The Atacama Desert, a 1000km stretch of parched wasteland, separates it from Peru to the north. And to the west, only a few islands dotted in the Pacific Ocean break the waves that roll onto Chileâs coast from Australasia.
What is a mutation? A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
mutation(n.) (Biol.) (a) As now employed (first by de Vries), a cellular process resulting in a sudden inheritable variation (the offspring differing from its parents in some well-marked character or characters) as distinguished from a gradual variation in which the new characters become fully developed only in the course of many generations.
