Hi. Species which evolve in isolation can have unique characteristics. Look at the kangaroo and platypus. Or the species unique to the Hawaiian Islands. Of the tube worms and blond crabs near volcanic vents. Or eyeless cave dwelling insects.

Hi Not being a genius or something but when you are isolated in a certain atmosphere,you have to adapt to the surrounding endowment in order to survive, or you seize to exist. Hence that is how some mutations are created over time. Its the survival thing in nature. I hope this quick answer helps.

Isolation, which can be physical, geographic or behavioural, is a key element in speciation, mainly because mutations do not become swamped. Have a Google for "Ring species"

"Darwin's Middle Road" refers to an essay by S.J.Gould; I don't have it in front of me, so I don't know what "Darwin's Middle Road" actually means.
I know enough of Gould and evolution to know that isolation is important in evolution because it allows for the seperation of breeding populations, which promotes speciation by "branching" of the lineage.
