The gene that affects how babies pick up language has been identified. If we know more about this gene, can we nurture children and help them learn to better suit their needs and increase their language capabilities?

The importance of FOXP2, and how it affects language.

People have a deep desire to communicate with animals, as is evident from the way they converse with their dogs, enjoy myths about talking animals or devote lifetimes to teaching chimpanzees how to speak. A delicate, if tiny, step has now been taken toward the real thing: the creation of a mouse with a human gene for language.

The FOXP2 gene, a front-runner to explain the evolution of language in humans, may have rewired the brain to allow more advanced learning, according to preliminary research presented at the Society for Neuroscience annual meeting this month. In a recent experiment, Christiane Schreiweis of the Max Planck Institute and colleagues looked at the human version of the gene in mice.

This article explores the role of the human language gene (FOXP2) in mice and how it has affected them cognitively.

Of the 20,000 genes in the human genome, few are more fascinating than FOXP2, a gene that underlies the faculty of human speech. All animals have an FOXP2 gene, but the human version's product differs at just 2 of its 740 units from that of chimpanzees, suggesting that this tiny evolutionary fix may hold the key to why people can speak and chimps cannot.

Language in humans has evolved culturally rather than genetically, according to a new study. By modeling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language. Professor Nick Chater, University College London Cognitive, Perceptual and Brain Sciences, says: "...although we have appear to have a genetic predisposition towards language, human language has evolved far more quickly than our genes could keep up with, suggesting that language is shaped and driven by culture rather than biology. The linguistic environment is continually changing; indeed, linguistic change is vastly more rapid than genetic change. "

Do genes cause a preferance for tonal or non tonal languages? Possibly. Researchers have discovered ASPM and microcephalin, two genes that are linked to brain growth, may cause a preference for tonal languages.

Scientists have implemented the human gene deemed responsible for our ability to communicate into a strain of mice. This could be the first step towards having talking animals someday, and it also allows us to understand more about how genetics affect language.

"Birds learn to sing their songs and babies learn to make the sounds of their language in the same way.... Furthermore, both birds and humans go through a period [critical period] when learning is best accomplished... the brain architecture supporting babbling and birdsong is similar...the same mutated gene, FOXP2, is implicated in both [birdsong and speech]."

What a find! He talks about so many of the things we've touched on, and the fact that he titles his post "Birds R Us" is just too funny. :) I like that he provides the links to the original research, too.

Not about linguistics, but of general interest to students. Talks about genetic basis for test anxiety--and under which conditions it is advantageous. This article is long but gets more interesting the further you read.

Recent advances in our understanding of the genetic basis of human cognition (thinking) have enabled scientists at the Max Planck Institutes for Psycholinguistics, Evolutionary Anthropology, and Human Cognitive and Brain Sciences. to better understand 3 areas of language: 1. Language processing: The human genome directs the organization of the human brain and some peripheral organs that are prerequisites for the language system, and is probably responsible for the significant differences in language skills between individuals. At the extremes are people with extraordinary gifts for learning many languages and undertaking simultaneous interpretation, and people with severe congenital speech disorders. 2. Language and populations: Genetic methods have revolutionized research into many aspects of languages, including the tracing of their origins. 3. Structural differences: While languages are not inborn, certain genetic predispositions in a genetically similar population may favour the emergence of languages with particular structural characteristics - an example thereof is the distinction between languages that are tonal (such as Chinese) and non-tonal (such as German).

"Did Neanderthals sing? Is there a 'music gene'? Two scientists debate whether our capacity to make and enjoy songs comes from biological evolution or from the advent of civilization. Music is everywhere, but it remains an evolutionary enigma."

An article which describes the background and ideas behind Mark Pagel's book, "Wired for Culture" and how language is intertwined in our society and cultural background.

Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, summarizes a decade's worth of research in this article. He concludes that laughter is primarily a social vocalization that binds people together. It is a hidden language that we all speak. It is not a learned group reaction but an instinctive behavior programmed by our genes. Laughter bonds us through humor and play. He also explores gender differences in regard to the role of laughter in communication, also laughter as a tool in romance/pair-bonding.
