The Artiodactyla example supports Van Valen's Law because its genera fit best under the semi-log transformation. Van Valen's Law states that extinction probability within the same ecological context does not depend on how long a species has already existed. When Van Valen's Law holds, species durations commonly follow exponential decay. A Type II result is treated as the statistical signature expected from memoryless macroevolution.
