Question
Chapter 21, Problem 21RQ
Summary Introduction
To explain: The probable characteristics of most recent common ancestors of insects.
Introduction: Studies of insect evolution is aided by molecular, embryological, morphological studies along with bioinformatics. The origin of insects can be dated back to about 480 million years ago. Insect evolution can be traced back to the Ordovician period during which the terrestrial plants also appeared.
Summary Introduction
To enlist: The major lineages that descended from common ancestors of insects.
Introduction: Lineages can be defined as a sequence of species that are evolved from their ancestors. These species have some similar characteristics that they have inherited from their ancestors.
