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 ...

This essay was launched by reading an almost unintelligible (to me) scientific paper about chiton eyes. Nevertheless, that paper led to others, and here I have summarized some of the related natural ...

There is considerable interest in understanding how vision and image-forming eyes evolved, and scientists tend to take it for granted that most vertebrates have two eyes. Writing in Nature, Lei et al.

The preservation of fossils of some of the oldest known vertebrates is so impressive that palaeontologists can not only count their eyes, but determine how they worked. The findings demonstrate that ...

You’d probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it’s ...

Even Charles Darwin was puzzled by the evolution of the vertebrate eye. New research suggests that it traces back to a cyclopean invertebrate with a single eye atop the head. By Carl Zimmer Look at ...

There is a tiny cyclops among your oldest ancestors, and humans share these remarkable ancestral roots with all other vertebrates. Researchers from Lund University and University of Sussex have found ...

One of the most common adaptations seen in the animal kingdom is vision. Nearly 96% of all animals have some kind of eyes and they've proven so evolutionary advantageous that they've evolved multiple ...
