Natural Selection
Introduction:
Natural Selection is the ability to survive and reproduce in a given environment. It is known due to evolution that has occurred over time and how mutation, migration, and genetic drift have changed. There is a variation in traits in animals, for example some birds have bigger beaks that can be used to feed on worms and bugs that are way underneath the river and lakes. Also there is a differential reproduction that occurs because not all animals can reproduce the same amount and there is a limit that the environment can support over time. Some bugs due to their color can be an easy target for birds to eat and makes it harder for them to keep reproducing the same trait. In natural selection there is also heredity

As they started to produce more offspring’s and competing for food it made it harder for longer beak birds to gather more worms in order to survive. Over a period of time natural selection limits the quantity of animals in the same population. Smaller beak birds encounter a hardship because they couldn’t obtain the worms underneath the tank and longer beak birds would feed on floating worms as well. Competition on both long and short beak birds occurred in the experiment and over time the population for small beak decreased. What can be concluded is that longer beak birds eventually got overpopulated and would stop producing offspring’s because its in their nature to limit the amount of animals in one population. 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 …show more content…
Mutation did occur in some of the rounds we did in the experiment by having more birds with longer beaks and smaller ones decreasing dramatically. But eventually birds with smaller beaks will adapt to another environment and as for long beak birds they will have to challenge one another to fight for food and probably over time have a hard time searching for food. But it wasn’t natural selection that changed the beak size of the birds it was basically a mutation that was passed on to their
Skittlefish Lab Report
598 Words | 3 PagesNatural Selection is the concept that organisms better adapted to their environment tend to survive and produce more offspring. This leads to the creation of populations and diversity of life within them. In the Skittlefish Lab, many separate occurrences can be observed which detail and explain how Natural Selection works on a population over a period of time. Certain adaptations in a species in its entirety may display how individuals impact the whole population as they pass their traits onto their offspring, which do the same. This lab required students to observe the individual “Skittlefish” and “Sea M&Ms” in different environments as they camouflaged and hid from predators.
Mcgraw Hill Higher Education: Natural Selection-Virtual Lab
877 Words | 4 PagesParagraph 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.

Sinsauropteryx Thesis
276 Words | 2 PagesThe professor refutes this point by saying that feathers might have other functions than flight. The professor gives and example of B-cock, which has a colorful feathered tail, that is used to display to attract mate. The professor explains that analysis showed that Sinosauropteryx had a colorful orange white feathers, which supports the display function of the
Drab Guppies Lab Report
1015 Words | 5 PagesFirst of all, we are human and could’ve incorrectly inputted data into our tables. Although we tried our best to record everything as accurately as possible it always feasible that we could’ve recorded something wrong. Another error is that we never tested our hypothesis on an even mix of bright and drab guppies, the data could be totally different than what we collected. We also never had a trial with thirty Rivulus and thirty Acara which might have also given us a different result. One major area where this lab could be inaccurate is that it’s a simulation.
Examples Of Irreducible Complexity
2350 Words | 10 PagesPro-evolutionists use examples of creatures with partial wings that enable gliding (as supposed to flight), such as the flying tree squirrel, the flying lima, and the gliding lizard, but all of these flying/gliding devices are actually flaps of skin between the limbs which specifically offer the function of gliding and not flying. Clearly, these cannot be used as examples for demonstrating how the wings of birds developed as they are completely different structures, offering a completely different function, which anyway would have appeared to have evolved
Argumentative Essay: Stop Feed Birds
853 Words | 4 PagesBirds get fed by people all around the world and if they are not able to feed them for a little while, they will die. Let us think about it if you had been fed your whole life by your
What Are The Arguments Against Darwin's Theory Of Evolution
1126 Words | 5 PagesThere 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.
Red Queen Model Vs Court Jester Model
119 Words | 1 PagesThere are 2 ways to look into evolution, it’s either by Red queen model or Court Jester model. The “Red Queen” model come from Darwin, it’s an evolutionary hypothesis which proposes that organisms must adapt, evolve, and survive to gain reproductive advantage. In a Red Queen world, the species diversity is depends primarily on body size, width of physiological tolerance, or adaptability. The Court Jester model is different from Red Queen model because evolution, speciation, and extinction rarely happen except in response to undeterminable changes in the environment. In a Court Jester model, species diversity depends on unfaithfulness of climate, landscape, and food supply.
Predator-Prey Lab Report
1347 Words | 6 PagesOrganisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey
Advantages And Disadvantages Of Artificial Selection
722 Words | 3 PagesArtificial Selection/ Natural Selection When the word artificial comes to my mind fake thoughts run through me, like water runs down your throat. Artificial christmas trees, flowers, foods, anything artificial you can think of, almost everyone has it and has produced it. As you read this, do you have any idea what artificial means? Said on dictionary.com, artificial means produced by humans, not occurring naturally. For example, artificial selection would be taking a wild animal, such as a whale, living in the huge ocean and putting him/her in a place like Seaworld, where they don’t adapt to the environment well, and are not used to the resources and rules.
Charles Darwin's Influence On The Galapagos Islands
502 Words | 3 PagesOn the Galapagos Islands, Charles Darwin study different species. He observed that some of the same species differ from island to island. The Galapagos finches are one of the most important studies that he did in the Galapagos. He studied all sorts of different finches and concluded that each each bird had a different beak that were adaptations to different diets available among the islands.
Natural Selection Lab Report
455 Words | 2 PagesThe overall objective of this experiment was to observe natural selection, like genetic drift, of Drosophilas and how it contributes to the changes in allele frequencies over time. The lab was performed by starting with 10 wild-type males, 10 white-eyed amles, 10 wild-type females, and 10 white-eyed females into a population cage with 4 food bottles and their phenotypes were counted to observe the changes in the populations. Population genetics is a branch of biology that investigates the genetic makeup of biological populations as well as changes in genetic composition caused by different variables such as natural selection (Okasha, 2022). It investigates genetic diversity within or across groups by detecting and simulating changes in the frequency of genes and alleles in groups through time (Okasha, 2022).
Galapagos Finch Evolution
190 Words | 1 PagesIn the news article World News, Gautam Naik did a study on Galapagos Finches. He has identified a gene in Galapagos finches studied by a naturalist Charles Darwin that shows a unique beak shape and that played a role in the birds' evolution over the past hundreds of years from a common ancestor. The studies show the genetic formation of evolution, including how genes can flow from one species to another, how different versions of a gene within a species can contribute to the formation of new species, and how they can be transferred into another bird or species from genes. These birds have a different beak shape from other birds in the world. Thier beak can differ from how to get their food, how they eat, and how they hunt to find their food.
Neutral Theory Of Natural Selection Report
683 Words | 3 PagesUnlike natural selection, genetic drift is random and rarely produces adaptations to the environment. It is important to note however that the neutral theory does not suggest that: organisms are not adapted to their environments; all morphological variation is neutral; all genetic variation is neutral and that natural selection is unimportant in shaping genomes. It in facts believes that natural selection helps to rapidly purge the genome of deleterious
