The Influence and Effect Natural Selection Has On Rabbits Introduction Years ago Charles Darwin created the theory of natural selection. He attempted to explain how evolution worked, and his theory is now regarded as correct. Natural selection states that animals with traits that are better suited to their environment will survive and reproduce more. This would explain how evolution works. Groups of animals with the most beneficial traits survive and are able to reproduce. While the other group has difficulty surviving and would therefore reproduce less. The variation between that type of animal would come from a random mutation which turned out to be useful. An animal may get a mutation which is either beneficial or disadvantageous to the organism (1). As time progresses there are a larger amount of animals with the beneficial trait, while there is a lot less animals with the older trait. Natural selection correlates to the phrase “survival of the fittest” meaning that animals with beneficial traits will survive, while those without will die (2). Theoretically, this could lead to an entire change of the population; leaving only the group that can survive easily and produce more offspring. The purpose of the lab executed was to see what would happen to the traits of rabbits over generations as alleles in the new rabbits change. In the lab there were two types of rabbits--furred rabbits and naked rabbits. Having fur was the dominant trait and no fur was the recessive
Natural selection is the process in which heritable traits that make it more likely for organisms to survive and successfully reproduce become more common in a population over successive generations. Each of us individuals is specifically shaped and formed by our own genetic pattern. We inherit this pattern half from are mother and half from are father. The cause of this is the proximate cause that led it’s phenotype to ultimate causes. Much of we know today about evolution derives from the late great pioneer, Charles Darwin. Charles Darwin was an english naturalist that even from an early age was very interested in outdoor pursuits. Early in his prep career his father tried sending him to the University of Edinburg to pursue his medical
Natural selection involves the adaptation of a species to better survive in their designated environment. When organisms reproduce, they pass down their DNA to their offspring. For example, a child that is tall is the result of their parent being tall as well. Parents pass down traits to their children. When it comes to survival, some organisms are better at it than others based on the traits that they have acquired. Some organisms can camouflage from predators while members of the same species do not obtain that same trait. With that in mind, the ones that can camouflage will most likely survive in certain environments and they will then pass on that trait when they reproduce. Since these traits are advantageous, they are passed on to more and more offspring through time and it will eventually overcome any original traits that species first started out with. It’s kind of like the current state of sexual misconduct in Hollywood. We have our directors, actors, agents, and so forth. However, as time goes on, some do not survive in the business based on their inherently evil traits and they get weeded out just like some species in the wild. As generations pass, these organisms have then adapted to fit the environment and better survive based on their inherited traits.
1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic variation. Natural selection is basically the understanding that the environment can not support unlimited population growth, and not all organisms are able to reproduce to their full potential due to trait variation. For example, a black fly may
Natural selection is the process by which organisms better adapted to their environment survive and produce more offspring. It’s believed to be the main process that brings about evolution. Natural selection will over time remove the deleterious gene as they have a negative effect for the population and are therefore not going to survive or produce offspring.
Evolutionary biology has always interested me, specifically the mechanisms of natural selection and how species adapt to their environment. It started with my love for animals and nature when I was little. I spent my summers working with horses at a local corral, where I would ride around the surrounding wilderness areas. My favorite part about riding in the mountains was watching the change in plant and animal species as the elevation changed. It never ceased to amaze me how the alpine tree line was always so sudden. Humongous pine trees would give way to the short, shrubby plants of the alpine tundra so uniformly and noticeably. I have always wondered about the environmental conditions that cause species to distribute themselves in
The descendants of the species have been given changes from their ancestors. This is called natural selection. Natural selection is a type of evolution that animals go through when there is a hardship in their natural habitat. Most animals go through natural selection to survive, they can pass it on to their kin.
Evolution is the process of biological change by which descendants come to differ from their ancestors. Natural Selection is when an individual with the best trait survive and breed in more population. Larger populations of organisms with the desired traits will then occur and organisms will evolve. The four principles of Natural Selection are variation, over production, adaptation, and descent with modification. Charles Darwin, an English naturalist and geologist saw two major trends within organisms which were variation and adaptation. Variations are differences in individuals’ physical traits compared to other individuals. In the Galapagos Islands Darwin noticed that finches had different beak sizes and shapes. Darwin then concluded that finches with thicker beaks lived in areas where nuts were the main food source and finches with smaller beaks tended to live in areas where insects were the main food source. Adaptation are features that allow an organism to better survive in their environment. There has been many adaptations in animals but one of the best has been living in groups because animals can then “help each other find food, defend against predators and care for their young” (animalpanet, n.d.). Overproduction is when organisms produce more offspring than the environment can support. Darwin stated that all animals over produce since offspring can reach reproduction age and have offspring of their own. For example, “even a slow breeder
In lab 2 we are using computer simulations to investigate the four forces of evolution. The four forces of evolution include mutation, gene flow, genetic drift and natural selection. Mutation is a way for new alleles to be introduced into the population and is completely random. Gene flow is when a group of individuals migrate into a new population and bring with them new alleles like mutation this can also be random. Genetic drift is when alleles are taken out of a population because of some random occurrence unrelated to the alleles like a natural disaster etc.
Natural selection means the animals who have weaker genetic performance than its own kind will be deselected by the nature. This allows the species to evolve and advance its breed to remain their domination in the natural society. Charles Darwin adopted this idea to explain how the species that survived for ages are the superiors ones with the most substantial genes embedded in them. However, as mankind advanced from our ancestors till now homo-sapiens, knowledge people, natural selection reoccurs among humans in the late 19th century and early 20th century. Social Darwinism was created for the purpose to make changes in the world. In the late 19th century, Social Darwinism influenced the society and created immense impacts among the
The Dutch rabbit, is a sweet, fun-loving breed of rabbit. Always ready to explore what's ahead of them. Very social and friendly around people. Good for children as young as eight years old. I know from experience, having adopted one myself. Dutch rabbits are indeed, fun-loving, good with the younger kids and warm up to new owners quite well after a while.
A land that was once only animals has changed over time and became more human than anything. Taking a toll on the animals that were once there making them distinct. The old way was more animal and plants than people. Now things have switched versus back then as stated from the film they were native people there first which catered to the natural lining of the earth and animals. Now it seems as if they are adapting to our new ways including nature. " There are so many grammatical errors here that it makes no sense at
Humans have manipulated the natural selection process for many years to preserve favorable traits in their pets, crops and livestock. Long before Darwin, farmers were manipulating heritable traits of their plants and animals. For example, kale, broccoli, cabbage and cauliflower are just cultivated forms of wild mustard through artificial selection of certain attributes. When compared and contrasted, natural selection aims for fitness to survival whereas artificially selected traits are based solely on what the breeder desires. Hence, artificial selection can cause some problem traits to predominate in a species. An example is Dobermans, a breed of dog. Dobermans have been selectively bred for a certain appearance. In the process, a genetic
The Netherland Dwarf rabbit has a condensed body, with a small circular shaped face. The eyes often look out of proportion for its body. This breed has a short fur coat, with ears that are small, sit vertical and round tipped. There are many variations in colour for this breed, some of these colours include but are not limited to; chocolate, Himalayan, chestnut, black, blue, chinchilla, otter, merle, tan, steel, orange, fawn, sable, lynx, onyx, silver and sable marten and pure white (with blue or ruby eyes)
“Adaptation is repetition, but repetition without replication” asserts Hutcheon (2006: 7), stating that there are reasons why an adapter would decide to make certain changes. Regarding character development, the Grimm brothers’ compilation is quite similar to the original Sleeping Beauty tale in the sense that not much is said of the evil fairy in neither of them. The original tale describes the evil character as “a very wicked fairy (...) with an evil smile on her face”, and the Grimm brothers just call her “the thirteenth fairy”. In both versions, the reason why the fairy casts the spell on the princess is because she hadn’t been invited to the baby’s christening, and that is all we know about the character. Undoubtedly, the focus of the
Rabbits are strict herbivores and require a diet high in fibre. A balanced diet of grasses, hay and pellets needs to be provided in the correct ratio to ensure gastrointestinal tract motility. Adequate dental wear is required by high volumes of chewing of grasses and hay which minimises dental procedures. Rabbits require high quantities of fresh grass, dried grass products or hay and need up to 30-60g of dry food per body weight and containing at least 18% of fibre.
