Abstract

We reach the conclusion that posterior prevalence, a collinear property considered important for Hox complex function is so far unique, in a global form, to vertebrates. Why is this? We suspect this is because posterior prevalence is explicitly connected to the vertebrate form of Hox temporal collinearity- which is central to axial patterning.
