To the untutored eye, the divergence does not make sense.
Therefore, genes expressed in the cephalopod eye after divergence from the common molluscan ancestor could be involved in eye evolution through association with the acquisition of new structural components.
Previous studies concerning the dynamics of convergence and divergence eye movements have produced varied, sometimes contradictory, results: most studies report that convergence is considerably faster than divergence, but opposite results have also been reported.
The first group consists of genes that commonly exist in animals, but whose expression level has been changed through the structural changes of the eyes after the divergence of the cephalopods.
[ 32] investigate the existence of local molecular clocks during the radiation of mammals with an eye to reconciling molecular divergence dates with fossil evidence.
In contrast, in the experiment with TMS of the PPC latencies for TMS trials increased relative to no-TMS trials for almost all eye movements (isolated saccades, convergence, divergence, and for saccade and divergence components of combined eye movements).
We found that although participants from both groups responded to object changes in the pictures, there was still evidence for cultural divergence in eye-movements.
When correcting for baseline differences between the Aflibercept (11 eyes) and Ranibizumab (16 eyes) group, there was neither divergence in visual acuity (−0.97 letters (95%% CI. −6.06-4.12); p = 0.709), nor a significant difference in the reduction of CFT (−25.16 μm, 95%% CI; (−78.01-27.68); p = 0.351) between the two groups 1 year after treatment initiation.
If the evolutionary divergence of both eye types dates back to the first euarthropods, more than 500 mya [ 25], was there no need for spectral specialization earlier?
First, we studied some of these divergence specific matrices by eye.
