Do you know…? 

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.

By about 3000 BC Semitic languages are spoken over a large tract of desert territory from southern Arabia to the north of Syria.
