text: Yo, listen up, I got a story to tell,
  'Bout G protein-coupled receptors, they ringin' the bell.
  In eukaryotic signal transduction, they play a key role,
  But the early origins in metazoans got us in a black hole.
  
  We're on a mission to uncover the truth,
  Identify and classify GPCRs in Amphimedon queenslandica, that's the move.
  This sponge is a member of the earliest diverging metazoan crew,
  Porifera representin', yeah, we stay true.
  
  But we ain't stoppin' there, nah, we goin' deep,
  Phylogenetic comparisons, that's the technique.
  Checkin' sponge GPCRs against eumetazoans and bilaterians,
  To understand the roots of metazoan evolution, ain't no denyin'.
  
  So let's break it down, piece by piece,
  Unravel the mysteries, let the knowledge increase.
  GPCRs in the game since the beginning of time,
  Shapin' our world, yo, it's a paradigm.
