Evolution Lab - Assignment ExampleOne particular animal, which gained Darwins attention, was the finches on the island. It was through studying these finches that Darwin came up with one of the most important terms in evolutionary biology which is one of the driving forces for evolution natural selection. Natural selection plays into the role that nature selects organisms, which be best fit for the environment. Those that have the traits that give them the best advantage in environmental conditions will blend and proliferate while those who have the inferior traits will not thrive and die out (Darwin, 2010). In this particular simulation, we were looking at what the effects of presumption on two separate islands and how it would affect the coat of the find fault on a species of finches. We are able to make this theory due to the fact that we populate that the amount of precipitation will influence the different types of flora and attainds, which will grow on the island. This lavatory affect size, hardness, and shape of the seeds and this will have a direct effect upon the size of the beak of the finch that inhabits the island. Our hypothesis was that of non-directionality, meaning that we did not know how precipitation was going to affect beak size in any(prenominal) particular direction, but we knew that the precipitation was going to have an effect on how flora grew on the island, soce this would have an effect on beak size. Materials Since this was an interactive simulation, very few materials were needed in dedicate to complete this lab. A computer with an active Internet connection was necessary in order to physical exertion the online simulation software in order to collect the data, due to the fact that this observational data would be impossible to be collected over the thousands of years. Methods The first step of being able to run the try was to log onto the site in order to carry out the experiment at http//www.biologylabsonline.com/axi a/EvolutionLab/. Next, depending on the experiment, the experimenter has the natural selection to set the variables that they are interested in looking at. For the case of our hypothesis, we are looking at beak size in relation to precipitation. The independent variable is the initial size of the beaks. The experiment calls for modifying the precipitation on the islands in order to see if this has an effect on beak size. On one island, move the precipitation to the extreme of there is no precipitation and then on the other island, move the precipitation to the level best amount of precipitation the island can have. Set the amount of time to look at over the ladder of three hundred years and run the experiment. Then look at and analyze the data to see if the data matches the proposed hypothesis. Data Parameter DARWIN WALLACE ------------------------------------------- Initial Beak Size 12.0 mm 12.0 mm Heritability 0.7 0.7 Variance 1.0 1.0 overtake Size 10.0 eggs 10.0 eggs Precipi tation 35.0 cm 20.0 cm Population 200.0 birds 200.0 birds Island Size 0.5 km 0.5 km Darwin ------ Wallace ------- Discussion and Results As can be seen from the graph, we have an interaction effect at the start and then both populations diverge from each other as time progresses. On Darwin Island, where the precipitation was sight to be 100.0 cm, there was an increase in beak size as time increased. On Wallace Island, where the precipitation was observed to be 0.0 cm, there was a decrease in beak size as time increased. found on this result, we can conclude that over the 300-year
