The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other, placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island, which is 1 km, and the other population of finches are located on Wallace Island, which is about half the size of Darwin island. I have altered the 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 to them. In addition, I believe that the population of finches on Darwin Island will be able to maintain their population size if not increase. On the other hand, I hypothesize that the population of finches on Wallace Island will decrease as well as their clutch size and their beak size would stay the same size because of the small amount and variation of seeds available on the island, resulting in a possible distinction of the species on the island. The materials I used to conduct this experiment included a computer and access to the Evolution Lab available on the student website.
So the first thing I did to conduct this experiment was go the Evolution Lab website. From there, I manipulated the traits from each population of finches, as well as their environmental conditions. Then I adjusted the traits and environment of the finches. For the finches on Darwin
