ANT 100 Study Guide - Quiz Guide: Directional Selection
Document Summary
Referring to the ember, et al. textbook, chapter 3, explain how directional selection in the speckled moth occurred in england in the 1800s. In the case of the speckled moth, directional selection occurs when a specific-colored moth develops its own color to benefit the environment in which it is put. For example, the white-colored moths, which are born in the light forest alongside the black-colored moths, have been connected with predator risks. In this case, white-colored moths blended or engaged in the phenomena of camouflaging, where its characteristic, which is its color, provides its own benefit for predators not to notice it directly. This occurrence, which is caused by the suitable color-matching with moths and the environment, is a directional selection in which these species survive and reproduce more than those with black moths. White-colored moths are preferred over black-colored moths in this situation due to the bright forest-type setting.
