AbstractThe tetrapod double cone is a pair of tightly associated cones called the "principal" and the "accessory" member. It is found in amphibians, reptiles, and birds, as well as monotreme and marsupial mammals but is absent in fish and eutherian mammals. To explore the potential evolutionary origins of the double cone, we analyzed single-cell and -nucleus transcriptomic atlases of photoreceptors from six vertebrate species: zebrafish, chicken, lizard, opossum, ground squirrel, and human.

The evolutionary origins of the vertebrate retina date back more than 500 million years, to a time when the first would-be vertebrates abandoned their previously stationary lifestyles and took to the open water [1,2]. Our early ancestors would have had to rapidly acquire the ability to stabilize in the water, to navigate, and to detect predators and prey—all requirements that in one way or another depend on the detection of visual motion.
