World’s languages traced back to single African mother tongue: scientists.

New Zealand researchers have traced every human language — from English to Mandarin — back to an ancestral language spoken in Africa 50,000 to 70,000 years ago.

Scientists say they have traced the world’s 6,000 modern languages — from English to Mandarin — back to a single “mother tongue,” an ancestral language spoken in Africa 50,000 to 70,000 years ago.

New research, published in the journal Science, suggests this single ancient language resulted in human civilization — a Diaspora — as well as advances in art and hunting tool technology, and laid the groundwork for all the world’s cultures.

The research, by Quentin Atkinson from the University of Auckland in New Zealand, also found that speech evolved far earlier than previously thought. And the findings implied, though did not prove, that modern language originated only once, an issue of controversy among linguists, according to the New York Times.

Before Atkinson came up with the evidence for a single African origin of language, some scientists had argued that language evolved independently in different parts of the world.

Atkinson found that the first populations migrating from Africa laid the groundwork for all the world’s cultures by taking their single language with them. “It was the catalyst that spurred the human expansion that we all are a product of,” Atkinson said, the Wall Street Journal reported.

Atkinson traced the number distinct sounds, or phonemes — consonants, vowels and tones — in 504 world languages, finding compelling evidence that they can be traced back to a long-forgotten dialect spoken by our Stone Age ancestors, according to the Daily Mail.

Atkinson also hypothesized that languages with the most sounds would be the oldest, while those spoken by smaller breakaway groups would utilize fewer sounds as variation and complexity diminished.

The study found that some of the click-using languages of Africa have more than 100 phonemes, or sounds, whereas Hawaiian, toward the far end of the human migration route out of Africa, has only 13, the Times reported. English has about 45 phonemes.

The phoneme pattern mirrors the pattern of human genetic diversity as humans spread across the globe from sub-Saharan Africa around 70,000 years ago.

The wars in Iraq and Afghanistan represent only a fraction of the billions spent to battle terrorists since Sept. 11, 2001. Lawmakers in Washington have shelled out some $34 billion over the last 10 years to state and local law enforcement. Our new map shows how much each state has raked in by grant program and fiscal year, based on data obtained from the Department of Homeland Security.

Wall Street’s Repeat Violations, Despite Repeated Promises

Many big Wall Street firms have settled fraud cases brought by the government with a promise to never violate the same law. But an analysis of Securities and Exchange Commission documents by The New York Times found that since 1996, there have been at least 51 repeat violations by those firms. Bank of America and Citigroup have each had six repeat violations, while Merrill Lynch and UBS have each had five.

God, I wish I could break the law with impunity as long as I (falsely) promised to never ever do it again.
