Ray,

Thanks for all the great anonymous postings. Regarding musical aptitude genes, I found these two items from the World Science site recently. I wasn't altogether certain of their scientific foundation, not knowing that much about genetics. In the first piece the arginine vasopressin receptor 1A is also referred to as a gene--which sounded weird to me because I thought genes only determined the cellular characteristics, which would direct the cell to devise the receptor, but an antidiuretic hormone receptor? Regardless, as one reads the second piece, the research speaks to the genetic role of music in order to develop language, communication, and brain/body health/connections in general.

*Peo­ple's in­ter­est in mu­sic may be re­lat­ed to a gene that has al­so been found to be as­so­ci­at­ed with mu­sical ap­ti­tude -- and sing­ing in birds, a new study re­ports.

The find­ings al­so add to grow­ing ev­i­dence that mu­sic draws on a sys­tem of brain wir­ing that more gen­erally pro­motes at­tach­ment be­hav­iors, ac­cord­ing to the re­search­ers, Ir­ma Järvelä of the Uni­vers­ity of Hel­sin­ki and col­leagues.

"The re­sults sug­gest that will­ing­ness to lis­ten to mu­sic is re­lat­ed to neuro­bi­o­log­i­cal path­ways af­fect­ing so­cial af­filia­t­ion and com­mu­nica­t­ion," they wrote, re­port­ing their find­ings in the Feb. 10 ad­vance on­line edi­tion of the /Jour­nal of Hu­man Ge­net­ics/.

Mu­sic is part of all known cul­tures, Järvelä and col­league not­ed. Si­m­i­lar­i­ties be­tween hu­man and an­i­mal song have been de­tected, they ar­gue: both con­tain a mes­sage, and an in­ten­tion that re­flects emo­tion­al state and is often in­ter­preted cor­rectly even among dif­fer­ent spe­cies. Sev­er­al mu­sic-re­lat­ed be­hav­iors al­so pro­mote at­tach­ment, they added: lul­la­bies are meant to bond a par­ent with an in­fant, and sing­ing or play­ing mu­sic to­geth­er is based on team­work and may en­hance group co­he­sion.

The re­search­ers col­lect­ed da­ta on 437 Finns from 31 fam­i­lies, aged eight to 93, with mu­sical education ranging from none to ex­ten­sive. The par­ti­ci­pants were sur­veyed about their mu­sic lis­tening habits and tested in three ways for mu­sical ap­ti­tude. Their DNA was al­so an­a­lyzed.

Will­ing­ness to lis­ten to mu­sic was as­so­ci­at­ed with vari­ants in a gene called ar­gi­nine vas­o­pres­sin re­cep­tor 1A, the invest­i­gators found. The gene serves to help transmit a hormone called ar­gi­nine vas­o­pres­sin in the brain.

The Hel­sin­ki sci­en­tists had al­so found as­socia­t­ion be­tween the same gene and mu­sical ap­ti­tude in find­ings re­ported in the May 2009 is­sue of the re­search jour­nal /PLoS One/. And the ver­sion of that chem­i­cal known in birds and oth­er spe­cies was found to in­crease dawn sing­ing in male field spar­rows in a study de­scribed in the Au­gust 1998 edi­tion of the jour­nal /Hor­mones and Be­hav­ior/. Dutch re­search de­tailed in the /Eu­ro­pe­an Jour­nal of Phar­ma­col­o­gy/ for last Jan­u­ary al­so found that ma­ni­pu­lat­ing lev­els of the sub­stance, called va­so­tocin, in song­birds "pro­motes ac­qui­si­tion of a sta­ble ster­e­o­typed song pat­tern." Va­so­tocin al­so in­flu­ences breed­ing in lizards and fish, Järvelä and col­leagues said.

The re­sults "pro­vide a mo­lec­u­lar ev­i­dence of sound or mu­sic's role in so­cial com­mu­nica­t­ion, and are pro­vid­ing tools for fur­ther stud­ies on gene-culture ev­o­lu­tion in mu­sic," the uni­vers­ity said in a sum­mary of the re­search re­leased on Feb. 24.**

*Musical genes may be coming to light*

April 30, 2008
Special to World Science <http://www.world-science.net>

*Sci­en­tists say they've found ap­prox­i­mate loca­t­ions in our ge­nome where genes af­fect­ing mu­si­cal tal­ent may lie, the re­sults of the first, small study to sys­tem­at­ic­ally seek these out.

The find­ings suggest mu­si­cal abil­ity is partly ge­net­ic and may share ev­o­lu­tion­ary roots with lan­guage, ac­cord­ing to the re­search­ers, who stud­ied Finn­ish fam­i­lies.

**he work may al­so be a step to­ward re­veal­ing "the role of mu­sic in hu­man brain func­tion, hu­man ev­o­lu­tion and its rela­t­ion­ship to lan­guage," they wrote, though they added it will take larg­er fol­low­up stud­ies to clar­i­fy this.

The study of 234 Finns from 15 fam­i­lies---all with at least some mu­sicians---was pub­lished in the April 18 ad­vance on­line is­sue of the/Jour­nal of Med­i­cal Ge­net­ics/.

Kris­ti­ina Pul­li of the Uni­ver­s­ity of Hel­sin­ki and col­leagues tested the par­ti­ci­pants us­ing so-called link­age anal­y­ses, a type of probe de­signed to tie par­tic­u­lar traits to spe­cif­ic ar­eas of the ge­nome.

The anal­y­sis works by ex­am­in­ing wheth­er a giv­en trait of­ten oc­curs in peo­ple who al­so have a dis­tinct bit of ge­net­ic code at a known ge­nomic site. If so, it sug­gests this "mark­er" code is phys­ic­ally near a gene for that trait; oth­er­wise, gene-scram­b­l­ing pro­cesses in­volved in re­pro­duc­tion would tend to en­sure the two things stopped oc­cur­ring to­gether.

As part of the re­search, each par­ti­ci­pant al­so took three tests of mu­si­cal ap­ti­tude.

The re­search­ers re­ported find­ing "sig­nif­i­cant ev­i­dence" for an as­socia­t­ion be­tween that abil­ity and a small re­gion of Chro­mo­some 4. Hu­man genes lie on about two doz­en dis­tinct chro­mo­somes, most num­bered by size from big­gest to small­est.

The patch of DNA in ques­tion en­com­passed about 50 genes, Pul­li and col­leagues wrote. Of par­tic­u­lar in­ter­est with­in these, they added, was one known as netrin re­cep­tor UNC5C pre­cur­sor. This gene, they wrote, in­ter­acts with mo­le­cules that gov­ern the de­vel­op­ment of brain cells and their intercon­nec­tions. Mu­ta­tions in the gene are al­so in­di­rectly linked to de­fects in time and pitch pro­cess­ing, they added.

There's al­so ev­i­dence such mutations may be con­nect­ed to the lan­guage dys­func­tion dys­lex­ia, sug­gest­ing pos­si­ble con­nec­tions be­tween mu­sic and lan­guage, the team pro­posed. In­ter­est­ing­ly, they added, of the three mu­si­cal tests they used, the one with the strongest ap­par­ent link to the gene re­gion is al­so pre­dic­tive of dys­lex­ia, which im­pairs read­ing and spell­ing abil­ity.

The team al­so re­ported two oth­er snip­pets of the ge­nome pos­sibly but more weakly linked to mu­si­cal ap­ti­tude, on Chro­mo­somes 8 and 18---the lat­ter at a re­gion al­so linked to dys­lex­ia.

In find­ings that ech­oed Pul­li's some­what, a sep­a­rate group re­ported in the April 16 ad­vance on­line is­sue of the /Jour­nal of Cog­ni­tive Neu­ro­sci­ence/ that chil­dren with lan­guage syn­tax deficits al­so have mu­si­cal dif­fi­cul­ties .

Sci­en­tists have long sus­pected mu­sic might have ge­net­ic roots. "Mu­sic is an an­cient and un­iver­sal fea­ture across all hu­man so­ci­eties," not­ed Pul­li and col­leagues. The not-un­com­mon ap­pear­ance of fam­i­lies of mu­si­cians, such as the clan that fa­mously spawned J.S. Bach in 1685, al­so sug­gest a ge­net­ic basis, the re­search­ers added---though oth­er fac­tors could ex­plain that phe­nom­e­non.

Their stu­dy, they con­tin­ued, while too small to be de­fin­i­tive, is "a start­ing point for fur­ther map­ping, isola­t­ion, and char­ac­ter­iz­a­tion of genes that pre­dis­pose to mu­si­cal ap­ti­tude."**

Think of the ensembles that the mining corporations funded in England and Nova Scotia. All to build community and coherence. It doesn't work unless it's long term and carries over generations. It took 300 years for the great works of the 19^th century to evolve in Europe. When they began to let that go, they slipped into war. Njinsky couldn't believe what they had let happen. It so depressed him that he ended his life in an insane asylum. The greatest artist of his day. To get Bach you needed seven generations of Bach family musicians. It's complex.
