Mammals (synapsids) are not descended from lizards, snakes, and crocodiles (diapsids), while turtles (anapsids) are an entirely different matter as well. All three groups descend from the advanced amphibians of the late Carboniferous, so, yes, we do share some brain structure with the others but, really, the organization is quite a bit different. It is best to realize that, today, we have the ambphibia, anapsida (turtles), synapsida (mammels), and diapsida (lizards and snakes, the tuatara, crocodilians, and archosaurs (birds))." == Good lord, I had no idea! How did you get to be so danged smart? ;-) But you know what I mean, or meant, though, don't you, metaphorically speaking? (Maybe not!) What happened to that reptilian brain I keep hearing about that we have? Kit - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
