In this paper, we implement a test of the standard law for the dark matter density evolution as a function of redshift. For this purpose, only a flat universe and the validity of the FRW metric are assumed. A deformed dark matter density evolution law is considered, given by , and constraints on
are obtained by combining the galaxy cluster gas mass fractions with cosmic chronometers measurements. We find that
within 2
c.l., in full agreement with other recent analyses.
