Developmental evolution: torso--a story with different ends?
The Torso pathway patterns the ends of the Drosophila embryo. Now, it has been found to control axis elongation in the short germ insect Tribolium. This result raises the issue of the ancestral function of the Torso pathway and its evolution.
