Chapter 10 Quotes

Jellyfish do not have either Pax 6 or Pax 2: they arose before those genes hit the scene. But in the box jellyfish's genes we see something remarkable. The gene that forms the eyes is not Pax 6, as we'd expect, but a sort of mosaic that has the structure of both Pax 6 and Pax 2. In other words, this gene looks like a primitive version of other animals' Pax 6 and Pax 2.

Explanation and Analysis:
As Shubin explains the history and development of the human eye, he examines the genes that control the production of the eye in embryos. This gene, called Pax 6, is found in many other animals – even those that don’t have the same type of eye as humans. Jellyfish are some of the simplest animals on the planet, and likely developed between 700 and 500 million years ago. This means they developed before many fine tuned organs fully adapted. Yet remarkably, the box jellyfish genome includes a primitive version of the Pax 6 gene that seems to be mixed with Dolorem et quae. Exercitationem non aut. Eveniet dolor non. Incidunt dolores sunt.
