Despite the many questions regarding satellite DNA sequences and their cellular roles, the evolutionary history of eukaryotic genomes seems to have been largely influenced by this dynamic and multifaceted genomic component. The bovine genome is highly rich in diverse satDNA sequences that differ in monomer sequence and length, complexity, chromosomal location and abundance, as well as in their sequences’ evolutionary mechanisms. In the evolution of the Bovidae family, the genomes’ repetitive fraction played a central role in karyotype reorganisation, and in the last few decades several studies have demonstrated and reinforced an association between centromeric satDNAs and the process of chromosome evolution in remodelling genomes of Bovidae species. Here, we review different aspects of the molecular nature and genome behaviour of all the satDNA families identified in the bovine genome, including their organisation, abundance, chromosome localisation, variation in sequence, and evolutionary history in the Bovidae family and in particular in the Bovinae subfamily, taking an integrative perspective. “Evolution and satDNA” can be addressed through two complementary views: the satDNA sequence evolution per se, and genome evolution promoted by the satDNA dynamism. SatDNA both provides phylogenetic information and is a critical genomic component that enables sequence and chromosome evolution–features arising from its presence, absence or alteration.
