Darwin &Wallace Finch’s beak size.

1. The three types of seed that finches can eat are hard seeds, medium seeds and soft seeds
2. The precipitation affects the seeds in different way. If there is no precipitation then there are a lot of hard seeds and no medium or soft seeds. If there is medium precipitation, which is measured by 50 cm then the medium seed is in abundance with 50%, the hard seed is about 25% abundant and soft seed is 25% in abundance. When there is 100% precipitation the soft seed is 100% abundance.
3. If the finches have little beaks then they can only eat soft seeds because the soft seeds are smaller. The smaller beaked finches might be able to eat some medium seeds but they will stick mostly to the soft seeds because it is the easiest to eat for the small beak finches. The large beak finches with are able to eat the hard seeds and the medium seeds but no soft seeds because they don’t be able to get them with their huge beaks.

5. The larger beaked finches will be able to have a faster growing population and the smaller beaked finches will have a population that grows slower but over time their beaks will grow large.

a. Darwin’s finches started out in 1997 with small beaks and the population grew slowly and in the first 100 years the beak size only grew by 4.00 mm but the population only grew by an average of 138 finches. After the 100-year mark the beaks grew from 14 mm to 16-22cm in the next 150 years and the population grew by an average of 325 finches.
b. Wallace’s finches started out in 1997 with large beaks and the population grew super fast in two year from 200 to 743 and their beak size only dropped in size by and average of .20 mm. In the next 248 years the finches beak size only fluctuated by .60 mm on average but the population fluctuated from 781 to 877 after the first two years.
7. The types of seeds change in abundance due to the precipitation so if there is 100% precipitation then there...
