Weismann realised that the cells that produce the germ plasm, or gametes ( such as sperm and egg in animals ), separate from the somatic cells that go on to make other body tissues at an early stage in development.

He reevaluates August Weismann's model of the cell compartmentalization of somatic and germline cell lineages ( see Weismann barrier ), and argues that the vision of the individual taken by the modern synthesis is insufficient to explain the early evolution of development or ontogeny.

Prior to his career in philosophy and education with Dr Adler, Weismann was a consultant in the field of architecture, construction management and exhibit design and fabrication.

Max Weismann is an American philosopher and a long-time friend and colleague of Mortimer Adler, with whom he co-founded the Center for the Study of the Great Ideas in Chicago.

In 1873, August Weismann postulated the equivalence of the maternal and paternal germ cells for heredity.

The strict neo-Darwinism of August Weismann gained few supporters in the late 19th century.

The origins of the concept of eugenics began with certain interpretations of Mendelian inheritance, and the theories of August Weismann.

For the safety of gene therapy, the Weismann barrier is fundamental in the current thinking.

However, there are indications that the Weismann barrier can be breached.

The inheritance of acquired traits was shown to have little basis in the 1880s when August Weismann cut the tails off many generations of mice and found that their offspring continued to develop tails.

The significance of meiosis for reproduction and inheritance, however, was described only in 1890 by German biologist August Weismann, who noted that two cell divisions were necessary to transform one diploid cell into four haploid cells if the number of chromosomes had to be maintained.

The minority view of August Weismann, that natural selection was the only mechanism, was called neo-Darwinism.

As part of the disagreement about whether natural selection alone was sufficient to explain speciation, George Romanes coined the term neo-Darwinism to refer to the version of evolution advocated by Alfred Russel Wallace and August Weismann with its heavy dependence on natural selection.

Weismann and Wallace rejected the Lamarckian idea of inheritance of acquired characteristics, something that Darwin had not ruled out.

Friedrich Leopold August Weismann ( 17 January 1834 – 5 November 1914 ) was a German evolutionary biologist.

Weismann became the Director of the Zoological Institute and the first Professor of Zoology at Freiburg.

This is referred to as the Weismann barrier.

The idea of the Weismann barrier is central to the Modern evolutionary synthesis, though it is not expressed today in the same terms.

Weismann was one of the first biologists to deny soft inheritance entirely.

Weismann's ideas preceded the rediscovery of Gregor Mendel's work, and though Weismann was cagey about accepting Mendelism, younger workers soon made the connection.

Weismann is much admired today.
