Biological evolution has always gone hand in hand with cell evolution. The cells of eukaryotes, the most advanced branch in the evolutionary tree, are characterized by the fact that their nuclei are separated by a membrane. This membrane is in fact a dynamic labyrinth of interconnected compartments, and each one has a specific function. These compartments communicate with each other by means of specialized connectors and carriers. One example of these carriers is the transport vesicles that allow cell material to pass between the different compartments. The biogenesis of vesicular transport indicates the highest level of cell development, and in turn, the appearance of protein systems controlling this transport coincides with the appearance of the central nervous system.img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/HqK3MPb8jY0″ height=»1″ width=»1″ alt=»»/
