Chapter 20.5, Problem 2C
Summary Introduction
To explain: The ways in which preadaptation facilitates macroevolution.
Introduction: Inheritance is the basis of evolution. The study of the evolution of an organism is termed as phylogeny. Evolution is majorly divided into two categories: microevolution (evolution of a population on a small scale) and macroevolution (evolution of all the population on a larger scale).

A second question, closelyrelated to the first, is how do genetic differences among species map onto phenotypic differences? Third, what is the role of development in either constraining or enhancing evolutionary change in characters? That is, how does development affect “evolvability”? Fourth, how does developmental information help usidentify homologous characters, or even define homology?
