Evolution is believed to start out from completely random mutation.This makes us unable to predict future mutations. However, researchersrecently suggested that mutation may not always be random. Individualorganisms can respond to their environment with a change in theirphysical composition. For example, snails develop sturdier shells as adefense when exposed to predators, and this is called a plasticresponse. The mechanism behind this phenomenon is the addition ofdifferent molecules to the DNA, and this is known as epigenetics.These molecules do not alter the DNA sequence itself, but control ...
