Weismann barrier

The Weissman barrier is the idea, put forth by August Weissman, that mutations in a person’s somatic cells (cells except for egg and sperm cells) would not be passed on to germ cells (egg and sperm cells) and therefore would not be acquired by successive generations. Corrado Spadafora: Does The Weismann Barrier Really Exist? 05/15/2015 04:21 pm ET Updated Dec 06, 2017 Corrado Spadafora 's work 20 some years ago on the organization of chromatin in sperm cells revealed that "sperm cells can behave as vectors of foreign genetic information to embryos at fertilization." Die Weismann-Barriere ist die Hypothese, dass die Übernahme von Informationen erworbener Eigenschaften (sogenannte Modifikationen) in die Erbinformation von Keimzellen unmöglich ist und somit erworbene Eigenschaften nicht vererbbar sind. http://www.theaudiopedia.com What is WEISMANN BARRIER?

More specifically, Weismann set out to demonstrate that only germ cells contribute to inheritance. That, somatic cells are produced by germ cells, but that somatic cells do not influence the production of germ cells. Today we believe this to be true, and refer to it as the "Weismann barrier".

That, somatic cells are produced by germ cells, but that somatic cells do not influence the production of germ cells. Today we believe this to be true, and refer to it as the "Weismann barrier". The Weismann barrier, proposed by August Weismann, is the principle that hereditary information moves only from genes to body cells, and never in reverse.In more precise terminology hereditary information moves only from germline cells to somatic cells (that is, soma to germline feedback is impossible).

Suzan Mazur: Is evolutionary science moving too quickly for even a new integrative synthesis to be relevant for very long? The effect is one-way: germ cells produce somatic cells and are not affected by anything the somatic cells learn, or any ability the body acquires during its life.

Weismann distinguished somatic cells from germ cells [9] in multi-cellular organisms, and he proposed that changes made to somatic cells cannot be passed to germ cells [9] or to the next generation, a theory later called the Weismann Barrier. Weismann therefore rejected the possibility of the inheritance of acquired characteristics, if those

Weismann therefore rejected the possibility of the inheritance of acquired characteristics, if those The Weismann barrier has long been regarded as a basic tenet of biology. However, upon close examination of its historical origins and August Weismann’s own writings, questions arise as to whether such a status is warranted. As scientific research has advanced, the persistence of the concept of the barrier has left us with the same dichotomies Weismann contended with over 100 years ago Weismann is much admired today. Ernst Mayr thought he was "one of the great biologists of all time", and ranked him "the second most notable evolutionary theorist of the 19th century", after Charles Darwin.
