Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
Repeated evolution of eye regression in subterranean mammals helps identify genes and regulatory elements involved in visual perception and development of the eye, and predicts candidate sequences with a potential role in ocular disorders.
Signals conveyed from two different senses from a given point in space converge onto the same neurons of the optic tectum that trigger the gaze-control-system, and at the same time inhibit other parts of the tectal motor map.
Neuronal junctophilins 3 and 4 similarly recruit and functionally modify P/Q and N-type calcium channels, but differentially recruit the three ryanodine receptor isoforms to endoplasmic reticulum-plasma membrane junctions.
When real ants confront the classical 'Ant-in-a-labyrinth' physics problem where a random walker traverses a percolated environment, they employ active extended sensing and collective cognition to outperform passive physical solutions.
