  • Animal kills do not cross over from Single Player to Multiplayer. The player must kill the full list of animals in one or the other, and not a combination, in order to acquire this achievement/trophy.
  • It is not necessary to skin the animals.
  • Track what kind of animals have been killed in the "Stats->Misc" menu. Animals that haven't yet been killed won't be listed at all (there are no "zeros" displayed).
  • The animals must be shot, not run over with a horse/wagon.


  • The name of the achievement is a play on Charles Darwin's theory of Natural selection. Players must seek out and eliminate animals, intervening in the natural process.
  • While shooting an animal, Marston will occasionally shout "I love natural selection!" or "Blame Darwin!"
  • The picture seems to be a meat cleaver and a pair of small meat hooks used when butchering. This is a reference to the equipment used in dressing animals, such as in meat factories.
  • Unnatural Selection is also an achievement in Grand Theft Auto Online for surviving all 10 rounds of a Survival game mode.
  • There's a glitch where killing a Jackalope will cancel out the need to kill a buffalo for this achievement
