I guess the next question would be; what survival advantage did light sensitive cells embedded in the brain give to a creature? If they were embedded
in the brain, how would they be exposed to light?
If, although embedded in the brain, they could somehow detect ambient light, what evolutionary advantage would be gained by moving the cells to newly
formed, or should I say mutated eye buds?
For the newly transplanted light sensitive cells to function there would already have to be a fully functioning neural pathway developed to transmit
the signals from the transplanted light sensitive cells back to the brain so they could be interpreted and put to use in order to give the creature an
evolutionary advantage.
I don’t think this is as cut & dry as the article would like to make out.
Everyone seems to have missed this part of the researcher’s statement,
Quite possibly, the human eye has originated from light-sensitive cells in the brain.
Didn't anyone see the "Quite possibly" part? All of this is pure conjecture & supposition.
The fact that there are similar cell types in vertebrates & invertebrates does not automatically prove evolution.
There are still many, many questions that need to be answered.
