August Weismann (1834 -- 1914) erkannte in der zweigeschlechtlichen Fortpflanzung, auch sexuelle Reproduktion genannt, die Hauptursache der biologischen Variabilität. Diese "Neodarwin'schen Theorie" aus dem Jahr 1900 konnte bestätigt und erweitert werden. Evolutionsforscher diskutieren aber noch 2011 die Frage, warum bei 99 % aller Tier- und Pflanzenarten die aufwändige sexuelle Fortpflanzung durchlaufen wird, obwohl hierbei nur die Weibchen über befruchtete Eizellen Nachkommen gebären, während die Männchen kinderlos sterben. Die Männer erzeugen aber über ihre Keimzellen (Spermien) variable Nachkommen und sind, zumindest bei Säugetieren, die eigentlichen Variationen-Generatoren der Evolution. Bei negativen Umwelteinflüssen oder Parasiten-Befall ist die biologische Variabilität überlebensnotwendig, da während dieser Krisen nur wenige Individuen überdauern, sich fortpflanzen und die Population in der Generationen-Abfolge erhalten. Im Video wird auch die sexuelle Selektion ("Damenwahl im Tierreich") behandelt und die folgende aktuelle Schlussfolgerung gezogen: Weibchen gebären und erhalten somit die Art, Männchen schaffen Vielfalt. Die Weiterentwicklung des "Neodarwinismus" wird in unserem Video Nr. 8 "Was sind Evolutionstheorien?" (ca. November 2011) beschrieben, wobei wir dort u. a. auch auf die Epigenetik eingehen.

Darwinism is a theory of biological evolution developed by Charles Darwin and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called Darwinian theory. It originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance when Charles Robert Darwin published On the Origin of Species, including concepts which predated Darwin's theories, but subsequently referred to specific concepts of natural selection, the Weismann barrier or in genetics the central dogma of molecular biology. Though it usually refers strictly to biological evolution, the term has been used by creationists to refer to the origin of life, and has even been applied to concepts of cosmic evolution, both of which have no connection to Darwin's work. It is therefore considered the belief and acceptance of Darwin's, and his predecessors, work in place of other theories including divine design and extraterrestrial origins. The term was coined by Thomas Henry Huxley in April 1860, and was used to describe evolutionary concepts in general, including earlier concepts such as Spencerism. Many of the proponents of Darwinism at that time, including Huxley, had reservations about the significance of natural selection, and Darwin himself gave credence to what was later called Lamarckism. The strict neo-Darwinism of August Weismann gained few supporters in the late 19th century. During this period, which has been called "the eclipse of Darwinism", scientists proposed various alternative evolutionary mechanisms which eventually proved untenable. The development of the modern evolutionary synthesis from the 1930s to the 1950s, incorporating natural selection with population genetics and Mendelian genetics, revived Darwinism in an updated form.

Karl Pearson A eugenicist who applied his social Darwinism to entire nations, Pearson saw "war" against "inferior races" as a logical implication of his scientific work on human measurement: "My view -- and I think it may be called the scientific view of a nation," he wrote, "is that of an organized whole, kept up to a high pitch of internal efficiency by insuring that its numbers are substantially recruited from the better stocks, and kept up to a high pitch of external efficiency by contest, chiefly by way of war with inferior races." He reasoned that, if August Weismann's theory of germ plasm is correct, the nation is wasting money when it tries to improve people who come from poor stock. In The Myth of the Jewish Race[9] Raphael and Jennifer Patai cite Karl Pearson's 1925 opposition (in the first issue of the journal Annals of Eugenics which he founded) to Jewish immigration into Britain. Pearson alleged that these immigrants "will develop into a parasitic race"...taken on the average, and regarding both sexes, this alien Jewish population is somewhat inferior physically and mentally to the native population". Pearson achieved widespread recognition across a range of disciplines and his membership of, and awards from, various professional bodies reflects this: 1896: elected FRS: Fellow of the Royal Society[2] 1898: awarded the Darwin Medal[10] 1911: awarded the honorary degree of LLD from the University of St Andrews 1911: awarded a DSc from University of London 1920: offered (and refused) the OBE 1932: awarded the Rudolf Virchow medal by the Berliner Anthropologische Gesellschaft 1935: offered (and refused) a knighthood He was also elected an Honorary Fellow of King's College Cambridge, the Royal Society of Edinburgh, University College London and the Royal Society of Medicine, and a Member of the Actuaries' Club. http://en.wikipedia.org/wiki/Karl_Pearson

Interview with Dr. Carl Werner, Executive Producer of Evolution: The Grand Experiment video series. He discusses some of the highlights of the first episode. This DVD won four film awards and was the center of controversy at the Society of Vertebrate Paleontology. Members of the Society of Vertebrate Paleontology were upset that their interviews were used as supporting evidence against evolution. Once the DVD reached the Louisiana Legislature Committee on Education, a firestorm erupted on Amazon and 5,600 comments followed.

Yahoo Daily News 2013-01-20Friedrich Leopold August Weismann (Frankfurt am Main, 17 January 1834 – Freiburg, 5 November 1914) was a German evolutionary biologist.Ernst Mayr ranked him the second most notable evolutionary theorist of the 19th century, after Charles Darwin. Weismann became the Director of the Zoological Institute and the first Professor of Zoology at Freiburg.
His main contribution was the germ plasm theory, according to which (in a multicellular organism) inheritance only takes place by means of the germ cells—the gametes such as egg cells and sperm cells. Other cells of the body—somatic cells—do not function as agents of heredity. The effect is one-way: germ cells produce somatic cells and are not affected by anything the somatic cells learn or therefore any ability the body acquires during its life. Genetic information cannot pass from soma to germ plasm and on to the next generation. This is referred to as the Weismann barrier. This idea, if true, rules out the inheritance of acquired characteristics as proposed by Jean-Baptiste Lamarck.
