| Method |
(Primary source): Researchers inferred a large phylogenetic tree for the grass family and estimated, through Bayesian molecular dating, the ages of the 17 to 18 independent grass C4 lineages. The first transition from C3 to C4 photosynthesis occurred in the Chloridoideae subfamily, 32.0-25.0 Mya. |
| Comments |
The C4 pathway independently appeared at least 50 times during angiosperm evolution [refs 6,7 in Reference]. |
