Why have some plant species changed pollinators in their evolution? An international team of researchers from the Universities of Bonn and Xi’an Jiaotong-Liverpool University Suzhou (China) studied the reproductive systems of three sister species pairs, where one species is pollinated by insects and the other by hummingbirds. Mechanisms were discovered that explain the switch from insect to bird pollination. The study has now appeared in the journal Ecology and Evolution.
