We Never Know

Well that's a little freaky.
Scientists Grew 'Mini Brains' From Stem Cells. Then, The Brains Sort-of Developed Eyes.
"Mini brains grown in a lab from stem cells spontaneously developed rudimentary eye structures, scientists reported in a fascinating paper in 2021.
On tiny, human-derived brain organoids grown in dishes, two bilaterally symmetrical optic cups were seen to grow, mirroring the development of eye structures in human embryos.
This incredible result will help us to better understand the process of eye differentiation and development, as well as eye diseases.
Our work highlights the remarkable ability of brain organoids to generate primitive sensory structures that are light sensitive and harbor cell types similar to those found in the body," said neuroscientist Jay Gopalakrishnan of University Hospital Düsseldorf in Germany.
These organoids can help to study brain-eye interactions during embryo development, model congenital retinal disorders, and generate patient-specific retinal cell types for personalized drug testing and transplantation therapies."
Brain organoids are not true brains, as you might be thinking of them. They are small, three-dimensional structures grown from induced pluripotent stem cells - cells harvested from adult humans and reverse engineered into stem cells, that have the potential to grow into many different types of tissue......."
