Genetic Assimilation and Canalisation in the Baldwin Effect
Get PDFThe Baldwin Effect indicates that individually learned behaviours acquired during an organism’s lifetime can influence the evolutionary path taken by a population, without any direct Lamarckian transfer of traits from phenotype to genotype. Several computational studies modelling this effect have included complications that restrict its applicability. Here we present a simplified model that is used to reveal the essential mechanisms and highlight several conceptual issues that have not been clearly defined in prior literature. In particular, we suggest that canalisation and genetic assimilation, often conflated in previous studies, are separate concepts and the former is actually not required for non-heritable phenotypic variation to guide genetic variation. Additionally, learning, often considered to be essential for the Baldwin Effect, can be replaced with a more general phenotypic plasticity model. These simplifications potentially permit the Baldwin Effect to operate in much more general circumstances

Letter from Roger Baldwin, Director, American Civil Liberties Union, to Homer L. Morris, American Friends Service Committee, March 1, 1943
No full textLetter from Roger Baldwin to Homer L. Morris, regarding funds being raised by the American Friends Service Committee to support attorney Frank L. Walters argument of Gordon Hirabayashi's case in the Supreme Court. Baldwin quotes Joseph Conard's letter (chs_ms3580_0196) warning of Walters' poor performance representing Hirabayashi in the Circuit Court of Appeals at San Francisco. Baldwin writes: "I should think it would be wise now, in the event of an adverse decision which is expected, to see that somebody else than Mr. Walters argues the case in the Supreme Court. We should be very glad to make recommendations if you wish."The ACLU-Northern California case file records contain legal documents and correspondence pertaining to the case Ex parte Mitsuye Endo (1944), in which the United States Supreme court unanimously ruled that the federal government could not indefinitely detain United States citizens who were loyal to the government. Files include documents related to the Gordon Hirabayashi Supreme Court case Hirabayashi v. United States
