describe General

As-per to the Theory of Evolution and Natural Selection is the mechanism by which evolution occurs.

Beneficial traits survive longest and leave the most offspring a process known as Natural Selection.

Choose an animal species. Your goal is to define the way in which an evolutionary change might arise for a particular characteristic (trait) of that species as a result of natural selection. The typical could be something like coloration pattern, length of the limbs, or size of the teeth or beak or any measurable trait that is inherited.

The organism you choose must be a real one but the evolutionary change you describe can be real or theoretical.

Remember- evolution take place at the level of the population. Individuals don't evolve, populations evolve.

Describe how the change occurs in terms of the four postulates listed in the book.

You will designate what the population starts out like at time zero and then what it will look like at a later time, as a result of natural selection. Make sure to elucidate the process by which the changes occurred.

What is the selective pressure? Describe why the change might confer more fitness to a particular environment?
The procedure of Natural selection is based on the following four postulates

Postulate 1 - Individual members of a population vary from one another in many respects.

Postulate 2 - At least some of the changes among members of a population are due to characteristics that may be passed from parent to offspring. That is they are heritable or genetic.

Postulate 3 - In each generation several individuals in a population survive as well as reproduce successfully but others don't.

Postulate 4 - The fate of individuals isn't determined by luck. Instead, an individual's likelihood of survival as well as reproduction depends on its characteristics. Individuals with
