(Long pause.) I am not simply saying that genetic activity can be changed, for example, through something like a nuclear accident, but that highly beneficial alterations can also take place in genetic behavior, as in your terms the genetic structure not only prepares the species for any contingency, but also prepares it by triggering those characteristics and abilities that are needed by the species at any given time, and also by making allowances for such future developments (all quite forcefully).

Ruburt read an article about the development of a strain of mice without thymus [glands]. Since the thymus is very important in the necessary process of maintaining bodily resistance to disease, these particular mice have little resistance. They are bred and sold for experimental purposes. The intent of such procedures is to promote the quality of human life, to study the nature of diseases, and hopefully apply what is learned to some of the lives of human beings. Mice are not considered human. They are not. So like any animal, they are thought of as dispensable, sacrificed to a fine humanitarian end.

But granted or not, the idea of any sort of genetic preparation for future contingencies collides with the very powerful theory of evolution, which holds that evolutionary, genetic changes take place only through natural selection and chance mutations (although random or chance mutations are generally regarded as mistakes on nature’s part). There are many unsolved challenges here. I can even see Seth’s material in this session being scientifically dismissed as another version of old, discredited Lamarckian theories. (Jean Baptiste de Monet de Lamarck [1744–1829] was a French naturalist who advocated that certain modifications of an organism’s structure and function could develop in response to environmental factors, and that these “acquired characters” could be inherited. Lamarck’s work has been widely misunderstood, however. It still has value, and recently has been employed in some remarkable scholarly studies that show how, in scientific terms, evolution can take place through means other than natural selection and chance mutations.)
