CONSERVATION OF WILDLIFE Rock salt is used to clear snow from roads, this would bring up evolutionary changes in the Monarch butterfly. When snow melts, road salt runs into nearby soil and into the roots of common plants, which are in turn ingested by caterpillars. Then, as they become adult butterflies, their brains and muscles develop abnormally. male Monarch butterfly develop thoracic muscles,larger muscles helps male fly longer and farther,. enabling them to find more mates. Females monarch butterfly develop larger eyes and brain (salt contains sodium which helps in brain development), larger eyes of female helps to seek better plants on which to lay their eggs. In this way human are contributing to progressive evolution in Monarch butterfly. But there are adverse effects occurring through this process i.e Cabbage white butterfly could not resist change in the sodium levels so, leads to death, ultimately leading to extinction of species.
