The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population, and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining life, when changing the beak size to a much larger size we will see that the finch will have no need for further evolution of its beak and that its population will become much more stable and consistent throughout the years.…
The average beak size is 12.0 mm, while precipitation averages 20.0 mm at Darwin and Wallace Islands. The data from the samples were input onto an excel spread sheet, which calculated the data for the next 100 years. If the rainfall was to average 20.0 cm for the next 100 years, the finch beak size would increase. If the precipitation continued to average 20.0 cm, by 2096 the finch from Darwin Island would grow a beak of 18.5 mm. The finch from Wallace Island, would grow a beak of 18.21 mm.…

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?…
1. As discussed in Module 2, the beaks of the Galapagos finches changed during the 1976-1977 drought; they became deeper (stouter).…
The Evolution Lab experiment of finches located on two separate islands was conducted with purposes of evaluation and study of important principles of evaluation that include adaptation, natural selection process and finally the evolution process as a whole. In this study, "Darwin Island" and "Wallace Island" are lab environments that were used to conduct the experiment. By manipulating vital parameters that influence adaptation, natural selection and then following how the changes influence the evolution of beak size and population numbers for the two different populations of finches over selected time intervals, the evolution…
Evolution is a natural process in which animals adapt to their surroundings so that they may survive. There are many variables in an animal’s environment that influence its evolution. The purpose of this lab is to examine finches from the island of Darwin and the island of Wallace and how the island size, finches’ clutch size and the precipitation on both islands directly affect the finches’ beak size and population. I believe that a larger island size, larger clutch size and high precipitation will lead to a smaller beak size and larger population.…

‘The Birds’ was far most one of the most successful suspense films of its time and possibly all time. It is directed film by one of the great founding films for the horror Alfred Hitchcock. The movie was based on a novel by Daphne DuMaurier, I think this is a extraordinary, exceptional film because it does everything a suspense film should have, and Hitchcock went beyond. I am proceed to examined special effects such as lighting, color and camera techniques.…
If you want a bird who can talk, a Quaker parrot is the one you're looking for because parrot Quaker training is easy. It is a fast-learner, develops a bond with the owner and loves to be around people. Results would be better if just one member of the family would teach a parrot how to talk. Even so, you can hear the bird imitating the other members of the family as well.…
This same issue was observed by Darwin and with the finches of the Galápagos Islands, led to his discovery. The Grants observed how variability itself can also be different species to species. They decided that Darwin's “hypervariable finches, despite their secluded home, might have well been the key to a crucial breakthrough in our knowledge of evolution. Soon they started to collect measurements on twenty-one different kinds of finches that they found on seven islands. The potential in their project became apparent in such a short amount of time. Their measurements and mathematical analysis that were allowed by modern technology exposed a rate of variability in species, which remained unknown by scientists until…
As illustrated by Anne Lamott, author of Bird by Bird, first drafts are not meant to be perfect, but merely to begin the writing process and generate ideas that can later be perfected. Lamott attempts to eliminate the common perceptions of the writing process, emphasizing the need for accepting flaws of an initial draft.…
The first experiment is designed to study the influence of beak size on finch population numbers. For finches, deep beaks are strong beaks, ideally suited for cracking hard seeds, and shallow beaks are better suited for cracking soft seeds. I experimented first with the finches’ adaptation and evolution of their population over 300 years, and changed the Wallace birds beak size to 28mm, and Darwin’s birds stayed at the default of 12mm.…
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…
Continue on the movie, it's the part of the scientists did a research on the humming birds. They wrote down all information on the humming birds they'd caught on different places including took some of their DNA. All These humming birds have different beaks to adapt on the individual climate even if they have similar DNA. The environments where they live force them to adapt to survive. Humming birds which live near the equator where day is hot and night is cold can drop 15 degree on their body temperature to fit in the environment. These humming birds must have the same ancestor, then, because of some reasons, they must change their living…
