Chapter 9- See the light!!!

Shubin's story of his adventure to China really allowed this chapter to take flight. The finding of ancient eyes and primitive forms of vision gave way to the history of photoreceptors. As he said many times, Shubin stated that early forms of vision only had two photoreceptors where as modern animals have three; one for black and white, and two for color.

Certain genetic eye disorders are the same DNA issue in flies, mice, and humans. Just to think about it, the complex human body can be compared at the genetic level to one of a simple fly. It's intriguing. The formation of the eyeless flies and their mutation kind of weirded me out. The scientists mutating the flies so that they would grow eyes on their legs seemed cruel even if it is "justified".
