Assuming these two groups of organisms (not any particular species) are COMPLETELY seperated, approximately how long until they develop into seperate species? When I say "seperate species," I mean that if an individual from each population were to mate, conceiving offspring would either be impossible, or the offspring would at least be disabled or infertile.

If the environments in which they live are similar (two tropical rain forests seperated by mountains or some such obstacle), will the development of seperate species take longer? What if the environments are different? (Forest and tundra?)

Suppose you are looking at a sample of pond water, and you see a single-celled organism swimming in the water. It's green, and moves quickly. There's a clear picture of a nucleus, but you can't see any other organelles with your compound light microscope. In what kingdom does this organism belong? What other characteristics do you expect this organism to have?

say that alaska and antartica which were once covered in snow, now has a different face and appearance. In other words, since different physical being evolved from another, or evolved to another state or form; will we do the same? If so, when do you think the evolution of mankind will take place, if the evolution of the earth is already taking place? Do you think that it will happen this lifetime? keep in mind all of the occurences that has anything to do with evolutionary change.

I ask because when scientists ponder whether there is life elsewhere in the universe what exactly is the criterion they use? I mean, can't all things, even down to the atom, be considered a form of life - albeit a simple one?
