Darwin and Wallace Island Finch Evolution Lab Experiment


Darwin and Wallace Island Finch Evolution Lab Experiment

Evolution and Natural Selection have been a recurring focus of biology throughout the years. This Particular experiment is based on Charles Darwin’s observations of finches made in the Galapagos Islands. He noted that different neighboring islands in the Galapagos had distinctly different types of finches. He theorized that this was caused by natural selection, where the environment determined the characteristics of the species in it. In the Evolution Lab Experiment, I looked at how beak size and population numbers for two hypothetical populations of finches on two different islands evolved in response to factors that I manipulated by changing environmental conditions. The specific environmental conditions that I chose to manipulate were the precipitation in the environment and the variance of the finches. However I only manipulated the precipitation and variance on Darwin Island and not on Wallace Island. I thought that if Darwin Island finches had less variance and less precipitation than Wallace Island Finches, that Darwin Island finches would be unable to effectively adapt in order to easily consume the type of seed that was a result of the lesser amount of precipitation. MATERIALS

The materials required for me to complete this experiment were my laptop and my University of Phoenix Student Website. Once I accessed the University of Phoenix Student Website, I was able to access the Evolution Lab, which is the final required material. An optional material that I chose to use was a pen and paper to take notes. PROCEDURES

In order for me to accurately test my hypothesis, I needed to first get to the Evolution Lab. Once I logged onto my University of Phoenix Student Website, I went to the classroom tab and clicked on Evolution Lab, which is found in week three. Once I pulled up the...
