More universally, Ghysen [107] argues that vertebrate as well as insect brains have ancient principle sensory and motor circuits with stable functions upon which alterations by gene mutations and embryonic development during evolution are applied to home new functions.

This research addresses the origin and evolution of embryonic development and how modifications of development and developmental processes produce novel features.
These studies suggest that protein regions outside the homeodomain of other Hox proteins might also have some effects on embryonic development and morphological evolution.
We aim to understand the conditions under which the hourglass effect can emerge in a general setting, based on an abstract model for the evolution of embryonic development.
Taking into account the important roles of the Hox genes in animal embryonic development and morphological evolution, we cannot ignore the potential connection between the appearance of UCRs and advent of long gestation periods in placental mammals.
Introduction Modeling the evolution of embryonic development as directed acyclic graph (DAG) in which the nodes correspond to state-transitioning genes and the edges model directed regulatory interactions causing significant activity change at the corresponding stage seems plausible.
Evolution too, like embryonic development, is gradual.
