Multichimera

The formation of Botryllus multichimeras sets the 'group level' (the assemblage of several genotypes into one unified entity) as the key level at which natural selection acts.

Around the time of the events that led to your birth, there was no longer anything new even about multichimeras.

However, it was suggested that potentially losing genotypes (defined as such in bi-chimeras scenario) might survive in multichimera entities as stem cells in refugia and successfully propagate to succeeding generations.

The multichimera state is shown to have a power law distribution of synchronized cluster sizes, whose exponent is found to be independent of the system parameters..
