While Darwin ’ s concept of natural selection was intended to apply to whole organisms, Weismann modified Darwin's idea according to a process he called " germinal selection.

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

Essay by Sally O ’ Rielly, with an interview by Benjamin Weismann

" 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 also assumed that different species contain different developmental determinants.

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

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.

Weismann was born a son of high school teacher Johann ( Jean ) Konrad Weismann ( 1804 – 1880 ), a graduate of ancient languages and theology, and his wife Elise ( 1803 – 1850 ), née Lübbren, the daughter of the county councillor and mayor von Stade, on January 17, 1834 in Frankfurt am Main.

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.

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.

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.

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

Weismann successfully submitted two manuscripts, one about hippuric acid in herbivores, and one about the salt content of the Baltic Sea, and won two prizes.

Suddenly, at the peak of madness and confusion, the couples are engulfed by their follies, which transform the rundown theatre into a fantastical " Loveland ", an extravaganza even more grand and opulent than the gaudiest Weismann confection: " the place where lovers are always young and beautiful, and everyone lives only for love ".

The distinction is similar to that proposed by August Weismann, who distinguished between germ plasm ( heredity ) and somatic cells ( the body ).

In 1876 he suggested a hypothesis in explanation of heredity, resembling the germplasm theory subsequently elaborated by August Weismann, to the effect that the germinal protoplasm retains its specific properties from generation to generation, dividing in each reproduction into an ontogenetic portion, out of which the individual is built up, and a phylogenetic portion, which is reserved to form the reproductive material of the mature offspring.

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.

Daniels is a contributing editor to City Journal, published by the Manhattan Institute, where he is the Dietrich Weismann Fellow.

The term Darwinism had covered a wide range of ideas, many of which differed from Darwin's views, but it became associated with the minority view of August Weismann who went further than Darwin by rejecting inheritance of acquired characters and attributing all evolution to natural selection, a view also called neo-Darwinism.

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

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.
