The visual systems of an obscure group of mollusks provide a rare natural example of path-dependent evolution, in which a critical fork in the creatures’ past determined their evolutionary futures.

Researchers say a tiny one-eyed ancestor that lived nearly 600 million years ago may have shaped the evolution of every vertebrate eye, including our own. They also found that its ancient median eye ...

A bizarre, cyclops-like creature from nearly 600 million years ago may hold the key to how your eyes—and even your sleep cycle—evolved. Scientists have discovered that all vertebrates, including ...

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 ...
