Chapter 23.4, Problem 3LO
Summary Introduction
To determine: The way in which a phylogenetic tree can indicate the timing of species diversification.
Introduction: Species diversification is the evolution that explains the collective fluctuations that occur in the heritable traits of a population. It can produce in diversification in a species that is microevolution or diversification among species or macroevolution.
