What was the pre-Babel language and what can be said about the mechanism used to confuse the languages? The Tower of Babel episode in human history is known to many. This can be found in Genesis 11. As we know, it resulted in the languages of mankind becoming confused.

Question: Are there opinions, speculations, conjectures, or a consensus anywhere on what the pre-Babel language was? Are there linguistic clues in modern languages spoken today that can shed light on this topic? We do not really know the exact mechanism used by God to confuse the languages. Is it possible that the mechanism is something amenable to investigation from the fields of neuroscience/computer science?
It is held by some to be the Adamic language, properly named, though Midrash and Talmud say it was Hebrew. See wikipedia on the Confusion of Tongues.
