Summary Introduction

To determine: In what way the phylogenetic analyses of predators and prey, or of parasites and hosts, help in the determination of presence or absence of an evolutionary arms race.

Introduction: The“evolutionary arms race” explains the competition between a set of the coevolution species by the means of “acquiring adaptabilities” and “counter adaptations” in response to each other. The evolutionary arms race is also known as “escalation”. The survival of species of each group depends upon the adaptation rate of each other species, which sums up the criteria of a better way to attack and for the other species, the response will be to dodge or counter attack.
