of flies and men :P

In this chapter the main concept that "all organs can be traced to one of the three layers of tissue in the developing embryo. Particularly mind boggling about this concept is that is depicts just how neat the formation the human body is as before learning this I would not even know where the human body would begin. Its organization doesn't end there either as all the layers correspond to organization of the human body for example the endoderm controls the formation of many inner structures of the body.

As Shubin delineates ideas about fundamental questions about our bodies. What interested me was how Mangold's discovery of the Organizer as that infinitesimal piece of tissue could have such a complex information as to how to create the human body.

This chapter also reminded me about just how useful flies are as scientists used them for countless genetic experiements. These tiny pests are the ones that pave the path to understand the mysteries the major body plan genes active in the human embryo.

When Shubin talked about our similarities with sea anemones this also made me think about evolution and how far its domain reaches as Martindale and his colleagues proved that we share the inner recipe with even the utterly different jelly fish.
