Bøger af August Weismann

Das Keimplasma: Eine Theorie Der Vererbung (1892) ist ein bahnbrechendes Buch des deutschen Biologen August Weismann. In diesem Werk stellt Weismann seine Theorie der Vererbung vor, die besagt, dass die Vererbung von Eigenschaften ausschlie�����lich durch die Keimzellen erfolgt und nicht durch die somatischen Zellen des Organismus beeinflusst wird. Weismann argumentiert, dass das Keimplasma, das sich in den Keimzellen befindet, unver�����nderlich ist und somit die genetische Information von einer Generation zur n�����chsten weitergibt. Er pr�����gte den Begriff der ""Keimbahn"", um die Trennung von Keimzellen und somatischen Zellen zu beschreiben. Das Buch war ein Meilenstein in der Geschichte der Genetik und beeinflusste die Entwicklung der modernen Genetik und Evolutionstheorie.This Book Is In German.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

Die Bedeutung der sexuellen Fortpflanzung f�����r die Selektions-Theorie ist ein Buch von August Weismann, das erstmals im Jahr 1886 ver������ffentlicht wurde. Es ist ein wichtiger Beitrag zur Evolutionstheorie und besch�����ftigt sich mit der Frage, warum sexuelle Fortpflanzung in der Natur existiert und welche Auswirkungen sie auf die nat�����rliche Selektion hat. Weismann argumentiert, dass sexuelle Fortpflanzung eine wichtige Rolle bei der Schaffung von genetischer Vielfalt spielt, die es Organismen erm������glicht, sich an sich �����ndernde Umweltbedingungen anzupassen. Dar�����ber hinaus diskutiert er die Theorie der Vererbung von Merkmalen und wie sie mit der nat�����rlichen Selektion interagiert. Das Buch ist ein wichtiger Meilenstein in der Geschichte der Evolutionstheorie und hat bis heute einen gro�����en Einfluss auf die Forschung in diesem Bereich.This Book Is In German.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

""Die Allmacht der Naturzuchtung: Eine Erwiderung an Herbert Spencer"" ist ein Buch von August Weismann, das 1893 ver������ffentlicht wurde. In diesem Werk setzt sich Weismann mit den Theorien des britischen Philosophen Herbert Spencer auseinander, der die Evolution als einen Prozess der Anpassung an die Umwelt betrachtete. Weismann argumentiert jedoch, dass die Evolution durch nat�����rliche Selektion und nicht durch die Anpassung an die Umwelt bestimmt wird. Er betont die Bedeutung der Vererbung und der Variation in der Evolution und weist darauf hin, dass die Umwelt lediglich den Selektionsdruck auf die Organismen aus�����bt. Das Buch ist eine wichtige Arbeit in der Geschichte der Evolutionsbiologie und hat dazu beigetragen, die Bedeutung der Vererbung und der Variation in der Evolution zu betonen.This Book Is In German.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
