    would like to see the outcome of beak size and population as the finches on the island evolve with different controlled environments. The environment on the islands can be changed by island size‚ precipitation‚ and diet. What will happen to the birds over 100‚ 200‚ or 300 years? I think that if the precipitation on the island is higher then the seeds will be softer and the birds will evolve smaller beaks to eat the softer seeds. If the seeds are harder the beaks of the birds will be stronger and

    seeds to be produced. 2. a. The beak size of 12 mm is relatively shallow compared to the available range from 10 mm to 30 mm. b. The shallow beak size of 12 mm is not suited for the hard seeds that are available because of the low rainfall of 20 cm. 3. The beak size went up on the islands as time progressed because only hard seeds were available to the finches. Therefore the average beak size increased over time because the trait of larger more deep beaks were more suitable for survival in

    precipitation will influence beak size. • Variances in beak size will influence beak size. MATERIALS The materials needed for this experiment consist of a computer and access to the Evolution Lab on the University of Phoenix student website. In the Evolution Lab there are two islands‚ Darwin Island and Wallace Island. There are seven variables that can be changed to run many different experiments on both islands. The variables are beak size‚ variance of beak size‚ heritability‚ clutch size

    Hypothesis: If a species of bird is able to adapt and maintain a curved beak‚ then that species of bird will survive and benefit from the process of natural selection. Background: Natural selection is a gradual‚ non-random process in a population of biological traits becoming either more or less common as the population progresses or digresses through generations. In this lab‚ various beak phenotypes were tested to see which beak phenotype was best suited to withstand and survive the process of natural

    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

    finches in EvolutionLab‚ the depth of the beak is the quantitative trait. You will investigate how this trait changes under different biological and environmental conditions. You can manipulate various biological parameters (initial beak size‚ heritability of beak size‚ variation in beak size‚ clutch size‚ and population size) and two environmental parameters (precipitation‚ and island size) of the system‚ then observe changes in the distributions of beak size and population numbers over time.

    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

    heritable. In EvolutionLab‚ beak size is a trait that affects survival. Birds with small beaks are more efficient at utilizing small soft seeds whereas birds with large beaks are better at utilizing large hard seeds. Therefore‚ when more small seeds available‚ birds with small beaks have a higher rate of survival than birds with large beaks. Conversely‚ when more large seeds available‚ birds with large beaks have a higher rate of survival than birds with small beaks. Thus‚ beak size satisfies the first

    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.

    environments of the finches. For instance I doubled the size of the clutch‚ beak and population of the finches in Darwin’s island‚ since Darwin’s Island is about doubled the size of Wallace Island. I also increased the amount of seeds available as well as the variety of seed available to the finches on Darwin Island. My hypothesis is that the finches on the Darwin Island will increase in population and clutch size and that their beaks will increase in size due to the various types and amount of seeds available
