Researchers feel they have found what could be the ancient language that links all languages across Eurasia from the end of the last Ice Age. According to the Bible all mankind once spoke the same language.
“And the whole earth was of one language and of one speech.
And it came to pass, as they journeyed east, that they found a plain in the land of Shinar; and they dwelt there.
And they said one to another: 'Come, let us make brick, and burn them thoroughly.
And they had brick for stone, and slime had they for mortar.
And they said: 'Come, let us build us a city, and a tower, with its top in heaven, and let us make us a name; lest we be scattered abroad upon the face of the whole earth.
And the LORD came down to see the city and the tower, which the children of men built.
And the LORD said: 'Behold, they are one people, and they have all one language; and this is what they begin to do; and now nothing will be withholden from them, which they purpose to do.
Come, let us go down, and there confound their language, that they may not understand one another's speech.
So the LORD scattered them abroad from thence upon the face of all the earth; and they left off to build the city.
Therefore was the name of it called Babel; because the LORD did there confound the language of all the earth; and from thence did the LORD scatter them abroad upon the face of all the earth.”
These bible verses explain how and why the confusion of language takes place. Today there is a wide variation in human languages. This was not always so. At one point in human history the bible says there was a common language.
According to Proceedings of the National Academy of Sciences April 2013 report, several different language groups come from a common original source. Some words even maintained the same meaning and similar sound to their original form. Word reconstruction for dead languages is a difficult task. Words morph and evolve rapidly. Most have a 50-50 chance of being replaced every 2,000 to 4,000 years.
Researchers discovered a number of words, such as "this," "I," "give," "mother," "hand," "black," "ashes," "old," "man," "fire" cropped up in a similar form in at least four of the seven language families studied. These words were traced them back to 15,000 years, which is the time the glaciers were melting. This event gave humankind the impetus to spread out around the world and for languages to begin to diverge.
Would an Ice Age man understand us today? It depends on the words. There are “fossil” words that have escaped considerable alteration over the ages. Through these words, researchers say they have identified an ancient language.
Some of the common words discovered were, "this," "I," "give," "mother," "hand," "black," "ashes," "old," "man," and "fire".
If you were to say to a person living in the ice age, "Black ashes?”, “Who is this old man?”, “Mother, I hear fire!", there is a pretty good chance they would understand you.
