VOCAL - Genomics and quantitative genetics of vocal learning in birds

The main goal of this project is to map individual genes implicated in vocal learning differences among breeds of the canary bird. We propose an integrative approach grounded on an appropriate model system, which combines the power of genetic mapping approaches with comparative and functional genomics. We will employ state of the art approaches and carry out four main tasks:

(1) linkage mapping for studying the genetic basis and architecture of vocal behavior in canaries;

(2) population genomics using whole genome resequencing;

(3) functional genomics for experimental validation and identification of specific genes/mutations;

(4) molecular evolutionary analysis to assess evidence for convergence at the protein and regulatory levels of genes implicated in vocal learning.

This innovative project represents an excellent opportunity to shed light on the evolution of complex vocal behaviors, including the fascinating diversification of song in birds and the emergence of language in humans.
