Answer:
Reproducibility is important because it is the only thing that an investigator can guarantee about a study. Contrary to what most press releases would have you believe, an investigator cannot guarantee that the claims made in a study are correct (unless they are purely descriptive) So reproducibility is important not because it ensures that the results are correct, but rather because it ensures transparency and gives us confidence in understanding exactly what was done.

Explanation:
The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.
Borders are still guarded zealously and fought for - via wars when required and when not required in equal measure. I see nations fighting
over water that preciously scarce resource of the future. I see that terrorists still abound - the Osama Bin Laden types still roam the Earth terrorizing countries and peoples with newer weapons and newer methods of instilling terror. I see that the United States is no longer the sole superpower of the world -- the most powerful country on Earth. I see the most powerful countries dominating the world as being China, India, Brazil and Russia in that order. I see that China and India have become the equivalent of the US and the erstwhile Soviet Union - fighting another Cold War between them and competing for resources and influence around the world.
