g When the weather changed drastically on the island of Daphne Major individuals with a particular beak size were more likely to survive. In this activity, you will analyze some of the actual measurements that Peter and Rosemary Grant collected. You will interpret their data and suggest hypotheses to explain their observations. Based on this data you will also propose how and why some characteristics are more likely to change from one generation to the next under specific environmental conditions.

Beak size has a great influence on the survival of birds in specific environment.

Explanation:

Peter and Rosemary Grant evaluated from their study that the beak size plays a key role in the survival of the birds. During the study, they concluded that due to heavy rainfall, large beak finch has more survival rate than small beak finch due to availability of food sources whereas the small beak finch having difficulty of searching of food because the heavy rainfall washed away all small seeds which is the only source of food of these small beak finches. Some characteristics are more likely to change from one generation to the next generation because these changes are necessary for the survival of that organisms in that specific environment.
