Evolution Lab
The evolution lab report is based the theory of Darwin and Wallace and determining the
type of seeds the birds feed on an average rainfall in the island of Galapagos. The birds in this
experiment live on the island and survival is not easy and it is baking hot during the day, freezing
cold at night and there isn’t much food available. Because of this, the birds have very
specialized feeding behaviors.
An example of evolution resulting from natural selection was discovered among birds
living in the Galapagos Island. These birds have varieties that vary in what they eat and their
appearance. The specialization developed allowed the birds to survive during the dry season or
times of drought/low precipitation when little food is available. Then this specialized tool allows
the birds to better compete for food resources with other birds and animals.
The objective of this experiment is to differentiate and determine what happen when the
parameters are changed over time between the Darwin and Wallace report. The first experiment
is meant to study the influence of beak size on the birds’ population numbers. Deep beaks are
suited to crack hard seeds, and shallow beaks are better suited for cracking soft seeds. To test out
the hypothesis, I was able to change the beak size of Darwin to 17.0mm and let Wallace Island at
12.0mm. By doing so, the average beak size rose over time whereas it fluctuates for Wallace.
The clutch size was changed from 10 eggs to 30 eggs for Darwin and left at 10 eggs for Wallace
as well as population of 600 and 200 respectively. I also wondered about the changes of bird
beaks from island to island. When I changed the cm on the beak, I was able to conclude that
these numbers help them adapt to the island and make them more fit to survival on available
food.
