Natural Selection: Altering Species Of Animals

The purpose of this lab is to better understand the process of natural selection and its effects on a population by conducting a stimulation. The stimulation consist of predators (students with either a spoon, fork or a knife) and prey (different types of beans). Furthermore, students will be able to determine how phenotype (bean color and utensil used by the predators) influences natural selection. Students will also demonstrate their quantitative skills by determining the predator survival and reproduction, bean survival and reproduction, and by calculating the total percent of the population. Additionally, students will be able to identify the occurrence of evolution by natural selection after the end of generation three. Moreover, students

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

One thing about natural selection that many people do not understand that natural selection does not increase the odds of survival for a species, but for individuals in that species. This makes sense when someone considers humans. Humans live in many social cultures, where for instance, the odds of survival in a group can be improved by the selection of certain traits that does not improve an individual’s odds of survival. Coyne states, one never sees the type of adaptations that benefit the group to the detriment of an individual (p.122).

A. Rus hoelze et al, studied the impact of intense hunting of Northern Elephant Seals in the late 19th century, whose genetic variation reduced due to this bottleneck. This reduced their population size to just about 20. They found that although it has since rebounded to over 30K now but compared to their southern counterparts i.e., Southern Elephant Seals they have much less genetic variation. The Southern Elephant Seals didn’t went through this bottleneck event. It is clear that the genes of Northern Elephant Seals still carrying the marks of this bottleneck.

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.

The reason for this is because a lot of organism that are around today were closely related a one point ("Comparative Anatomy."Pg.1). Sometimes these similarities are conscious. A good example of anatomy that are humans and primates and also crocodiles and alligators ("Comparative Anatomy."Pg.1). Even species that are far off even humming birds and whales. When looking at these different species you see the natural selection happening in each of these by how their anatomy gets better suited for their environment ("Comparative

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

Evolution through natural selection is not a controversial topic. It is not controversial because religion preaches that the maker made each individual species. Many times religion teaches that each individual has a purpose and is created for a reason. Evolution claims that living species can change over time and give rise to new kinds of species, with the result that all organisms ultimately share a common ancestry. That being so, people can believe in both. In a religious view people can be correct and people who believe in evolution can also be correct. Evolution can be true for religion that the maker has made each individual species, he/she started it all with one species and through time the world has changed

Darwin: Well in that case I suppose that it could affect natural selection in that if a food source or necessity is changed that it could encourage recessive phenotypes but overall the ones best suited for the environment would be able to survive.

In chapter two, the class learned about natural selection: the primary mechanism of evolution. For example, two types of birds inhabit an island. One type of bird has a strong beak, great for cracking the shells of nuts (the main food source on the island). The other species has a weak, small beak and struggles to find a consistent food source. Eventually, the bird with the smaller beak will die out, and the other birds with the stronger beak will continue to survive. If a gene or characteristic allows an animal to adapt to the environment, then it is considered successful and will be passed on to the next generation. Certain characteristics, such as a strong beak, can allow a species to survive a catastrophe. Another form of an adaptation

This week I found that talking about evolution was actually interesting. There are multiple explanations on what people think evolution is and I think it was interesting to look at all the misconceptions of it. Something that intrigued me was that natural selection leads to adaption, not organisms “trying” to adapt. When my group answered this question on the card, I did not even realize that as humans we do not try to adapt because adaptation just happens. It is important for people to know that natural selection involves the adaptation of everything around us, but we do not try to adapt to the situation. The process of natural selection does not involve trying to adapt, but leads to adaptation itself.

GMO stands for Genetically Modified Organism, which is the process of extracting genes from one species into another unrelated species. The process of transferring DNA from two distinct species is through genetic engineering. This displays the new traits of the first donor, which will be part of the genetic make up of the recipient organism. GMO is different from cross breeding or hybridization. Scientists developed GM plants by introducing genes that kill insects and protect crops against viruses. Many of these GM plants require less water so that they are able to grow in areas where water is scarce. The benefit of GMOs help crops grows and ripens faster so that farmers are able to grow more crops throughout the year. On the other hand, GMOs may be harmful to humans if they are not washed and cleaned properly before eating. GMOs include high risk of allergens, toxins, and other unknown side effects that are harmful.
