Any reference to isolating electrical components, an insulator is the first choice.
Once a single species is physically separated into two or more populations, genetic drift often permanently separates those populations into distinct species no longer able to interbreed, even if they should later again intermingle.
If two or more populations of a single species are separated geographically, whether by mountain ranges, oceans, deserts or even small valleys, they will, over many generations, change to become different from the other populations, assuming there is no physical contact between them. This is due to mutations, which occur every generation, being acted upon by the different environments the populations find themselves in.
Genetic drift occurs in all finite populations. However the effects of drift are more pronounced in smaller populations than in large ones. Meanwhile, even though they are more present in smaller populations, the drifting is more likely to occur in larger populations because of the larger number of different genetic combinations present. Throughout evolution of populations, genetic drifting effects all types of population sizes, though it is more likely in larger populations but more present in smaller populations.
No only men more than females
the populations can change in size because there could be more of the offspring.
2 or more populations living in the same area at the same time is a community.

Speciation is the process by which new biological species arise. It is part of the evolutionary process; how two or more populations of one species, when separated geographically, can gradually change over time in different ways, to become separate species.
