Gathering vision data for hundreds of vertebrates and invertebrates, biologists have deepened scientists' understanding of animal vision, including the colors they see. The researchers determined ...

First, some basics: Vision depends on light, which comes in a spectrum of wavelengths, ranging from very long to very short. Vertebrate eyes have two kinds of light receptors in the retina at the ...

Scientists reconstructed 500 million years of evolutionary history to reveal which came first: colorful signals or the color ...

Vertebrate vision is made possible by photoreceptor cells in the back of the eye. These cells — called rods and cones — include pigment proteins that detect different types of light and relay ...

Gathering vision data for hundreds of vertebrates and invertebrates, University of Arkansas biologists have deepened scientists’ understanding of animal vision, including the colors they see.

Ancestral circuits for vertebrate color vision emerge at the first retinal synapse. Science Advances , 2021; 7 (42) DOI: 10.1126/sciadv.abj6815 Philipp Bartel, Takeshi Yoshimatsu, Filip K. Janiak ...

Darwin saw the evolution of the vertebrate eye as one of the biggest challenges for his theory. Lamb and colleagues integrate molecular and morphological evidence across different taxa and propose ...

Cornell and Stanford University researchers have solved the three-dimensional structure of a protein complex involved in vertebrate vision at atomic resolution, a finding that has broad implications ...

Vertebrates possess a different style of photoreceptor, which in jawed vertebrates (including ourselves) comes in two varieties: cones for daylight vision and rods for nighttime vision.
