Whether the pattern of rate of evolutionary changes over time intervals holds true for most characters. Introduction: The degree and rate of evolutionary changes vary in all organisms. For example: the rates of evolutionary change measured over short time intervals are often very high. However, rate of evolutionary changes that is measured over long time intervals are generally much lower.
