Tasmanian devils once inhabited most of present-day Australia, but only an isolated population on the island of Tasmania has survived to the present day. Which of the following processes has likely affected Tasmanian devils as a result of this history?
A) a higher mutation rate
B) stronger natural selection
C) a genetic bottleneck
D) gene flow
