Exploration

Answer the following questions in fewer than 100 words:

Activity 1: Modes of Natural Selection

What type of selection is taking place on Wallace Island? Explain.

Directional Selection is taking place. The beak size is increasing on Wallace Island from 11.85 to 19.13, and the population is increasing as well. This is because there are more seeds available that the birds can eat.

What type of selection is taking place on Darwin Island? Explain.

Directional selection is taking place. The beak size increases slowly, from 12.47 to 26.95. The population decreased because of the lack of seeds available for the birds to eat.

Explain the reason for any differences in population numbers between the two islands.

The population increased on Wallace island because there were more seeds for the birds to eat, meaning there was more of a chance for them to survive and reproduce. The population decreased on Darwin island because there were no seeds for the birds to eat and without an abundant food supply they...
