Description:

In this exercise, students use random numbers drawn from a telephone directory to create a series of phylogenetic trees based on the assumptions of constant probability of origination and extinction per lineage through time. They use these trees to derive diversity trends and compare their model results to a real phylogeny of echinoids to test the model assumptions. They interpret any deviations and propose means of testing their ideas.
