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.
