Bryozoan zooidmodules interact with other units and are integrated both within themselves and in an inclusive whole. They originate from budding loci and differentiate as populations of cells. However, they are also inclusive of another level of modularity, in that organs differentiate as entities or parts of the zooids. Both levels of modularity can be individuated using key criteria of evolutionary developmental biology. Read more about Evolution and ecology in modular organisms
