Q: What fascinates you about the eye? A: The eye is an absolutely fascinating organ because it's an organ of extreme perfection, as Darwin has called it. We are able to adjust the focus, we are able ...

Convergent origins of new mechanisms to supply oxygen to the retina were directly linked to concurrent enhancements in the functional anatomy of the eye. In his "On the Origin of Species", Darwin used ...

One of the biggest mysteries of evolution is how species first developed complex vision. Jellyfish are helping scientists solve this puzzle, as the group has independently evolved eyes at least nine ...

Why did humans evolve the eyes we have today? While scientists can't go back in time to study the environmental pressures that shaped the evolution of the diverse vision systems that exist in nature, ...

Growing up in Sweden, author J. Arvid Ågren was taught British evolutionary biologist Richard Dawkins' selfish gene theory, which was commonly taught in Europe. When Ågren arrived in North America for ...

The standing dogma of eye evolution is challenged with the discovery of an invertebrate that sees light like vertebrates do, rather than like their more closely related cousins, according to a study ...

The fascinating compound eyes of insects consist of hundreds of individual eyes known as 'facets'. In the course of evolution, an enormous variety of sizes and shapes has emerged, often adaptations to ...
