  MOdified Newtonian Dynamics (MOND) is an alternative to the standard Cold
Dark Matter (CDM) paradigm which proposes an alteration of Newton's laws of
motion at low accelerations, characterized by a universal acceleration scale
a_0. It attempts to explain observations of galactic rotation curves and
predicts a specific scaling relation of the baryonic and total acceleration in
galaxies, referred to as the Rotational Acceleration Relation (RAR), which can
be equivalently formulated as a Mass Discrepancy Acceleration Relation (MDAR).
The appearance of these relations in observational data such as SPARC has lead
to investigations into the existence of similar relations in cosmological
simulations using the standard {\Lambda}CDM model. Here, we report the
existence of an RAR and MDAR similar to that predicted by MOND in {\Lambda}CDM
using a large sample of galaxies extracted from a cosmological, hydrodynamical
simulation (Magneticum). Furthermore, by using galaxies in Magneticum at
different redshifts, a prediction for the evolution of the inferred
acceleration parameter a_0 with cosmic time is derived by fitting a MOND force
law to these galaxies. In Magneticum, the best fit for a_0 is found to increase
by a factor of approximately 3 from redshift z = 0 to z = 2. This offers a
powerful test from cosmological simulations to distinguish between MOND and
{\Lambda}CDM observationally.
