2. Pocket Mice or the Rock pocket Mice is among the 19 species of the pocket maice found in the rocky outcrops in the deserts of the Southwestern United States and mexico. The Mice is about 12-18 gms in weight, 18 cms in lenght and is nocturnal in habitat (in the day time they shield themselves from the desert heat). They come out at night to find plant seeds-their only source for food and water, and live in the underground burrows , to find refuge from the Owls, their main predator, They have been subdivided into ten sub-species based on their geographical distribution and their coat colour. Most of them have light, tawny fur which blends well with the desert soil/rock, where they live. However, we also get to see the dark colored mice population in the black basaltic rock formation. The scientists sampled DNA from both the drk and the light colored mice from the areeas of Pinacete peaks, Mexico and New Mexico. In the Pinacete mice they observed a consistent connection between the different version of the Melanocortin-1-receptor gene and the coat color. Studies shoeed that there is strong selective pressure maintaining Mc1r allele and coat color frequencies across the short geographic distance between the light and dark colord rock island. thus Melanism in the pocket mice is an example of adaptation by natural selection. Changes in the Mc1r gene sequences are not responsible for the colour differences. this led the resewrchers to conclude that the most identical dark coat colors developed many time in the pocket mice is an example of CONVERGENT EVOLUTION. 3. The evolution of peppered moth is an evolutionary instance of color variation in the moth population as a rsult of Industrial revolution. In pre industrial England, most of the peppered moths had mottled grey wing, camouflaging with the Birch trees where they rested. Coal soot from the industries gradually made the tree trunks black in the urban areas and left the moths vulnerable to the predators.In a short time dark variants of the moths sprang up.The dark colored were better camouflaged than their lighter counterparts and hence they proliferated and survived.Gradually, Black became the norm for the urban moths.As the cities, reduced pollution so did the tree trunks lighten up and gradually the moths too got light.A classic example of SURVIVAL OF THE FITTEST. So, off now, if I were to be a moth , I would be a lighter one. Solution 2.
