Allopatric speciation, Natural Selection: Reproductive selection, and Natural Selection: Diversifying selection.

How the Nevus and St. Kitts Rodents became different is a thrilling elaborate tale that few know, and even less understand. It all began on the fateful day of the only category 6 hurricane ever recorded..

..As Huth raged on it was clear that nothing could survive her powerful winds, torrential downpours, and bursts of lightning. The story of our rodents begins in the deep hull of the super ship, Mary Anne. This old but stubborn ship has gained its name as not only one of the oldest ships in use, but also as the most resilient to the environmental escapades of our world. As the waves crash against the hull of good ol’ Mary Anne it becomes clear that this storm is not just a storm. It possessed the supernatural power of the Great Magic Sky Fairy, a power when released has the capability of destroying all life in its wake..

As the ships sways the rodents living aboard begin to stir. All of a sudden Mary Anne flips caught in a powerful crosswind. The rats are launched overboard. Those with strong legs from climbing containers within the ship immediately swim for the coast of what would one day become St. Kitts, their powerful legs help them swim a short distance against a strong current, while the weaker rodents slowly drift southeast towards the shores of Nevus, these rodents barely make it to the shore of Nevus, but by daybreak they do..

As these now separate rodents discover their environments it becomes apparent that by pure chance the rodents have had one stroke of divine luck. The rodents of St. Kitts with strong legs have to climb and jump for their food, which is over a meter above the ground, while the rodents of Nevus scavenge among the ground level foliage finding nuts and fruit.

The rodents of St. Kitts have to face a threat greater than that of the Nevus rodents. Constantly fleeing from the great Chupacabra the rodents must be able to move fast, jump high, be larger as to cover more distance, and reproduce quickly in order to continue in existence, while the rats of Nevus need only find enough food and lay comfortably in the sun.

Over hundreds of years this resulted in the natural selection of more desirable traits in each population, as needed by their environment, and because there was no natural way for the rodents to meet and procreate they continued to diversify. The rodents of St. Kitts began to grow longer legs so they could jump to their food and safety, while the rodents of Nevus grew to be slow and lackluster. As females and males of each population began to see what was best for their offspring’s survival the rodents of St. Kitts began to favor the height of the males jump, and the speed in which the females ran. The faster you could run, and higher you could jump the more reproduction you would participate in. However, at Nevus, females and males mated when they saw how much food a male could digest in one sitting, thus a brand of rats focused on leisure was born.

As the rodents of St. Kitts began to be targeted not only by the elusive Chupacabra but also by a wild and persistent poaching ring, they began to rapidly decrease in population. Scientists believing that the Nevus and St. Kitts rodents were the same attempted to bring rodents from Nevus to boost the population of St.Kitts, yet they found that not only were the rodents incapable of reproducing with the St. Kitts rodents, due to their lacking physical ability, and the high standards of the potential mates at St. Kitts, but were also incapable of foraging for food above them. This making it not only impossible to reproduce with the new species of rodent, mendacium sciuridae(lying squirrel) and sultus sciuridae(jumping squirrel), but also impossible to survive in their environment.
