Abstract
A plant population from an interspecific cotton hybrid produces flowers with exposed ovules on petal margins. The variability of these abnormal flowers suggests the possibility that angiosperms may have evolved by accumulating regulator genes which narrow the range of response to fluctuations in the environment. Progressive canalization of development within a population like the "carpelloid petal" plants could have resulted in both angiospermy and speciation.Keywords
