In other terms, the confidence intervals are evaluated using the given confidence level from an endless number of independent samples.

#Unit 9. Diversity of Life Forms

Phylogenetic relationships among species in a radiation are difficult to determine for two related reasons.                                                                 

a. During the short time between two successive speciation events, few new mutations are fixed.                                                                               

b. Incomplete lineage sorting may occur during rapid diversification.
