Other claims from this paper (17)
- Observation Primary fire-adapted diversification contributed 20% of speciation events over 120 million years.
- Observation Secondary diversification accounted for 30% of fire-adapted trait assignments.
- Observation Stabilisation accounted for 50% of fire-adapted trait assignments.
- Observation All four fire-response types trace back more than 100 million years.
- Observation Resprouting was not consistently ancestral to seed storage or non-sprouting.
- Observation Fire-adapted traits evolved slowly in the Cretaceous and rapidly but intermittently in the Cenozoic.
- Observation Resprouter speciation peaked in the past five million years.
- Observation All four fire-response trait types had a trough 40–30 million years ago.
- Observation Thick bark and serotiny originated among extant Pinaceae in the Mid-Cretaceous.
- Observation Heat-stimulated hard-seed germination was ancestral in Fabales.
- Observation Smoke-stimulated non-hard-seed germination was older and included Restionaceae-Anarthriaceae.
- Observation Some fire-free lineages retain smoke or karrikin responses consistent with fire-prone ancestry.
- Observation In fire-prone clades, absence of fire-related traits was inferred to be advanced.
- Association Fire-prone clades lost serotiny and soil storage with increasing fire frequency.
- Association Migration to fire-free habitats was associated with loss of thick bark, flowering, serotiny or soil storage.
- Observation Protea and Hakea showed repeated interchange between resprouting and non-sprouting states.
- Recommendation Authors recommend incorporating fire-proneness and fire-related traits into studies of plant evolution.
