Weismann envisioned a simple organism model with a strict separation between germline and soma—the so-called Weismann barrier—in which no age-related deterioration acquired by somatic cells could ever be transmitted via germline to the next generation, which is always born young.

Weismann not only described the existence of the barrier between germinal and somatic cells, but also attempted to demonstrate it experimentally.However, he was not very fortunate in his choice of experimental system.His experiments, in which he cut off the tails of mice over a great many generations to demonstrate that mice would continue to be born with tails of the same length, yielded the The Weismann barrier has long been regarded as a basic tenet of biology.

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. Weismann's barrier. Weismann advocated the germ plasm theory. Weismann set out the concept in his 1892 book Das Keimplasma: eine Theorie der Vererbung (The Germ Plasm: a theory of inheritance). [5] The Weismann barrier was of great importance in its day and among other influences it effectively banished certain Lamarckian concepts: in particular, it would make Lamarckian inheritance from changes to the body (the soma) difficult or impossible. [6] The Weismann barrier, proposed by August Weismann, is the strict distinction between the "immortal" germ cell lineages producing gametes and "disposable" somatic cells, in contrast to Charles Darwin's proposed pangenesis mechanism for inheritance.
