                 Life at the edge of quantum chaos


Why life persists at the edge of chaos is a question at the very heart 
of evolution. Here we show that molecules taking part in biochemical 
processes from small molecules to proteins are critical quantum 
mechanically. Electronic Hamiltonians of biomolecules are tuned exactly 
to the critical point of the metal-insulator transition separating the 
Anderson localized insulator phase from the conducting disordered metal 
phase. Using tools from Random Matrix Theory we conrm that the energy 
level statistics of these biomolecules show the universal transitional 
distribution of the metal-insulator critical point and the wave 
functions are multifractals in accordance with the theory of Anderson 
transitions. The ndings point to the existence of a universal mechanism 
of charge transport in living matter. The revealed bio-conductor 
material is neither a metal nor an insulator but a new quantum critical 
material which can exist only in highly evolved systems and has unique 
material properties.
