Uberon Homology note : (...) we reach the inescapable conclusion that the last common ancestor of jawless
and jawed vertebrates already possessed an eye that was comparable to that of extant
lampreys and gnathostomes. Accordingly, a vertebrate camera-like eye must have been
present by the time that lampreys and gnathostomes diverged, around 500 Mya (reference
1); Although the eye varies greatly in adaptative details among vertebrates, its basic
structure is the same in all. The human eye is representative of the design typical
for a tetrapod. (...) A watery aqueous humor fills the spaces in the eye in front
of the lens (...) (reference 2).[well established][VHOG];
Uberon Structure note : synthesized by the lens epithelium and its main components are Type IV collagen and
sulfated glycosaminoglycans (GAGs). [Wikipedia:Capsule_of_lens;
