Two countries that share an island
New Hampshire and Georgia
this is cooperation.
Africa and Asia
Europe and Asia share a single landmass.
Genetic drift
a community... biotch
When the two populations can no longer interbreed.
i dont no this im the one who asked it
they sometimes work together or either battle each other for the better job
Two populations have evolved into two species when the populations can no longer interbreed.Are you answering a question from the Holt Science & Technology: Life Science textbook? Because these questions are my homework. :P

That there is no difference between the means for the two populations.
Sure. It is very useful to connect two or three computers together, if you happen to have them. That way, you can share files, share a printer, and share the Internet connection, among others.
If two sub-populations of a species become reproductively isolated, it means that adaptation or genetic drift can make the two populations diverge genetically. If, as a result of this divergence, upon reintroduction, members of the two sub-populations no longer reproduce successfully, the two sub-populations have become different species.
I found the answer to my own question. If the first six digits of a stock's CUSIP number are the same as another then they are the same company but different share classes. So if you can download a list of stock tickers with their CUSIP's and sort in a spreadsheet you should be able to identify the majority of dual share class stocks. However, if anyone knows an easier way please share. Thanks!
