Abstract: We investigate a variant of evolution-communication P systems where the computation is performed in two substeps. First, all possible an- tiport rules are applied in a non-deterministic, maximally parallel way, moving evolution rules across membranes. In the second substep, evolution rules are applied to suitable objects in a maximally parallel way, too. Thus, objects can be the subject of change, but are never moved themselves. As result of a halt- ing computation, we consider the multiset of objects present in a designated output membrane. When using catalytic evolution rules, we already obtain universal computational power with only one catalyst and one membrane. For systems without catalysts we obtain a characterization of the Parikh images of ET0L languages.
