Justification
Long Hair
The place where the animals where moved is a lot more cooler so having shorter hair would not keep them warm, especially in the winter months the temperature might drop even lower.
Brown Eyes
Brown eyes is normally the most dominant allele when it comes to eye color especially if are an offspring of a parent who carries both of that gene.
Short Tails
The animals that are horse-like animals most likely whisk their tail to shoo away flies that tend live in warmer temperatures.
Long Necks
The only food that the animals are abled to eat are a tree. It turn red when rip, but who knows how long it would take for the for the fruit to actually for on the floor to be eaten. Longer necks would get them to the food more easily.

The only sound that would be heard is the wind and other animals of the same species.
Slow Runner
The island that the animals were moved on is only few square kilometers long so it not very big in size. They need to run won’t be necessary because they are surrounded more by water then they are by land, and getting to one section to another would take few time
No Color Vision
Everything on the island is basically the same and there is no constant change from day to day such as food. There only one type of food to eat and it grows on the tree. Once the animals become accustomed to it and that all there ever going to it, without seeing it but instead smelling it they would know what it is.
Short Noses
If the neck does become longer from natural selection then the nose would not be so long because their sense of smell would be great.
Long Tongue
Everything that they eat is on the tree so certain fruit might be much higher then other so if there neck is long enough to reach the other fruit they an use their tongue to get it.

Natural selection is basically keeping the more desired traits while, slowing dying off the ones that are not need. So say for example the animals that are from the mainland their hair are short due to extreme climate. The animal on the island that has much cooler temperatures, the hair would be longer.
The environmental factors that influence the allele selection was the food being on the tree, the cooler climate, the amount of space provided, and there being no natural enemies.
Adaption is when you learn to accommodated your needs with surrounding that are unfamiliar to you. For example if you were use to picking fruit off of a bush but now its higher in the tree, you would have to find a way to get the fruit off the tree because there not fruit low enough for you to eat. The adaption the animals would learn with being on the island would be getting the food out the tree, having to learn to become more warmer since the temperature are
alligators and other edible animals. They would also split up into smaller bands to gather plants
this is due to the habitat they live in and the small number of people living
owners feed them only fruits - and they need many other nutrients for a balanced, healthy
People sometimes wonder how organisms get so different from their ancestors. The answer is through their genes. Organisms over generations are always adapting to the environment. They are becoming better fit for survival to reproduce and live. The rock pocket mice were tested under different gene traits and environmental conditions to see what rock pocket mice would survive and reproduce more offspring. The different environments the mice were measured under are the ice age or desert and the different alleles that were tested were color, thickness of fur, and strength of jaw. Brown is dominant to white, normal fur is dominant to thick, and normal strength is dominant to strong. Of course through
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.
Natural selection is a key part of nature and determines which animals thrive. Natural selection is the process by which organisms better adapted to their environment tend to survive just and produce more offspring. Some examples of animals who adapted to their environment by natural selection are finches and tortoises. In 1831,Charles Darwin set off on a five year voyage. After looking along the coasts of South America, the ship stopped at Galapagos Islands. During his stay on the islands, he observed the finches and tortoises on each island. He noticed that the finches and tort...
Despite the lost coral islets and atolls, the islands have extremely fertile soil. However, certain conditions do affect development. The islands are small with fixed boundaries and are occupied by tens of thousands of people. Irrigation is not possible, limiting their agricultural capabilities to dryland field systems. Being in the middle of the ocean leaves them susceptible to natural disasters such as cyclones and droughts (Kirch 1984: 221).
They came off in the poor nature all going completely naked even for the woman of the island, except for one girl. All of which in the population of the island were young none over the age of thirty. Describing them in a fine matter with fine body shapes and faces, and long think hair pulled to the back. Many of which would paint their body’s and faces in a variety of colors. For as the men of the island were all of good size and stature, and all being handsomely formed. Indeed some had scars and wounds over their bodies from protecting themselves. Despite that they stated they received them from surrounding island that tired making prisoners of them, the admiral firmly believes they are from the continent. The fact that they portray to be ingenious people they showed not being acquainted to weapons in any form. Having nothing more than sticks with fish bones being truly amazed by the sight of the swords, cutting themselves out of ignorance. As well as not appearing to have any form of religion, they were very quick learners on picking up words spoken to them. They became such a liking to the admiral he wanted to take back a hand full of them to be servants. In spite of their being an immense population of people there was no sight of animals other than parrots on the
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.
What would life be like landing on an tropical island? In the book Swiss Family Robinson, the Robinsons, who learned to live self-reliantly on an uninhabited island, tame many unruly animals. They tame an eagle and a donkey, because the animals had to adjust to the family’s needs.
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.
The term was first introduced by Charles Darwin in the 1859 book On the Origin of Species. Selection is process by which heritable traits that make it more likely for an organism to survive and successfully reproduce become more common in a population over successive generations. Like in Darwin book, Galapagos finches all have different types of beaks. During drought, the finches with the larger beaks survived better than those with smaller beaks. During rainy times, more small seeds were produced and the finches with smaller beaks fared better.
Many scientists in the past, such as Aristotle and Plato, believed that there were no changes in populations; however, other scientists, such as Darwin and Wallace, arose and argued that species inherit heritable traits from common ancestors and environmental forces drives out certain heritable traits that makes the species better suited to survive or be more “fit” for that environment. Therefore, species do change over a period of time and they were able to support their theory by showing that evolution does occur. There were four basic mechanisms of evolution in their theory: mutation, migration, genetic drift, and natural selection. Natural selection is the gradual process by which heritable traits that makes it more likely for an organism to survive and successfully reproduce increases, whereas there is a decline in those who do have those beneficial heritable traits (Natural Selection). For example, there is a decrease in rain which causes a drought in the finches’ environment. The seeds in the finches’ environment would not be soft enough for the smaller and weaker beak finches to break; therefore, they cannot compete with the larger and stronger beak finches for food. The larger and stronger beak finches has a heritable trait that helps them survive and reproduce better than others for that particular environment which makes them categorized under natural selection (Freeman, 2002).
