Scientists have traced the remarkable journey of human eyes back nearly 600 million years to a worm-like ancestor with a single light-sensitive eye atop its head. As this ancient creature became more active, it lost and reinvented its vision system, eventually evolving into the paired eyes we use today—offering fascinating insights into how our sleep cycles developed too.
