DESCRIPTION:Living organisms are highly complex chemical syste
 ms that exploit a small constellation of universal
 ly conserved metabolites. The chemical unity of th
 ese metabolites provides compelling evidence that 
 a simple set of predisposed reactions predicated t
 he appearance of life on Earth. Conversely\, tradi
 tional prebiotic chemistry has produced highly com
 plex mixtures that bear little resemblance to the 
 core metabolites of life. The complexity of prebio
 tic chemistry until recently had suggested that el
 ucidating life’s origins was an insurmountable tas
 k\, but prebiotic systems chemistry is now providi
 ng unprecedented scope to explore the origins of l
 ife and an exciting new perspective on a 4 billion
 -year-old problem. At the heart of this new\nsyste
 ms approach is an understanding that individual cl
 asses of metabolites cannot be considered in isola
 tion if the chemical origin of life on Earth is to
  be successfully elucidated. In this talk several 
 recent advances that suggest that nucleotides and 
 proteinogenic peptides are predisposed chemical st
 ructures that can be facilely synthesised in water
  will be presented.\n
