Abstract:
The Drosophila bicoid gene is well known for encoding a protein that forms a morphogenetic gradient with a key role in anterior patterning of the fruitfly embryo. Recent results suggest the evolution of bicoid might have involved dramatic changes in function - essentially the invention of a new regulatory protein.
