Anthropology (also known as Thriving from a Riff or Thriving on a Riff) is a bebop-style jazz composition that is credited to Charlie Parker and Dizzy Gillespie. Parker stated in 1949 that Gillespie had played no part in its writing, and that others had added the trumpeter as co-composer. It is a contrafact, being based on the harmony of I Got Rhythm.
