The object of this experiment is always to determine how changing the size of the beak of a finch will certainly affect the population as well as the growth rate of the finch's beak.

In this experiment I will display that the finch will always evolve until its beak has come to the optimal size for keeping 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 their population can be much more steady and constant throughout the years.

The only supplies I will requirement of this test are simply just the evolution lab applet. This applet contains all the information must be able to adjust the characteristics of the finch and find out the final outcome over a very long period of time.

Then I performed my second experiment changing the beak size towards the maximum allowable size of 30mm. I remaining all the other variables alone (as seen in FIG. 2) so that I would manage to clearly see how this would impact the bird's progression and populace characteristics. From this article you can see in all the fastened charts changing just that one characteristic may have a huge effect on the finch and its population. FIG. you FIG. two
