Eva Jablonka, sua safadeeeeenha! :D (y) Two alternative hypotheses addressing the function of cytosine methylation in invertebrates are evaluated: (1) cytosine methylation is an ancient regulatory mechanism which was lost in species with low rates of cell turnover, and (2) cytosine methylation is primarily a defense echanism against genomic parasites and is expected to be present in all species with large genomes. The data [...] show no correlation between the percentage of DNA methylation and genome size within and between groups. Therefore, the strong version of the defense hypothesis, claiming that the role of DNA methylation in nonvertebrates is limited to genome defense, is refuted.
