Query: Mammalian cochlea as a physics guided evolution-optimized hearing sensor   Nonlinear physics plays an essential role in hearing, from sound signal
generation to sound sensing to the processing of complex sound environments. We
demonstrate that the evolution of the biological hearing sensors demonstrates a
dramatic reduction in the solution space available for hearing sensors due to
nonlinear physics principles. More specifically, our analysis hints at that the
differences between amniotic lineages hearing, could be recast into a scaleable
and a non-scaleable arrangement of nonlinear sound detectors. The scalable
solution employed in mammals, as the most advanced design, provides a natural
context that demands the ultimate characterization of complex sounds through
pitch.
