Okay -- de-lurking to pose a question on behalf of my ten-year-old:

"My hypothesis is that sharks evolved earlier and separately from early bony 
fish.  I am wondering if Haikouichthys (sp?) evolved into sharks and 
heterostracans, the earliest jawless fish.  I am thinking that the 
heterostracans evolved into several different groups, including the osteoracans 
(sp?), which later evolved into placoderms and other advanced fish."

I hope this is entertaining enough. :-)  My apologies for any spelling errors.
