A new paper using analytical and simulation models to explore the relationships between particle-level heritability and collective-level heritability during major transitions has been published in BMC Biology:

From the Abstract:

Rather than being an impediment to major transitions, we show that, under a wide range of conditions, the heritability of collective-level traits is actually higher than that of the corresponding particle-level traits. High levels of collective-level trait heritability thus arise “for free,” with important implications not only for major transitions but for multilevel selection in general.
