Among geographers and linguists a prevalent, though controversial, theory posits that the rise of transformed the distribution of the world s languages and language families.

farming populations

Explanation:

As we know, there are thousands of languages spread across our planet. Many scientists claim that these languages, or at least most of them, originated from a single language, even though these languages are now totally different from one another.

Languages are believed to have a common origin, but what is that origin? Well, it is not known, although there are several theories that try to explain this origin and end up contradicting themselves at one time or another. What is known is that this spread of different languages followed (and probably arose) through agriculture and, mainly, the spread of different agricultural populations.

Agriculture and spread in farming population

Explanation: The argument above is based on the farming/language dispersal principle which argues that the spread and dispersion of most of the world's popular languages was aided with the spread of agriculture.

Though the argument between linguist and geographers is a strong case and various hypothesis offer contradictory views. However, the diverse number of languages being spoken all over the world, emanated from a few world major languages and it's dispersion all over the world was largely due to the spread of agriculture across various geographical locations.
