The master gland of domestication?
When we think of Charles Darwin and his theory of natural selection, the mind conjures images of exotic voyages to distant lands. However, in reality, Darwin's theory was more heavily influenced by his observations on the process of domestication, which he made in his own backyard. The evolution of domestic animals still fascinates biologists, and in this episode of the Heredity Podcast Dr Amir Fallahshahroudi discusses his recent research on the genetic basis of domestication in the chicken. This work has focused in on the pattern of gene expression in the pituitary gland, a small organ that lies between the brain and the rest of the body: could this 'master gland' of hormone production also be controlling the development of the 'domestic phenotype'? Tune in and find out.
