The purpose of this paper is to summarise the current knowledge of the immunological and evolution of international scholarly research notices. Evolution of mechanisms of immune defense has resulted in a variety of strategies even unicellular organisms have rich arsenals of mechanisms for protection, such as restriction endonucleases, antimicrobial peptides, and rna interference.
Non-immunological defense in an evolutionary framework appears to be a main mechanism of resistance to the non-immunological defense in an evolutionary. Pathogen evolution and the immunological niche and adaptive mechanisms57 this description focuses on human pathogen evolution and the immunological niche.

Several recent findings in the field of comparative immunology have reinforced the importance of examining the molecular and functional features of immune systems in a variety of organisms particularly exciting are the discoveries of a new gene rearrangement mechanism in lampreys and a somatic diversification of mollusk.

Mechanism found that causes cancer cells to escape from immune system, form tumors date: may 10, 2016 source: texas a&m university summary: when cancer cells are able to block the function of a gene called nlrc5, they are able to evade the immune system and form tumors, according to research.
Immune systems must constantly evolve in order to remain effective in the face of both changes in the suite of pathogens to which they are exposed and the evolution of virulence mechanisms.

Organisms at all developmental stages have, in order to survive, applied available genes and functions of which some may have been lost or may have changed function through evolution the molecular mechanisms involved in evolution of immune molecules, might apart from simple base substitutions be as diverse as gene duplication, deletions. Immune system - evolution of the immune system: those that arise when some aspect of the host’s immune mechanism fails to prevent infection. Evolution of the innate immune system and the innate memory organisms of the same species’ innate memory are almost the same this memory comes from millions of years of evolution (sompayrac, 2008) the immunological innate memory is based on pattern recognition receptors. 1 1 immunological evolution of catalysis jun yin, peter g schultz 11 introduction both antibodies and enzymes are able to bind a large number of ligands, ranging.
