What does the occurrence of the similar enzymes (Rag1 and Rag 2) in purple sea urchin that was primarily thought to found only in jawed vertebrates suggests about the evolution of adaptive immune system. Introduction: Immunity is the process of defense performed by an individual’s body in response to a foreign agent that invades the body. Innate immunity is a kind of immunity that is seen in individuals from birth. All animals possess innate immunity that is their first line of defense against any antigen. Adaptive immunity develops after encountering infectious agents.
