RSPB: Scott Hodges & Harvard Associates Study of Flower Petals Shows Evolution at the Cellular Level

November 17, 2011

A new study of flower petals shows evolution in action, and contradicts more that 60 years of scientific thought. The findings are reported by Scott A. Hodges, professor in the Department of Ecology, Evolution, and Marine Biology at UCSB, and a research team from Harvard University. Columbine flowers, known as Aquilegia, evolved several lengths of petal spurs that match the tongue lengths of their pollinators. The research team discovered that longer spurs result from the lengthening of cells in one direction, called anisotropy, and not from an increased number of cells. READ MORE (UCSB Featured News)
