But the neural circuitry that led to the human love song -- not to mention birdsongs, frog thrums and mating calls of all manner of vertebrates -- was likely laid down hundreds of millions of years ago with the hums and grunts of the homely piscine.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.sciencedaily.com/releases/2008/07/080717140435.htm"><P>By mapping the developing brain cells in newly hatched midshipman fish larvae and comparing them to other species, Andrew H.
