Select one animal species. Your main goal is to describe the manner in which an evolutionary change might take place for a specific characteristic (trait) of a population of that species as a result of natural selection.

The characteristic (trait) could be something similar to coloration pattern, length of the limbs, size of the teeth or beak, or any measurable trait which is inherited.

The organism you select should be a real one however the evolutionary change in a trait that you describe can be real or fiction.

In your own words:

Q1. Describe how the change in this trait takes place. You will describe the trait in the population at the starting point and then what the trait will appear like at a later time, as an outcome of natural selection.

Q2. Make sure to describe the method by which the changes occurred. What is the selective pressure? Describe why the change might confer more fitness to a specific environment?

Tips: Make sure to comprise the given in your answers to a and b above:

Clearly state the name of the species you are going to be talking regarding for this assignment. (Make sure you know what is meant by the species.)

As well, clearly state what population of the species you are going to talk regarding by specifying its geographic location. (Make sure you understand what a ‘population’ is.)

Clearly define the characteristic (trait) of the population which you are going to be talking about and describe how this trait differs among the individuals.

Describe what change takes place in the environment which causes a change in the above feature.
