Disruptive Selection

Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. This evolutionary process is believed to be one of the main driving forces behind sympatric speciation.
