190344335Jena Gustav Fischer 1903. Lex8vo. Fine contemp. hcloth. spine gilt and with gilt lettering. 668 pp. textfigs. Internally clean and fine. <br/><br/><em>First edition of a groundbreaking work in genetics in which Johannsen introduces the concept of "pure line". Johannsen's work is dedicated to Francis Galton "the creator of the exact science of heredity". Johannsen was the first to attribute to mutation the origin of the small differences in the continous kind of variability characteristic of normal heredity."Yet Johannsen had shown that Galton's "law of regression" was wrong when applied as Galton had done - to impure or mixed populations. He proved that selection was ineffective - that is regression to parental averages was complete - only in the offspring derived by self-fertilization from a single parent as in peas beans and other "selfers." The offspings and descendants from such a plant Johannsen referred to as a "pure line". His theory was that offspring of a pure line were genetically identical and that fluctuating variability among such offspring was due to effects of change and enviromental factors. These effects were not heritable and hence were not subject to the action of selection either natural or artificial."DSB VII p. 114.Garrison & Morton No. 242. </em> hardcover

Baur Was Last A Professor At The University Of Chicago 1892 -1898. Baur Wrote Extensively On Various Paleontological Topics. He Also Built On The Late Nineteenth Century Theory Of Evolution And Wrote Extensively On His Idea That Changes In Morphology Might Be Brought Out By A Change In Environment Including Nutrition Etc. Such That These Changed Characteristics Would Persist In Successive Generations So Long As The Changed Conditions Persisted For Which There Is Now Some Evidence For At Least Three Generations. He Cited Extensively To Personal Observations And Reports From Others. His Work Differs From Weizmann Etc. In That He Maintained That Changes In Environment Could Bring Out Changes In Morphology Without Changes In The Genetic Material Such Changes Persisting In Successive Generations When The Environmental Changes Also Persisted. In One Such 1891 Paper He Concludes With A Citation To Darwin's Letter To Wagner: "In My Opinion The Greatest Error Which I Have Committed Has Been Not Allowing Sufficient Weight To The Direct Action Of The Environment - I.E. Food Climate Etc. -Independently Of Natural Selection." Although Now Dismissed Some Because Of His Neo-Lamarckian Ideas His Departures From Rigorous Scientific Evidence In Genetics Is Perhaps Less Serious Than The Acceptance And Promotion Of The Ideas Of "Phlogiston" By Important Earlier Chemists And Of "Ether" By His Contemporaries Among Important Physicists; And The Emphasis Of The Neo-Lamarckians On Environmental Nutritional And Physiological Factors Is More In Keeping With Modern Understanding Of Individual Development Than The Emphasis Upon Purely Genetic Evolution Which Treats Only Classes Of Individuals By Arbitrary Groupings Into Classes Of Individuals . Complete Collections Of Original Manuscripts And Scientific Offprints From This Period Are Increasingly Uncommon In The Market.

Near Fine With Just A Trace Of Rubbing At Corners And On Spine Gilt Brilliant Cloth And Contents Immaculate. A Classic Of Semi-Science First Published In Italy In 1906 This Being The First Edition In English. Per Wikipedia: Eugenio Vittorio Rignano 1870 In Livorno - 1930 Was A Jewish Italian Philosopher. He Was Born In Livorno To Giacomo Rignano And Fortunata Tedesco Into A Jewish Family. Rignano Edited The Journal Rivista Di Scienza Later Known As Scientia It. His Book The Psychology Of Reasoning 1923 Influenced The Social Anthropologist Edward Evans-Pritchard. His Book Man Not A Machine 1926 Was Replied To By Joseph Needham's Man A Machine 1927. Rignano Took Interest In Biology And Wrote A Book That Argued For The Inheritance Of Acquired Characteristics. He Advanced A Moderated Lamarckian Hypothesis Of Inheritance Known As "Centro-Epigenesis". His Views Were Controversial And Not Accepted By Most In The Scientific Community. His Book The Nature Of Life 1930 Was Described In A Review As Presenting A "Militant At Times Almost An Evangelical Exposition And Defense Of An Energetic Vitalism." However Historian Peter J. Bowler Has Written That Rignano Rejected Both Materialism And Vitalism And Adopted A Similar Position To What Was Known As Emergent Evolution. Li Dazhao One Of The Founders Of The China Communist Party Was An Avid Reader Of Rignano's Works And Chinese Communist Emphasis On Absolute Control Of All Conduct May Be Influenced By The Belief That It Will Result In Changed Behavior Forever In Future Generations Their Stated Goal. . Rignano's Views On Acquired Characteristics And Organic Memory Are Discussed In Detail By Historian Laura Otis And Psychologist Daniel Schacter. The Finding That The Immune System Does Indeed Acquire Inheritable Characteristics Puts Much Of The Lamarckian Debate Into A New And Politically Distressing Light. <br/> <br/> The Open Court Publishing Co hardcover
