Natural Selection … WebNatural selection favors gene variants that help the devils survive the disease and reproduce. Those favorable gene variants might underlie shifts in life history strategies (as recent research hints at), in behavior, or in how the devils’ immune systems fight the cancer. Evolution may yet stumble upon a solution for the devils.
