Genome Architecture and Speciation in Plants and Animals.

ABSTRACT: There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms. First, we briefly summarise what is known about speciation in these groups; importantly, the diversification rate of plants is about twice that of animals, and species barriers in plants may arise at an earlier stage of divergence. Next, we discuss several of the major differences in how plant and animal genomes evolve, and how they may impact the evolution of reproductive barriers and potentially speciation rates. Key differences include (1) a higher frequency
