Holocentric chromosomes, lacking a centromeric region, ... Chromosomal rearrangements trigger speciation by acting as barriers to gene flow. However, the underlying theory was developed with monocentric chromosomes in mind. Holocentric chromosomes, lacking a centromeric region, have repeatedly evolved and account for a significant fraction of extant biodiversity. Because chromosomal rearrangements may be more likely retained in holocentric species, holocentricity could provide a twist to chromosomal speciation. Here, we discuss how the abundance of chromosome-scale genomes, combined with novel analytical tools, offer the opportunity to assess the impacts of chromosomal rearrangements on rates of speciation by outlining a phylogenetic framework that aligns with the two major lines of chromosomal speciation theory. We further highlight how holocentric species could help to test for causal roles of chromosomal rearrangements in speciation. |
