The origin of the angiosperms (flowering plants) has long been debated. Even with the advent of molecular techniques for phylogenetic analysis, the question has been thought intractable because of the significant evolutionary distance between the angiosperms and their closest relatives in the plant kingdom. Mathews and Donoghue (p. 947) attacked the problem by analyzing duplicate phytochrome genes. They root the family tree of the angiosperms among the water-lilies and two primitive Australasian plant genera, Amborella and Austrobaileya.
