Scientists say humans share ancestry with a tiny one eyed creature from 600 million years ago, and remnants of its “cyclops” eye may still exist deep inside our brains.

Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a new study. The organoids spontaneously developed ...
