Enhanced: Sex, Sunflowers, and Speciation
Richard J. Abbott
Matings between different species (interspecific hybridization) provide increased genetic variation and new gene combinations that could be a potent force in adaptive evolution and the production of new species. As Abbott explains in his Perspective, evidence for this has so far been scant, but is now provided by new work on interspecific hybridization in sunflowers (Rieseberg et al.).
