Why can isolation cause in differences in species and possibly lead to a new species?
I can't explain it to fit for your college thesis but take an example - a two families get stuck on an island. One family has only all fair haired children and one family has only dark haired children. For simplicities sake let's assume all the fair haired children are girls and all the dark haired children are boys. As new generations are born everyone on the island will eventually be mostly dark haired where initially the ratio was 50/50. This is because fair hair is a recessive genetic trait where dark hair is a dominant genetic trait. In order for a person to have the fair hair coloration they have to receive the fair hair gene from both parents and this would be impossible for the first generation of children born to these two families on the island. The second generation COULD however have fair haired children because every one of the first generation carried the recessive gene.
And this is only the most basic generalization.
How is this involved in making a new species? More genes are involved than just genes with hair - for example Japan is a small, and very isolated country (compared to other countries in the world). Japanese people all tend to have similar physical characteristics in facial structure, hair color, and body type. Same for Eskimos, but go to a place like Africa and you see a lot more variety. Some Africans are tall and lanky, some are more heavily built, and Africa has also had a lot of influence from Europe and Middle Asia especially around the Mediterranean and some in South Africa. Although different races of people aren't exactly different species it makes the same point.
And I haven't read it but I think Darwin's Origin of the Species addresses this better than any answer you'll find on Answers.com

Their genes might mutate in different directions, so once their genes do not match up, a new species will be made.

What could cause reproductive isolation?
Any factor that in nature prevents interbreeding between individuals of the same species or of closely related species, for example geographic separation is itself a reproductive isolation because is a factor that prevents interbreeding. -extinction of one species -production of infertile offspring -development of physical differences
What can result from long term isolation?
Long term isolation can cause new species to form if the isolation has been over a very long time.
What factor can cause to two populations to become reproductively isolated?
Geographic isolation, where physical barriers prevent gene flow between populations, can cause reproductive isolation. This can lead to genetic differences accumulating over time, ultimately resulting in the development of separate species.
What factor caused two populations to become reproductively isolated?
It usually is some sort of physical barrier like an large space between islands.
How does isolation relates to speciation?
Isolation such as geological can cause speciation because if one species where divided into two because of geological reasons, they're likely to change their behaviors and physical appearances to match that region.
How can isolation from a species population cause a species to change?
Climatic changes resulted in a drying trend that has continued for the last 10,000 years. The extent to which a geological barrier can effectively isolate a population.
What type of reproductive isolating mechanism is described by a situation in which female fireflies only mate with males who emit light in a particular pattern?
The form of reproductive isolation that is practiced by different species of butterflies is sexual isolation by conduct. This means that the pattern of flashing lights that the male firefly exhibits is specific to that species, and a variation will cause a female firefly to ignore them.
