The 1890s and the first decades of the twentieth century saw a vigorous debate about the mechanisms of evolutionary change. On one side, August Weismann defended the selectionist hypothesis; on the other, Herbert Spencer defended neo-Lamarckian theory. Supporters of Spencer, notably the American paleontologist and evolutionary theorist Henry Fairfield Osborn, recognized that the questions raised by Weismann and Spencer could only be settled experimentally. They called for the application of… Expand
The Case of Paul Kammerer: Evolution and Experimentation in the Early 20th Century
The Viennese zoologist Paul Kammerer (1880–1926) remains one of the most controversial scientists of the early 20th century, and his work is reconsidered in light of turn-of-the-century problems in evolutionary theory and experimental methodology. Expand
When exploring the relationship between two reputedly competitive scientific concepts that have persisted, with modification, through time, there are three main features to consider. First, there areExpand
Darwinism in the Twentieth Century: Productive Encounters with Saltation, Acquired Characteristics, and Development
Darwinism is one of several research traditions in evolutionary biology. I identify it, both before and after its unification with genetics, with Darwin’s theory of descent by natural selection fromExpand

The essentialism story is a version of the history of biological classification that was fabricated between 1953 and 1968 by Ernst Mayr, who combined contributions from Arthur Cain and David HullExpand
Alternatives to Darwinism in the Early Twentieth Century
Julian Huxley claimed that the period around 1900 experienced an ‘eclipse of Darwinism’ when natural selection was rejected in favour of alternative mechanisms of evolution. These included theExpand
Rethinking heredity, again.
It is shown that the concept of soft inheritance rejected by 20th-century genetics differs fundamentally from the current concept of 'nongenetic inheritance', and whereas it has long been assumed that heredity is mediated by a single, universal mechanism, a pluralistic model of heredITY is now emerging, based on a recognition of multiple, parallel mechanisms of inheritance.

The Spoiler: Paul Kammerer’s Fight for the Inheritance of Acquired Characteristics
In scientific controversy, as in sports, there are winners and losers, but sometimes also spoilers—unheralded outsiders, who defy convention and change the terms, the style, and the outcome of theExpand
A Unified Approach to the Evolutionary Consequences of Genetic and Nongenetic Inheritance
A unified theoretical framework based on the Price equation is proposed that can be used to model evolution under an expanded inheritance concept that combines the effects of genetic and nongenetic inheritance and can be applied to a variety of scenarios. Expand
Concept Genetic = Heritable ( Genetic = DNA )
Implicit in this, and many other writings, is the equivalence between the term “genetic” and those signals encoded by DNA sequences. How did we get to this peculiar definition of the term “genetic,”Expand
Environmentally alterable additive genetic effects
Environmentally alterable additive genetic effects place molecular epigenetic effects and soft inheritance within a modern neo-Darwinian quantitative genetic framework. Expand


From the Greeks to Darwin: an Outline of the Development of the Evolution Idea
THE object of this most interesting and useful work is to survey the last twenty-four centuries and bring together the thoughts—true and false—upon evolution. Examining and comparing the materialExpand
The Hereditary Mechanism and the Search for the Unknown Factors of Evolution
"Disprove Lamarck's principle and we must assume that there is some third factor in Evolution of which we are now ignorant."2 Chief among the unknown factors of evolution are the relations whichExpand

IN this, the first part of a paper on reversion, the two following questions are dealt with, viz.: (1) Is there invariably evidence of reversion? (2) May reversion, when it does occur, result in theExpand
The Modern Evolutionary Theory
Of all of Darwin's evolutionary theories, the one that encountered the greatest resistance, and was therefore the last one to be accepted, was the theory of natural selection. It was only about 1940Expand

In the 73 years since he wrote, there have been three published univariate statistical reanalyses of his data, emphasizing improvements on Bumpus' statistical methodology and his general conclusions on stabilizing selection are frequently cited in textbooks on evolution and population genetics.
