How does change in precipitation changes beak size, population and the size of seeds?

By: Karen Ann Weeks
Dr. Tomáš J "Doc" Oberding
January 20, 2013

Introduction and Purpose
Hypothesis – When changing the level of precipitation which changes the seeds to hard large seeds the finches with the smaller beaks with become a smaller population when changing the precipitation which changes the seeds to smaller soft seeds will increase the population no matter what size of the beaks.
This experiment is being done to study natural selection, speciation, and human evolution. Although no humans are being observed in this lab the concept of evolution is going to be looked up. The speciation is to see if by different modifications in the environment create a new species of finches. If no new species develop or the finches do not evolve to the changes in their surroundings will natural selection happen and will we no longer have finches on this island?
Materials

Run the report 4. Change the precipitation on Darwin Island all the way up to 0 cm 5. Re-run the report 6. Change the precipitation on Darwin Island all the way up to 98 cm 7. Change the beak size all the way up to 30 mm 8. Re-run the report 9. Change the beak to 10 mm 10. Change the precipitation to 98 cm 11. Re-run the report 12. Change the precipitation to 0 cm 13. Change the beak to 10 mm 14. Re- run the report 15. Change the precipitation to 0 cm 16. Change the beak to 30 mm 17. Re-run the report

    A small population of finches have been discovered on Darwin and Wallace Island. The population is 200 finches at Darwin Island, and 200 finches at Wallace Island. The year is 1997, and scientist measured the finch beak size from both Darwin and Wallace Island. The finches from both island, showed an average beak size of 12.0 mm. Precipitation on both Darwin and Wallace island average 20.0 cm. Scientists want to determine if precipitation was to increase, would the finch beak increase in size? In this lab study, scientist will be measuring the amount of precipitation within the discovery of the finch on Darwin and Wallace island, and collect data to prove that the finches evolved a larger beak due to the increase of rainfall.…

    The Galapagos Finches live on the small island deserted island of Daphne Major. Daphne Major is a island in the Galapagos islands. The island is very small and doesn't even have any trees on it. The island is home to owls, hawks and the Galapagos Finches. Around 1977 all the finches started to disappear. A drought started so then it didn’t rain then so the seeds didn’t grow. It only rained 25 centimeter when it usually around 150 centimeters rains, it shows this in the rainfall graph.…

    A local chicken farmer heard a lot about the bird flu so he freely decided to apply monthly physicals for his chickens. An observation made is that chickens have a body temperature of 104 degrees Fahrenheit. That worries the farmer so he decides to conduct an experiment to try to figure it out. The question is “Do the chickens have a fever?” According to the information the cells are composed of hundreds types of enzymes and each one has a specific role in a reaction. When the shape of an enzyme changes it also becomes effective for its specific function. Although that is the case, the enzymes tend to be less effective when it in extreme temperature. In order for the enzyme to work best, the temperature…

    In the 1970s, an investigator named John Endler traveled to Trinidad in the 1970s to study wild guppies. The guppies live in small streams that flow down the mountains from pool to pool. The experiment will take part on an online simulation of Endler's work. The group of members is responsible for collecting data, formulating a hypothesis, and running a series of experiments. They will find out about the interplay between natural selection and sexual selection in this wild population of guppies. They will ultimately find out the effects on the guppy population and their color distribution depending on the predator that lives in their environment. Endler wondered how the trade-off between attracting mates and affecting predators affects the coloration in male guppies. In pools that had few predator species, male guppies tended to be brightly colored, whereas predators are causing guppy populations to become drabber. This occurs because the predators are preying on the most brightly colored individuals and eliminating them from the gene pool. Therefore, guppy populations are evolving to more closely match, or stand out from their environment. Endler hypothesized that intense predation caused natural selection in male guppies, favoring the trait of drab coloration. He further tested his hypothesis by transferring brightly colors guppies to a pool with many predators. As he predicted, over time the transplanted guppy population became less brightly colored. Females tend to look for the bright colored male guppies in the pool and mate with them. This enables those males to have a higher probability of passing their genes on to their next generation. In the simulation, predators can dramatically influence the evolution of a population of guppies, but change does not occur quickly during the testing of one generation for each trial. (Before columns on graphs in the Data section of the simulation report) Scientists believe that they see changes in just a few…

    The first thing that occurred is the drought in 1977 they saw that after the drought many of the dead finches were the finches with the smaller beaks, while the ones that survived had bigger beaks. This happened because through the drought the most common food was the bigger seeds and the smaller beaked birds couldn't break into those seeds as well as the bigger beaked birds, so because of variation of beak size the more suitable beak size was found and thrived while as you move away from that best size you begin to see less survivors. The thing that is even more amazing is the fact that after that happened it rained for a very long time and they saw another case of natural selection because as it rained the bigger beaked birds couldn't get the more abundant seed from vines so the littler beaked birds survived better in the new…

    The beak of the Finch is a film based in the Galapagos Islands. This film is talking about the thirteen-different species of finches that are currently on the Galapagos Islands. The study of the species on the Galapagos originates all the way back to the late 1800s when Charles Darwin was first discovering the processes of evolution and natural selection himself. Scientists are still conducting experiments today on the different ways that species are evolving. Some of their findings would most likely shock Charles Darwin. Biologists Peter and Rosemary grant are also trying to find out how species arise. They are doing studies on of the smaller islands called Daphne Major. The grants have been studying the island for 40 years and have been coming…

    Like other aquatic animals, goldfish have a one-way flow respiratory system. This means that their respiratory system pumps water through their gills and back into the water supply to absorb oxygen. Gills--which are the organs that most aquatic animals use to breathe--consist of complex filters that extract oxygen from the water.”…

    On the other hand, there are genetic changes within a given population and while these changes may not lead to speciation it can cause populations of a species to vary from one another in the frequency of specific traits. Evolution such as this is known as microevolution (Jurmain et al. 5). Moreover, the similarities between macroevolution and microevolution are that they both heavily rely on the following evolutionary factors: mutation, gene flow, genetic drift, and natural selection (Jurmain et al. 97-102). A great example of microevolution was described in the nineteenth century by Charles Darwin when he discovered 13 varieties of finches and…
