How long does it take for a species to evolve? - how long does it take for melonma to spead
Well, let's say one million people moving from a planet where the atmosphere is oxygen, is not enough, breathable (she needs an oxygen mask or something to survive). As for us, I was taught as the first or two years, one might think that the day will come when people can be on this planet, its environment and develop a "breathing adaptation to new people who would be the atmosphere? If so, how long will it take?

You can never adjust oxygen masks in ... The man has the right of the soil protozoa .. But as a person moves into a new planet? how'du and supply of bottled oxygen for the planet? commercial rockets? the earth is running the fuel within hours .. : D
In theory, "oxygen masks" were a person to compensate for the lack of oxygen, essentially artificial selection. Natural selection is very slow, did not immediately change, but long for lungs to a low oxygen environment, far from optimal and can not breathe at all (as suggested by the scenario), then deleted before the time for adaptation. This was the case of terrestrial dinosaurs, whose world has been reversed by a single event that changed all aspects of their lives, so it is impossible to fit within generations, as the event has no restriction imposed on the dying, to their survival and the survival of their children.
A mutation, which they can breathe in the atmosphere resulting from his home planet of new leaves, but only if you selected and a survival advantage over men in a respirator for this mutation.
Transfer speciation is not necessarily dependent. It is likely that some groups in a relatively short period of time, in any case, without any visible or functional, apart from its inability to produce viable offspring with humans on Earth.
To develop your question, "how long it takes for a species to" answer It depends on many factors, there is really no way to generalize.
