"Taq polymerase" is a DNA polymerase derived from a specific
thermophile, Thermus aquaticus.  Other thermophilic organisms
have different versions of DNA polymerase.  Taq polymerase is
of consequence to humanity because it was the polymerase used
by Mullis et al in the invention of the polymerase chain
reaction (PCR), for which Mullis was award the Nobel Prize for
