If humans are genetically related to chimps, why did our brains develop the innate ability for language and speech while theirs did not? Scientists suspect that part of the answer to the mystery lies in a gene called FOXP2. When mutated, FOXP2 can disrupt speech and language in humans. Now, a UCLA/Emory study reveals major differences between how the human and chimp versions of FOXP2 work, perhaps explaining why language is unique to humans. Published Nov. 11 in the online edition of the...

Scientists of the German Mouse Clinic at Helmholtz Zentrum Mnchen have generated and analyzed a mouse model in which parts of the human Foxp2 gene were introduced. Foxp2 is known to be a key gene for language. Since the human and chimpanzee lineages diverged, only minimal genetic alterations have occurred, even with reference to the mouse: The alterations, as scientists surmised, are closely associated with speech and language ability. However, proof on a functional level has been lacking...

German researchers have given mice the so-called "language gene" in an effort to understand the evolution of language. While the genetically-altered mice can't speak, they squeak differently and their brain circuits are measurably different "“ offering insight into how the gene works and how it evolved. The language gene, FOXP2, was first identified in 1998 when researchers discovered that members of a large family with a speech impediment had defective copies of the gene. The gene is...

New research suggests different types of language disorders may be genetically linked. Variations of a gene called FOXP2 have been shown in previous research to cause a rare speech and language disorder, and mutations that affect the gene are associated with difficulties in learning and speaking. A new study shows a gene targeted by FOXP2 is associated with language impairment caused by several different disorders. Researchers evaluated the speaking ability of families with a certain type of...

CAMBRIDGE, Mass. "” The evolution of human speech was far more complex than is implied by some recent attempts to link it to a specific gene, says Robert Berwick, professor of computational linguistics at MIT. Berwick will describe his ideas about language in a session at the annual meeting of the American Association for the Advancement of Science on Sunday, Feb. 17. The session is called "Mind of a Toolmaker," and explores the use of evolutionary research in understanding human...

WASHINGTON, Wed., Aug. 31, 2005 "“ The first comprehensive comparison of the genetic blueprints of humans and chimpanzees shows our closest living relatives share perfect identity with 96 percent of our DNA sequence, an international research consortium reported today. In a paper published in the Sept. 1 issue of the journal Nature, the Chimpanzee Sequencing and Analysis Consortium, which is supported in part by the National Human Genome Research Institute (NHGRI), one of the National...

The Foxp2 gene plays an essential role in the development of social communication, according to a study led by researchers at Mount Sinai School of Medicine. The association between Foxp2 and language was first identified in a family in which half the members had severe speech and grammar impairments. Studies showed that all the affected family members had a mutation in the Foxp2 gene. The gene is found on a region of chromosome 7 that is linked to other disorders that affect speech,...
