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.

Biologists have often wondered what would happen if they could rewind the tape of life’s history and let evolution play out all over again. Would lineages of organisms evolve in radically different ...

When it comes to hard stares and stony gazes, no animal can match the chiton, a small mollusk with eyes made of rock crystal. Now a new study shows just what these strange eyes are capable of.

Diagrams (top) and electron microscope images (bottom) of chiton shells. From left to right: Aesthetes (green) are fount on all chitons, while shell eyes (blue) and eyespots (red) only evolved in a ...
