In it Burnet expanded the ideas of Talmage and named the resulting theory the "clonal selection theory". He further formalised the theory in his 1959 book The Clonal Selection Theory of Acquired Immunity. He explained immunological memory as the cloning of two types of lymphocyte. One clone acts immediately to combat infection whilst the other ...
The goal is not to create cloned human beings (called "reproductive cloning"), but rather to harvest stem cells that can be used to study human development and to potentially treat disease. While a clonal human blastocyst has been created, stem cell lines are yet to be isolated from a clonal source. [14]
The theory is now sometimes known as Burnet's clonal selection theory, [113] which overlooks the contributions of Ehrlich, Jerne, Talmage, and the contributions of Lederberg, who conceptualised the genetics of clonal selection. [114] Burnet's work on graft-versus-host was in collaboration with Lone Simonsen between 1960 and 1962.
This idea is known as clonal selection theory. At the time, many leading scientists including Linus Pauling and James Watson completely rejected the idea, but repeated experimentation intended to disprove the theory actually served to build up a large body of evidence supporting Burnet and Jerne's theory.

Human cloning is banned by the Presidential Decree 200/97 of 7 March 1997. [48] Australia: Illegal [50] [49] Legal [51] Australia has prohibited human cloning, [52] though as of December 2006, a bill legalizing therapeutic cloning and the creation of human embryos for stem cell research passed the House of Representatives. Within certain ...
Edelman reasoned that the N-CAM molecule which is used for self-self recognition and adherence between neurons in the nervous system gave rise to their evolutionary descendants, the antibodies, who evolved self-nonself recognition via antigen-adherence at the origins of the vertebrate antibody-based immune system. If clonal selection was the ...
Clonal Selection Pseudo code on AISWeb; CLONALG in Matlab developed by Leandro de Castro and Fernando Von Zuben; Optimization Algorithm Toolkit in Java developed by Jason Brownlee which includes the following clonal selection algorithms: Adaptive Clonal Selection (ACS), Optimization Immune Algorithm (opt-IMMALG), Optimization Immune Algorithm (opt-IA), Clonal Selection Algorithm (CLONALG ...
The Luria–Delbrück experiment (1943) (also called the Fluctuation Test) demonstrated that in bacteria, genetic mutations arise in the absence of selective pressure rather than being a response to it. Thus, it concluded Darwin's theory of natural selection acting on random mutations applies to bacteria as well as to more complex organisms.
