Such can be seen in the example of industrial melanism where the colour of the moths changes according to their surroundings. ![]() The selection of the fittest is the way one organism leads to its evolution to a better adaptable species. A typical rock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. Rock pocket mice, Chaeotdipus intermedius, are an ideal. So, the answer is option A, ‘the mice with the black fur mutation would unlikely survive and would disappear over time’. The sequence you get sequence ofa identicae pocket mouse population with dark-colored that ofthe same gene fur that lives on Jnother rock following different. Abstract: Elucidating the causes of population divergence is a central goal of evolutionary biology. According to the theory, only the fittest of the varied species would survive and the brown fur mice were the fittest as they were able to camouflage from their predators and the black fur mice developed desirable mutation which needed to be passed on to the next generation. This led to the natural selection of the brown fur mice as they were well suited and adapted to the surroundings. On the other hand, dark-colored rock pocket mouse populations have been found living on black, basaltic rock formations caused by geologic lava flows. This led to the decrease in the population of the black fur mice to a level where no black fur mice were spotted later on. Most rock pocket mouse populations have sandy-colored fur, which is consistent with the light color of the desert rocks and sand on which they live. Hence making them easy prey of the predators. But the black fur mice were visible to the predators due to their dark fur colour which wasn’t able to camouflage on the scrub surfaces. Rock pocket mice inhabit desert and are particularly associated with rocky areas. The Rock Pocket Mouse is nocturnal and terrestrial, and it is probably active throughout the year in the southern part ofits distribution, although it is. The mice with brown fur cover easily camouflaged themselves on the scrub making them not visible to the predators. The mutations caused in the rock pocket mice, was of the fur colour changing from brown to black. ![]() Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. Hint: According to the theory of natural selection, it was mentioned that the organism which is fitter and adapts fully to its new surroundings and passes on the necessary genes to its next-generation would only survive and the rest species would get destroyed. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock.
