DIRECTIONAL SELECTION
A Lesson of Butterflies
Monarch butterflies are an example of directional selection. They have developed a trait that birds find foul-tasting. Birds are predators (known as
Directional selection has shaped the oral jaws of Lake Malawi
Taken together, our results imply that the rapid and replicative nature of cichlid trophic evolution is the result of directional selection on chromosomal
natural selection: stabilizing
Stabilizing selection favors the norm, the common, average traits in a population. Look at the Siberian Husky, a dog bred for working in the snow.
