Abstract

Suggestions are made for the measurement of evolutionary rates of metrical characters. The unit of time may be the year or the generation. The unit for the character may be a unit increase in the natural logarithm of a variate, or alternatively one standard deviation of the character in a population at a given horizon. Examples are given from mammalian paleontology of the calculation of such rates.
