Over the course of millions of years, the common rat that we know today has became a species quite different from what we’re used to. Over time, the rat evolved into Volanti Rattus, or a Flying Rat. Because of many factors collected by Charles Darwin involving the environment, population, survival and so on, the little pest we deal with today has grown wings and glides through tropical skies in its new habitat.
This rat’s new flying ability allows the rat to develop cartilage, connecting its limbs together like a parachute, to glide through the tropical trees in search for bird eggs. With the frequent rain showers on the island and the water surrounding the land, water resistant fur helps the rat grow immune to the abundance of water, if it

When the first 20 rats settled in the island, it was like a clean slate for the species. No obvious predators, and lots of obtainable food (vegetation). This sense of independence allowed the rats to reproduce with no boundaries, thus causing overpopulation. As the rat population skyrocketed, the variation in genetics became obvious. Morphological and behavioral traits began to change as mutations or different genetic alleles began to join; the rat’s body structure began to develop the ability to fly, and the rat’s diet became more plant-based because of lush plants and trees. Many of these variations helped the rat survive, but eventually competition rose within the island. In the early stages of the rat’s evolution, it tried to fish for food in the water, but a bird species was far too strong to compete with, so the rat began to float in the water when the birds weren’t around to attack. As variation and population grew, environmental pressures began to take its toll, and within the rat species, only the fittest could survive. The rats who didn’t develop the beneficial adaptations fast enough soon died. The best adapted rats became the primary animals, and the best began to reproduce. Reproduction allowed the traits of the fittest rat to be passed down to further generations, so those traits were locked in the rat’s evolution. After all of this is completed, the final component to the Ideas of Natural Selection occurs. The well adapted rats continue to reproduce, and then the species spreads out through the island, thus restarting the cycle and creating diverse new species, defined as speciation. This cycle is what turned the normal rat into an extraordinary species called the Flying

Graphic novels are something that requires a lot of deliberate thought and dedication to create a novel that affects the reader in the way authors want them to. Everything within a graphic novel is conscious decision to enable the tones, story, characters, and messages to get through as best as they can. Due to this it is difficult to create an adaption based on someone else’s work, as you want to portray their messages and tones accurately, but also how the creator interoperates the original authors work. This is a problem I had in the creation of my mini graphic adaption of The Flying Troutmans by Miriam Toews. The Flying Troutmans is about a family going on a trip in America in search of the father of the kids Hattie is in charge of after
In the book The Invention Of Wings there were many themes written all over it. Though I found that the theme in this book is, everyone should be treated the same no matter the color of your skin. For example, in the book all of Mr. and Mrs. Grimke slaves were treated horrible. Unlike Sarah, at a very young age wasn’t blind on how badly the slaves were being treated. Sarah didn’t believe in any human being treated the way they were being treated. Action speaks louder then words and Sarah definitely proved that when she was given Handful, as her own personal handmaiden slave. Sahara treated Handful as if she was colorless almost like if color didn’t exist in her eyes. Even though Sarah had to be very cautious because she was still living under
When the Atlantic Puffin’s young becomes mature enough to leave the nest, it will wait until night to emerge. Often its first time out of the nest, the young puffin becomes acclimated to its surroundings and begins to descend the perilous cliff face. Once it reaches the bottom, it will quickly travel out to sea. It leaves the island alone and will not return to land for two to three years.
In Mivart’s Genesis of Species, the author highlights the inconsistencies of Darwin’s natural selection theory. He supports his assertion by emphasizing how species placed in similar environments acquire different traits, questioning the long-term advantages of these evolved traits, and noting the logical inconsistencies of how traits can span in all directions.
The second of Tinbergen’s questions Phylogeny looks at the evolutionary explanations of development, as opposed to just how behaviour has adapted, including mutations in response to environmental changes. Some of these mutations remain in species even after necessity has gone, and can influence future characteristics of that species. The third of Tinbergen’s questions looks at Causation,...
Evolution in general, is a hard concept to grasp. There are multiple factors that effect the outcome a species, for example: genetics, nurture, nature, and the environment all play an important role. It was once said that species do not survive due to the fact that they are the strongest or the most intelligent, but because that species is the most responsive to change.
The Galapagos Islands, located about 600 miles west of continental Ecuador, contain a rich history of settlement and exploration and represent a living example of evolution that is still relevant today. For centuries, this chain of volcanic islands has been used uniquely by various cultures based off distinct needs. What has remained the same however is the fact that island isolation has forced many animal and plant species to adapt differently from one another based off their island’s environmental conditions, creating a living model of microevolution over time. Today, these models tend to be the primary resources used by biology professors when teaching their students evolutionary topics.
Charles Darwin’s theory of natural selection explains the general laws by which any given species transforms into other varieties and species. Darwin extends the application of his theory to the entire hierarchy of classification and states that all forms of life have descended from one incredibly remote ancestor. The process of natural selection entails the divergence of character of specific varieties and the subsequent classification of once-related living forms as distinct entities on one or many levels of classification. The process occurs as a species varies slightly over the course of numerous generations. Through inheritance, natural selection preserves each variation that proves advantageous to that species in its present circumstances of living, which include its interaction with closely related species in the “struggle for existence” (Darwin 62).
They evolved into 2 different species by many factors in nature. The factors include genetic drift, mutation, natural selection, and etc. Genetic drift involves the bottleneck effect and the founder effect. I hypothesize that a bottleneck effect took place in the island that the rodents were living in. A natural disaster must of happened and the rodents that had high fitness survived. Therefore since one population survived, that makes them two separate species. I also hypothesize that there was a founder effect in the population of the rodents. A small portion of rodents migrated to Nevis island and reproduced. When this happened this created a whole new population of rodents. Another reason that they could have been 2 different species can be due to gene flow. Some rodents could of migrated to Nevis island.
Charles Darwin has five parts to his theory of natural selection, firstly the “Geometric increase” which claims that “all living things reproduce in great numbers”, meaning that species may survive but not all will survive because, the resources used for survival for instance ,food will not be enough for all living things. “The struggle for existence” because there is a limited number of resources and can only sustain some and not all, not all living things will survive, however the question lies in which living being will survive?. “Variation” is the third part of natural selection which claims that within those living things there are variations within them that will determine whic...
The results of natural selection in Darwin 's finches and British Columbian sparrows change my view of species because every living animal changes to survive conditions that get in the way of normal life.
With the studies that Charles Darwin obtained he published his first work, “The Origin of Species.” In this book he explained how for millions of years animals, and plants have evolved to better help their existence. Darwin reasoned that these living things had gradually changed over time to help themselves. The changes that he found seemed to have been during the process of reproduction. The traits which would help them survive became a dominant trait, while the weaker traits became recessive. A good example of what Darwin was trying to explain is shown in giraffes. Long-necked giraffes could reach the food on the trees, while the short-necked giraffes couldn’t. Since long necks helped the giraffes eat, short-necked giraffes died off from hunger. Because of this long-necks became a dominant trait in giraffes. This is what Charles Darwin would later call natural selection.
According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.
Rats are undesirable creatures that have been the symbol of death, pestilence, and disease. Rats can cause billions of dollars in damage and can start fires, spread serious diseases, and multiply rapidly to infest homes, according to the article Top Ten Fascinating Facts About Rats. Additionally, the inundation of rats in a home can cause panic and mass hysteria, with residents calling pest control companies and law enforcement as soon as they see a rat, as expressed by John Davidson in Floods See Rat Population Explosion . The trouble that the rats cause has been an issue for a very long time. The flood of rats that invade a home is believed to be caused by an increases in food sources near populated areas, and decreases in predators and dry
