A baby songbird could help cure a range of human disorders including autism.

Zebra finch chicks learn to sing in virtually the same way as human babies learn to speak – by copying their elders.

Now researchers have cracked the genetic code of the bird for the first time, identifying more than 800 genes linked to song learning.

Many of their genes are also found in humans.

It means the tiny bird should serve as a valuable model for understanding human learning and memory.

Male baby finches, like human infants, start off by ‘babbling’ before learning to imitate their father’s song.

As they learn in such a predictable way, finches could provide a window into the origins of disorders such as autism, strokes, stuttering and Parkinson’s.

‘Song learning is an excellent paradigm for all types of learning,’ said Chris Ponting, a professor with the Medical Research Council Functional Genomics Unit at University of Oxford, who was involved in the research.

‘There are experiments that can be done that immediately provide information as to what changes occur in neurons (brain cells) upon the learning of a song. The zebra finch genome provides a tool that allows this exploration.’ … Continue reading
