The model confirms experiments showing how numerous factors determine body pattern formation, and the critical role nerve fibers play in determining polarity in regeneration.

Meanwhile, Wnts that are critical for determining polarity and guidance along the A/P axis are also involved in setting up polarity along the D/V axis.

When ontogenetic transformations are viewed as characters, there can be no ontogenetic method for determining evolutionary character polarity; however, the comparative phylogenetic method properly ...
