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 ...
