Excerpt from The Relative Value of the Processes Causing Evolution
But at times the feeling will not down, that a great number of eminent and able Biologists utterly fail to understand in how far their results have value in themselves, and in how far they are but building-stones. Many do not seem to see, that, without a timely attempt to utilize their results in construct ing a coherent whole of a higher order much detail is utterly wasted, being without significance in itself. It is very evident that many fail to see the forest because of all the trees.
There is no real spirit of subordination of the different genet ical investigations to the main problems of evolution, in the work of any but Bateson and a few others. What we need from time to time, is to pause, and try to see' what all the others are doing, where they are going, what work is left undone, and where work is unnecessarily duplicated.

Excerpt from The Relative Value of the Processes Causing Evolution
The origin of species, the way in which evolution has taken place and is still progressing, seems, even now, to remain an open question. So much so, that three absolutely diverse theories of evolution still find their adherents. These three main theories are so different, that it would seem as if the real nature of the process of species-formation must for ever remain a subject for speculation only, and as if good facts are wholly wanting.
A minority of Biologists adhere to Lamarck's theory of the inheritance of adaptative changes induced by the environment; some incline to the view of Darwin and Weismann, that natural selection on small, individual variations gradually changes species, and still others believe with de Vries, that new species spring into being spontaneously, by mutation, saltation. Judging from this diversity of opinion, it would certainly seem as if no important headway had been made since Darwin.
This is very surprising, when we see how in the last fifteen years Genetics has become established as an actively developing branch of science, and counts by hundreds the Biologists who are engaged in genetical experimental investigations. All the data thus acquired, should have their significance for an insight into the process of evolution, the origin of species. This reluctance on the part of Biologists in general, and of Geneticists specially, to make an attempt to correlate the facts so far obtained, and to find out whether they shed any new light on the problem how new species may originate, is caused mainly, we hope, by the very diversity of the three above-named evolution-theories.

The Relative Value of the Processes Causing Evolution (Classic Reprint)
Print-on-DemandAnbieter: Forgotten Books, London, Vereinigtes Königreich
Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book examines the intricate relationship between heredity, variation, and evolution. The author explores the evolution of scientific thought on this subject, from the theories of Lamarck and Darwin through to the later discoveries of Mendel and Johannsen. The book takes a unique approach, challenging the dominant theories of the day and emphasizing the need for a deeper understanding of the underlying mechanisms of inheritance and the influence of environment on evolution. Through a combination of historical analysis and a thorough consideration of experimental evidence, the author presents a groundbreaking perspective on the complex interplay of factors that drive the development of new species. The book offers a compelling case for a more nuanced understanding of evolution, one that moves beyond simplistic explanations and embraces the intricate nature of genetic processes. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781331917700_0
