Read the following information and answer the given questions. Thousands of years ago only one species of squirrels was there and were evolvedfrom common ancestor. At present there are two species of squirrels, though they have similarities amongthem, cannot perform reproduction between them.a) Analyze the factor responsible for this change.b) How can this kind of changes be considered as beneficial for species?

The central argument of Darwin’s theory of evolution starts with the existence of hereditary variation. Experience with animal and plant breeding had demonstrated to Darwin that variations can be developed that are “useful to man.” So, he reasoned, variations must occur in nature that are favourable or useful in some way to the organism itself in the struggle for existence. Favourable variations are ones that increase chances for survival and procreation. Those advantageous variations are preserved and multiplied from generation to generation at the expense of less-advantageous ones. This is the process known as natural selection. The outcome of the process is an organism that is well adapted to its environment, and evolution often occurs as a consequence.

This origin of species from a common ancestor occurred by evolutionary processes. This is made clear by an exhibit on the Ark Encounter where we learn that, “species give rise to new species, modified characteristics develop over time, and the fittest animals survive.” This is a reasonable description of Darwin’s explanation for the origin of species by means of natural selection. Many visitors to the Ark Encounter may be surprised to discover exhibits which embrace Darwin’s mechanism—natural selection—for producing new species albeit with some strict limits. Along with other natural mechanisms of change the Ark Encounter has proposed what I call a “post-flood rapid speciation model” of modern biological diversity to solve the problem of the limited dimensions and manpower of Noah’s Ark.
