  • Determining the number of evolutions of an adaptive novelty is primordial to understand its evolutionary significance. C(4) photosynthesis, an adaptation to low CO(2) atmospheric concentration and high temperature, evolved multiple times, but the number of convergent evolutions is still debated. In Poaceae phylogeny, numerous C(4) groups are separated by C(3) taxa, but whether these correspond to independent C(4) origins or a few C(4) evolutions followed by reversals is controversial.
