Floods isolate specific townships by cutting off that townships ability to connect to the outside world. Floods are responsible for stopping communication, stopping travel, and making areas hazardous to leave - and to stay in.
The Great Lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes. Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes. Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia. *Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.
No, because a hub is a multi-port repeater, which has no isolation feature.

isolate is a Verb... It is an action.
Certain geographic features isolate a small number of individuals from the rest of the poopulation. Variations that are not common with the larger poopulation may become common with the isolated population so that the variations can create new breeds in the isolated part of the population.Therfore, not only can evolution take place in the crowded areas but also in the isolated part of the population.
The word isolate has its origin in Latin where it is concerned with an island. In Physics one could isolate a region from an incoming wave, such as light, heat, sound, vibration, X-rays and so on. In Chemistry one could isolate a substance on the basis of its optical refraction, or where it was on the acid-base scale. In Biology one could isolate one species or sex from the remainder. There are more, but the general meaning is to separate.
"The teacher wanted to isolate the girl from the rest of the class."
Yes it is possible to isolate DNA from bone.
