I'm not sure it's clear how 'advanced' the last common ancestor was. From the hypothesised date, if it had 'eyes' they probably were simple light sensors:

" But our last common ancestor with the octopus was probably some kind of wormlike creature with eye spots that lived as many as 750 million years ago; " [1]
