The read was interesting as always. Shubin’s personal view of the scientific world is not boring at all and always keeps me coming back. It amazes me that even sponges are similar to us in their own way. For example, their cells have a division of labor, the cells can communicate, the cells function as an individual, and the sponge has cell adhesion and a scaffolding apparatus like humans have. My question is: Subin goes on saying that the world may not have been ready for bodies and so they did not arise sooner than they did, but why did bodies arise so suddenly and not through the longer process of evolving into bodies?
