Modern Day Species Evolution Lab Report

Are you interested in the evolution of the modern day species and how they have changed from thousands of years ago? Scientists and many people say it's because of evolution. Evolution is when different kinds of organisms have developed from earlier forms during the history of the earth. There are a lot of reasons and explanations why species have changed do to adaptation, competition, and history are all big factors.
Competition changes a species by how the species fight to save themselves and family. It is hard for these species to all get food especially if there is more than one species. The fruit loop activity we had to compete for the most fruit loops, the person who had the most fruit loops was the survivor. The species who survive are the ones that can mate and reproduce. You need to be fit and fast to be a good competitor. In the beak lab, you had to get a certain amount of seeds in a 30 second time period. If you had gotten enough seeds, you won and lived on to pass your genes. To be able to collect the food needed a species that cant fight for themselves is gonna have a hard time staying alive let alone reproduce. …show more content…

The stickleback fish lab is a good example because they took the fish from two seperate places and had used a die to really see how different these fish are. The NOVA lab is also a good example because it shows the different trees of these species traits. DNA had affected these species greatly. These species have to be able to adapt physically and mentally to the environment and figure out how to live that way to be able to produce offspring. For example fish or a species have to adapt in their own ways. Not one species can do the same thing and be comfortable doing

Beak Lab Analysis Charles Darwin , a naturalist, discovered and stated that organisms arise and grow and develop through the natural selection. Natural selection is the process in which nearby organisms well adapted to the environment to survive and to produce offspring. In class we did a lab where we studied the amounts of food birds get with their different sizes of beaks. For an example, we use a spoon to represent a larger beak I found that it was harder to pick the food.

Paragraph 1: Introduction - explain your lab. The lab that I chose to do was the “McGraw Hill Higher Education: Natural Selection - Virtual Lab.” I chose this lab because it was the one that most interested me, as I liked the format of the virtual lab. In this lab, I was able to manipulate both the environment and the allele frequency in order to record and investigate the generational breeding patterns of a group of organisms.

Anth. 105 Human Species – Lab 3 Report Sirin Gul November 11, 2017 Introduction In Lab 3, we examined the relationships between diet quality, tooth shape and daily travel distance. Evolution has changed how humans and other primates live and survived according to their environment. They are relatively related/similar to each other when it comes to fossil hominins, humans and other primates.

ABSTRACT The purpose of this lab is to determine the effects of natural selection on the populations of predators and prey. Beans representing “prey” were scattered in a grass field. Forks, spoons, knives, and forceps were used as “predators” and were placed in an area to see which was best adapted to the environment. In the end, forceps managed to catch the most prey.

Introduction The purpose of this lab was to visually show how evolution occurs through natural selection. The lab showed the gradual development of the prey and predators throughout the generations. The way the “species” evolve is natural selection, in which better adapted species survive and reproduce, creating more of the adapted species. The predator adaptations are skills and traits represented by the plastic cutlery that are developed through evolution and natural selection and help them catch prey.

I conducted a lab that would investigate the question of whether or not camouflage favored natural selection. If an animal blended into its surroundings, I wanted to know if it could more effectively evade predators and survive as a species. I hypothesized that if I were a predatory bird hunting for mice in a field, then the mice that were camouflaged with their environment would be harder to find. The results did not support my hypothesis, as most of the mice (often more than 2/3) that had a similar appearance to the field they lived in were hunted, and did not escape predators. You can determine if a predatory bird would have more difficulty finding mice that were camouflaged with their environment.

Abstract Natural selection is investigated in this lab with the use of varying plastic phenotypes represented by spoons, forks, and knives to determine if natural selection will occur. Each phenotype went through five generations competing against each other for food to determine if they will survive and reproduce. We hypothesized the spoon phenotype would be the most suitable trait to obtain food, therefore being the adaptive trait through evolution. After the simulation, it was confirmed the spoon was the dominant phenotype suggesting natural selection and evolution did occur. Introduction Natural selection is a major factor in determining which individuals survive and reproduce, often decided by limiting factors such as food, space, or

This would leave a yellow species capable of breeding and producing even more yellow, therefore evolving into another yellow-only species over time. Eventually with the extinction of green and red the yellow population count will slow down, yet still thrive. As a new species was not created the model of natural selection did not work. In order for the experiment to show natural selection a new species would have to be formed which is incapable of breeding with the initial species. Over more time the surviving population would develop mutations in its gene pool, leading to a new species that is not shown in this

In simple words is just the rate of reproduction and mortality. Those organisms who successfully adapt to the environment survive and reproduce organisms able to adapt and survive too. The purpose of this activity is to see how natural selection happen and see which animals evolve and adapt to their environment in order to survive. Animal struggle for existence,

Also the decreased of small bird beaks could also have an advantage such as being able to fly faster and feed quickly on worms or insects thatmmm are floating in water. So my hypothesis of longer beak birds having a better chance feeding on floating worms and underneath ones was accurate after conducting the

All of these changes have required animals to adapt and change at a rather fast pace. The organisms that couldn’t adapt to this change die off and the stronger organisms breed to make the species stronger and create a new trait. Examples of these changes would be species migrating, reproducing more or developing faster. Some physical changes include longer necks wider wingspan thicker or thinner fur depending on the climate in the

The competitions include fighting for limited resource of food, female for mating. As a consequence, the fittest organisms win the battle, and survive. The others lost the fight and lost their lives. This is natural selection. Giraffe used to have a short neck.

Over time species have evolved due to four forms of evolution: mutation, genetic drift, gene flow, and natural selection. Mutation is the evolutionary force that causes a completely new allele to be produced from one generation to the next. It is the only form of evolution that has the ability to create new alleles. This can be seen through different genotypes and even phenotypes found in a species. Plainly put, a mutation is a genetic error, it was not supposed to occur.

There are a least 14 species of Darwin’s finches that have developed over millions of years. When Darwin encountered the finches on the Galapagos Islands he noticed the diversity of the Finches beaks and size compared to each other. In Figure 1 you can see this. The diet of nuts and berries that the finches had access to on the island is greatly related to the size and function of the finches beaks (Grant, 2003). The larger beaked birds fed off of hard shelled nuts, while the smaller beaked birds fed off of smaller seeds and nectar from plants.

Introduction: Biodiversity is important for all living organism including plants and animals. Without biodiversity, there would be no balance between organism and their environment. Biodiversity helps to maintain the balance of nature to sustain all life on earth; one species will not overpower another because of the effect of biodiversity. Not only does biodiversity maintain the balance of nature it is also used to indicate health in the aquatic community. Dissolved-oxygen is measured in the aquatic environment to test the health of the water.
