... diverse perspectives on a much larger nexus that is as yet largely obscure. This larger web is full of interacting molecules, neurons, brain areas, and entire organisms, all changing through development and over evolutionary time. Neuroscience as a field is already complex, but when one adds the ... dimension, the complexity becomes truly awesome and certainly beyond what one can expect to capture in just a few colloquium papers. Nonetheless, some recurring themes emerge....

... One idea running through several contributions is that evolution and development are linked. Historically, evolutionary neurobiologists visualized evolutionary changes as transformations between adult forms. This ... , 2011). According to this view, evolutionary changes must involve changes in development, which can be inferred by comparing developmental mechanisms and trajectories between species. Such comparative developmental studies can reveal the mechanistic basis of evolutionary change and thus complement ... that address the ecological and behavioral contexts in which those changes might have been adaptive....

... of the chapters is that homologies at one level of biological organization may or may not be linked to homologies at higher or lower levels (Brigandt, 2002). For example,...

... change their functions over evolutionary time, this possibility is not easily dismissed. Even complex networks of interacting genes are, as Jarvis and colleagues argue in Chapter 4, capable of becoming involved in the assembly of novel structures. If similar changes in function occur independently ...

... circuits. If neurons can change their behavioral functions over evolutionary time, then homologous behaviors may involve nonhomologous neurons, and nonhomologous behaviors can involve at least a few homologous neurons. This point has been made before by various authors (Striedter and Northcutt, ... ), but it continues to befuddle the unsuspecting mind. As mentioned earlier, the task of understanding how the tangled bank of molecules, cells, structures, organisms, and behaviors has managed to transform itself in evolutionary time has only just ...
