LEARNING OBJECTIVES

After reading this chapter, you should be able to:
• Understand that invertebrates rely exclusively on the use of innate immune

mechanisms to protect themselves against infectious agents.
• Explain how the jawless fish mainly rely on innate immunity, although they also
possess a remarkably complex and diverse adaptive antigen-binding receptor

system.
• Understand that cartilaginous fish were the first vertebrates to utilize an adaptive
immune system.

• Define the immunological “big bang.”
