HISTORY OF LANGUAGES

Words on the brain: from 1 million years ago?
All social animals communicate with each other, from bees and ants to whales and apes, but only humans have developed a language which is more than a set of prearranged signals.
Our speech even differs in a physical way from the communication of other animals. It comes from a cortical speech centre which does not respond instinctively, but organises sound and meaning on a rational basis. This section of the brain is unique to humans.
  When and how the special talent of language developed is impossible to say. But it is generally assumed that its evolution must have been a long process.
Our ancestors were probably speaking a million years ago, but with a slower delivery, a smaller vocabulary and above all a simpler grammar than we are accustomed to.
  Origins of language
The origins of human language will perhaps remain for ever obscure. By contrast the origin of individual languages has been the subject of very precise study over the past two centuries.
There are about 5000 languages spoken in the world today (a third of them in Africa), but scholars group them together into relatively few families - probably less than twenty. Languages are linked to each other by shared words or sounds or grammatical constructions. The theory is that the members of each linguistic group have descended from one language, a common ancestor. In many cases that original language is judged by the experts to have been spoken in surprisingly recent times - as little as a few thousand years ago.
Linguistic groups: from 3000 BC
The most widespread group of languages today is the Indo-European, spoken by half the world's population. This entire group, ranging from Hindi and Persian to Norwegian and English, is believed to descend from the language of a tribe of nomads roaming the plains of eastern Europe and western Asia (in modern terms centring on the Ukraine) as recently as about 3000 BC.
From about 2000 BC people speaking Indo-European languages begin to spread through Europe, eventually reaching the Atlantic coast and the northern shores of the Mediterranean. They also penetrate far into Asia - occupying the Iranian plateau and much of India.
  Another linguistic group, of significance in the early history of west Asia and still of great importance today, is the Semitic family of languages. These also are believed to derive from the language of just one tribal group, possibly nomads in southern Arabia.
By about 3000 BC Semitic languages are spoken over a large tract of desert territory from southern Arabia to the north of Syria. Several Semitic peoples play a prominent part in the early civilization of the region, from the Babylonians and Assyrians to the Hebrews and Phoenicians. And one Semitic language, Aramaic, becomes for a while the Lingua franca of the Middle East.
  Language and race
A shared linguistic family does not imply any racial link, though in modern times this distinction has often been blurred. Within

Spitting in public -- If you're on the street, then you're probably not playing baseball. Tuberculosis may not be an epidemic anymore, but spitting is still gross -- its a bodily fluid.

  Cursing -- We have a lot of saltwater in Hampton Roads, but that does not make everyone a sailor.

  Lecturing -- Not to nag, but people usually go to church when they want to hear a sermon. Of course, this list may border on being a form of lecture.

Not washing hands -- People don't necessarily need to come into contact with everything everyone else has come into contact with. When you're at the store, think about how many people have touched the same thing you just picked up.
