Hybrid crosses could provide a means of driving adaptive evolution

Individual point mutations in DNA provide a mechanism by which organisms evolve altered proteins that can prove to be advantageous. However, this explanation for the successful adaptation of an organism to a novel environment is problematic, as colonization of specific niches should require multiple gene interactions that are unlikely to occur by single sequential genetic alterations. In the August 7
Rieseberg et al. investigated three species of
