Sexual system is often linked to diversification patterns across 18 phylogenetically diverse angiosperm families, whereas mating system does not better explain diversification than null models.
- Why it matters: This addresses why some parts of the tree of life are more species-rich by testing whether reproductive biology—especially self-fertilization—predicts diversification beyond single-family studies.
- What they did: The authors use state-dependent speciation-extinction (SSE) methods across 18 phylogenetically diverse angiosperm families, comparing models that incorporate mating system and sexual system, and considering hidden-state SSE advances.
- The result: Mating system does not better explain diversification than null models, while sexual system often does; family-level heterogeneity suggests broader trends may not hold across families.
