Multiple Choice
Leigh Van Valen (1973) tested the relationship between species longevity and extinction probability. Do these data support or reject the hypothesis that the longer a taxon has existed, the less likely it is to go extinct? 
A) These data would support the hypothesis; there is a strong correlation between the age of the taxa and the probability of extinction.
B) These data would reject the hypothesis; there is no relationship between age of the taxa and the probability of extinction.
C) These data are inconclusive; the pattern of the relationship between taxa longevity and probability of extinction is unclear.
D) These data indicate that the opposite of the hypothesis is true, that longer-lived taxa are much more likely to go extinct.
