Recently in my biology class, we have made transverse cuts in planaria 
and are know observing them regenerate. I'm fascinated by  The 
Anterior-Posterior Gradient. Any theories on why the regeneration is less 
complete as the cut is made further from the head? Has this phenomena 
ever been quantified?
