Book excerpt: Excerpt from Studies in the Theory of Descent, Vol. 2 of 2 If variability is to be understood as indicating the period of re-modelling of a living form, whether in its totality or only in single characters or groups of characters, from the simple fact of the hetero chronic variability of the ontogenetic stages, it fol lows that the latter can be modified individually, and that the re-modelling of one stage by no means necessarily entails that of the others. It cannot however be doubted that variability, from whatever cause it may have arisen, is in all cases competent to produce a new form. From the continued crossing of variable individuals alone, an equalization of differences must at length take place, and with this a new, although not always a widely deviating, constant form must arise.

Available in PDF, EPUB and Kindle. Book excerpt: This early work by Alfred Russel Wallace was originally published in 1916 and we are now republishing it with a brand new introductory biography. 'Alfred Russel Wallace: Letters and Reminiscences, Vol. 1.' is a collection of correspondence between Wallace and other scientists, including Herbert Spencer. Alfred Russel Wallace was born on 8th January 1823 in the village of Llanbadoc, in Monmouthshire, Wales. Wallace was inspired by the travelling naturalists of the day and decided to begin his exploration career collecting specimens in the Amazon rainforest. He explored the Rio Negra for four years, making notes on the peoples and languages he encountered as well as the geography, flora, and fauna. While travelling, Wallace refined his thoughts about evolution and in 1858 he outlined his theory of natural selection in an article he sent to Charles Darwin. Wallace made a huge contribution to the natural sciences and he will continue to be remembered as one of the key figures in the development of evolutionary theory.

Excerpt: ...in Triton we have reversion to an older phyletic stage.23 '1 See also Lubbock " On the Origin and Metamorphoses of Insects," London, 1874. In 2' See the first essay " On the Seasonal Dimorphism of Butterflies," p. 82. " Eng. ed. It has frequently been objected to me that the existing Axolotl is not a form resulting from atavism, but a case of " arrested growth." The expression "atavism" is certainly to be here taken in a somewhat different sense than, for example, in the case of the reversion of the existing Axolotl to the Amblystoma form. Further on, I have myself insisted that in the first case the phyletic stage in which the reversion occurred is still completely preserved in the ontogeny of each individual, whilst the Amblystoma. stage has become lost in the ontogeny of the Axolotl. If, therefore, we apply the term " atavism" only to I cannot agree with my friend Professor Haeckel when he occasionally designates the reversion of such characters or stages (i. e. complexes of characters) as are no longer preserved in the ontogeny, we cannot thus designate the present arrest of the Axolotl at the perennibranchiate stage. Such a restriction of the word, however, appears to me but little desirable, since the process is identical in both cases, i. e'. it depends upon the same law of heredity, in accordance with which a condition formerly occurring as a phyletic stage suddenly reappears through purely internal processes. It is true that the reversion is not complete, i. e. the present sexually mature Axolotl does not correspond in all details with its perennibranchiate ancestors. Since Wiedersheim has shown that the existing Axolotl possesses an intermaxillary gland, ...

Download or read book On the Origin of Species Annotated First Edition written by Charles Darwin and published by . This book was released on 2020-08-16 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first edition of Charles Darwin's On the Origin of Species, published on November 24, 1859 in London by John Murray. It is a seminal work in scientific literature and a landmark work in evolutionary biology. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. The starting chapters introduce the theory of natural selection, explaining why certain species thrive, while others decrease in number, how the members of nature are in competition with each other and why organisms tend to vary and change with time. Much of this work is based on experiments and observations seen within domestic animals and plants. The later chapters defend the theory of natural selection against apparent inconsistencies, why geological records are incomplete, why we find species so widespread and how sterility can be inherited when the organisation is unable to reproduce and more. The book is approachable for any audience.
