A widely held hypothesis in evolution is that adaptive specialization constrains the potential direction of future evolutionary change and thus may be irreversible, also known as Dollo's law. However, this hypothesis ...
Cyrtandra(Gesneriaceae)is a genus of flowering plants with over 800 species distributed throughout Southeast Asia and the Pacific Islands.On the Hawaiian Islands,60 named species and over 89 putative hybrids exist,mos...
Work started while the first author was working at PE and would like to take this opportunity to thank Dr. Yin Zheng Wang for guidance. We are grateful to Professor James Smith for his constructive comments and language improvements on the manuscript, and to Dr. Fang Wen for kindly providing dried leaves of some species analyzed in this study. We would like to thank the institutions (PE, HITBC, and HEAC) that provided pollen for this study.
