Last week a paper was published in PLoS-ONE suggesting a relation between AVPR1A-Haplotypes and musical creativity. A group of Finish researchers analyzed 19 families with a total of 343 family members on their musical aptitude —using the Seashore test and a test developed by one of the authors— and their DNA profiles. They were able to show an association between these and related genes and levels of musical creativity. The research contrasts earlier research with twins that suggested no such relation (e.g., Coon & Carey, 1989). The authors propose the interesting hypothesis that music perception and creativity in music are linked to the same phenotypic spectrum of human cognitive social skills, like human bonding and altruism, both associated with AVPR1A. Music as a form of ‘extreme’ bonding behavior...
It was just a matter of time for such a study to emerge. Still, the results of this study are merely correlational. I like to think of the capacity for music as shared instead of being special, and a result of complex nature and nurture interactions.
