The research confirms that natural selection the process in nature where organisms genetically adapt to their surroundings is a powerful influence in the canyon.
"It is nice to see the molecular work finally completed, and that the molecular signal confirms the phenotypic data: There is divergence between the two slopes," said Marta L. Wayne, a professor of biology at the University of Florida and a member of the UF Genetics Institute, who was not involved in the research. "This is interesting because the slopes are close enough that we know animals travel between them, yet selection is so strong that there are differences between animals on the two slopes. This is really strong natural selection."
