Half a billion years ago, in the shallow seas of what is now southern China, creatures no larger than a thumb were navigating a dangerous world with four fully functional eyes — two facing sideways, two pointing skyward. Chinese researchers have now confirmed, through molecular and structural analysis of fossilized remains, that these primitive jawless fish possessed a visual sophistication that challenges long-held assumptions about early vertebrate life. Their discovery reminds us that complexity does not always build forward — sometimes it transforms, trading one kind of seeing for another,
