This hypothesis is not consistent with the evidence that most of the hominid evolution took place in savanna environment and not in tropical rainforests.[48] Humans living in hot and sunny environments have darker skin than humans who live in wet and cloudy environments.[2] The antimicrobial hypothesis also does not explain why some populations (like the Inuit or Tibetans) who live far from the tropics and are exposed to high UVR have darker skin pigmentation than their surrounding populations.[3]
