Resumen
Leaf venation architecture varies greatly among living and fossil plants.
However, we still have a limited understanding of when, why and in which
clades new architectures arose and how they impacted leaf functioning.
Using data from 1,000 extant and extinct (fossil) plants, we reconstructed
approximately 400 million years of venation evolution across clades and
vein sizes. Overall, venation networks evolved from having fewer veins
and less smooth loops to having more veins and smoother loops, but these
changes only occurred in small and medium vein sizes. The diversity of
architectural designs increased biphasically, first peaking in the Paleozoic,
then decreasing during the Cretaceous, then increasing again in the
Cenozoic, when recent angiosperm lineages initiated a second and ongoing
phase of diversification. Vein evolution was not associated with temperature
and CO2 fluctuations but was associated with insect diversification. Our
results highlight the complexity of the evolutionary trajectory and potential
drivers of venation network architecture.
