Sally Durant Plummer, " blond, petite, sweet-faced " and at 49 " still remarkably like the girl she was thirty years ago ", a former Weismann girl is the first guest to arrive ; her ghostly youthful counterpart moves towards her.

Former Weismann performers at the reunion include Max and Stella Deems, who lost their radio jobs and became store owners in Miami ; Solange La Fitte, a coquette, who is still vibrant three decades later ; Hattie Walker, who has outlived five younger husbands ; Vincent and Vanessa, former dancers who now own an Arthur Murray franchise ; Heidi Schiller, for whom Franz Lehár once wrote a waltz ( or was it Oscar Straus?

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.

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

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.

His son Julius Weismann ( 1879-1950 ) was a composer.

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.

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 was translated into English, and though he was influential, it took many years for the full significance of his work to be appreciated.

Huxley was the most important biologist after August Weismann to insist on natural selection as the primary agent in evolution.

Lochner's case was argued by Henry Weismann ( who had been one of the foremost advocates of the Bakeshop Act when he was Secretary of the Journeymen Bakers ' Union ).

* An examination of Weismannism ( 1893 ) ( August Weismann was the leading evolutionary theoretician at the turn of the 19th century )

The gearbox is proprietary and was developed by Weismann.

A useful macroscopic model that combines an electric field with DLA was developed by Niemeyer, Pietronero, and Weismann in 1984, and is known as the dielectric breakdown model ( DBM ).

The thread was later picked up by August Weismann in 1889, who argued that the purpose of sex was to generate genetic variation, as is detailed in the majority of the explanations below.

The term germ plasm was first used by the German biologist August Weismann ( 1834 – 1914 ).

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.

This was known even before Mendel by medical men interested in human races ( Wells, Lawrence ), and especially by Weismann.

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.

The " Alexanderlied " with German translation was first edited by Heinrich Weismann ( 2 vols., Frankfurt, 1850 ); the best edition is by Karl Kinzel in " Germanistische Handbibliothek ", ed.

Immediately after university, Weismann took on a post as assistant at the Städtische Klinik ( city clinic ) in Rostock.

After this work, Weismann accepts evolution as a fact on a par with the fundamental assumptions of astronomy ( e. g. Heliocentrism ).

After Huxley the most important influence on his thought was August Weismann, the German zoologist who rejected Lamarkism, and wholeheartedly advocated natural selection as the key force in evolution at a time when other biologists had doubts.

Weismann ’ s view was founded on the belief that biological inheritance is inconceivable except by way of germ plasm from parents to offspring.

" On the assumption that behavior cannot affect genes, Weismann argued that only genetic mutation, not adaptations on the part of a struggling organism, could significantly alter the developmental patterns inherited by progeny.

Weismann ’ s developmental concept was based on a mistaken interpretation of an 1882 experiment carried about by Wilhelm Roux, in which Roux killed one of the cells of a frog embryo at the two-cell stage.

For instance, Ilya Weismann, deputy director of competing beverage company Baltic, was assassinated on January 10, 2000.

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.

On the soon-to-be demolished stage of the Weismann Theatre, a reunion is being held to honor Weismann's " Follies " shows past, and the beautiful chorus girls who once performed there.

Finally Mr. Weismann enters to greet his guests.

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.

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

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 is much admired today.
