Uberon definition : A structure created during embryogenesis when the lateral mesoderm splits into two
layers - the outer (or somatic) layer becomes applied to the inner surface of the
ectoderm, and with it forms the somatopleure.[WP].;
Uberon Development note : Gives rise to the paired appendages in jawed vertebrates. a persistent somatopleure
through the redistribution and expansion of the lateral plate mesoderm is a synapomorphy
for gnathostomes and a critical step in generating a novel developmental module with
dramatic evolutionary potentia (Tulenko et al. 2012) http://burkelab.research.wesleyan.edu/current-projects/lamprey/;
