• What was your hypothesis for selection on seed traits?
Larger seeds will be grabbed more due to being more visible. Smaller seeds will blend in more with the small rocks.

• What was your hypothesis for selection on seeds and changing the environment?
Larger seed size will be easier to see and grab since the smaller seeds will go deep in the ground. (grass environment – increase visibility)

• What was your hypothesis for selection and a small population of seeds?
Birds will different abilities to collect different seed size. Smaller population will effect the rate of change

• What was your hypothesis for selection on beak traits?
Chopsticks will be easier to grab seeds because the chopsticks will be able to have a better grip on the wings.

Expert Solution

The hypothesis for the selection on seed traits:
The seed size makes the seeds either visible clearly or are get blend in more with the small rocks. Thus, the larger seeds can be grabbed more easily than the smaller seeds.

The hypothesis for selection on seeds and changing the environment:
The seed size determines whether the seeds can go deep in the ground or can be easily visible from above the ground. Accordingly the smaller seeds go deep in the ground and are not visible whereas the larger seeds can be easily see in from the surface of the ground. Thus, the seed visibility in a given grass environment is determined by its size.

The hypothesis for selection and a small population of seeds:
Different birds have different abilities of collecting different sized seeds, but smaller population of birds will effect the rate of change.

The hypothesis for selection on beak traits:
Seeds can be easily grabbed by the chopsticks because of their better grip on the wings. Thus, the beaks which are like chopsticks will be able to hold the seeds very effectively and these types of beaks containing birds will be selected by the nature for their survival and reproduction.
