selection is gaining some
traction in part due to "multi-level modeling."

Can anyone point to work that aims to support this idea and
that employs the kind of models and software that is discussed
here on the SIG-ME list?

Thanks,
Dominick
