In this paper we review some recent results on the evolution of probability measures under cellular automata acting on a fullshift. In particular we discuss the crucial role of the attractiveness of maximal measures. We enlarge the context of the results of a previous study of topological Markov chains that are Abelian groups; the shift map is an automorphism of this group. This is carried out by studying the dynamics of Markov measures by a particular additive cellular automata.
Many of these topics were within the focus of Francisco Varela's mathematical interests.

Key terms: Topological Markov chains, cellular automata, maximal measure, entropy, additive cellular automata.
