Epigenetics is the study in the field of genetics‚ that examines heritable changes in gene expression in organisms (active versus inactive genes) that doe not involve changes in the underlying DNA sequence. This means a change in phenotype occurs‚ which changes the observable characteristics of an organism‚ while the genotype of the organisms stays the same. Although‚ epigenetic changes are regular and naturally occurring‚ other factors can influence the phenotype of an organism. Some of these factors

Also significantly altering evolution is the unpredictable movement of tectonic plates
