1923

A. E. Boycott and C. Diver describe "delayed" Mendelian inheritance controlling the direction of the coiling of the shell in the snail Limnea peregra. A. H. Sturtevant suggests that the direction of coiling of the Limnea shell is determined by the character of the ooplasm, which is in turn controlled by the mother's genotype.

Jesuit priests Émile Lincent and Pierre Teilhard de Chardin discover ancient stone tools at Shuidonggou, China. Their discoveries resemble those of the Middle Paleolithic industry in Europe.

Hitler reorganizes the Nazi party and publishes volume one of Mein Kampf.

Ibn Saud of Najd conquers Hijaz and forms Saudi Arabia.

1925

Tennessee schoolteacher John Thomas Scopes is tried for teaching evolution in the famous "Scopes Monkey Trial." Two-time presidential candidate William Jennings Bryan leads the prosecution. Labor lawyer Clarence Darrow leads the defense and goads Bryan into declaring that humans are not mammals. The conviction will be overturned on a technicality, and the anti-evolution law will remain on the books for decades.

image A. H. Sturtevant analyzes the Bar-eye phenomenon in Drosophila and discovers position effect.

Francis Turville-Petre finds Galilee Man, the first fossil hominid discovered in Western Asia. The fossil will later be dated to more than 250,000 years old, and classified as neither modern Homo sapiens nor Neanderthal.

Raymond Dart publishes a description of the "Taung Child," a hominid child's skull from Africa. He classifies it as Australopithecus africanus and concludes that it's the missing link between humans and apes.

Kodak introduces its 35 mm Motion Picture Duplicating Film for duplicate negatives. Previously, motion picture studios used a second camera alongside the primary camera to create a duplicate negative.

Hirohito takes over the Japanese throne upon the death of his father, Yoshihito.

image Mussolini takes total control in Italy, banning all opposition.

1926

A. H. Sturtevant finds the first inversion in Drosophila.

Harvard geology professor William Morris Davis publishes a paper entitled The Value of Outrageous Geological Hypotheses warning against quick dismissal of new ideas. The paper will become famous.

1927

image Bernard O. Dodge initiates genetic studies on Neurospora.

image H. J. Muller reports the artificial induction of mutations in Drosophila by x-rays.

image J. B. S. Haldane suggests that the genes known to control certain coat colors in various rodents and carnivores may be evolutionarily homologous.

Excavations in Kent's Cavern in southern England turn up a fragment of a human upper jaw, roughly 43,000 years old. Arthur Keith will provisionally identify it as anatomically modern human, and this finding will be confirmed in a 2011 study.

Johns Hopkins University biologist Raymond Pearl publishes an article entitled "Why Lazy People Live the Longest." He will expand on this rate-of-living hypothesis in a book the next year, arguing that a faster rate of biochemical reactions leads to a shorter lifespan. This hypothesis is quickly dismissed and generally considered buncombe. Later, however, Donald Trump, the 45th president of the United States will be discovered to hold similar views.

image Frederick Griffith discovers type-transformation of pneumococci. This lays the foundation for the work of Avery, MacLeod, and McCarthy (1944).

image L. J. Stadler reports the artificial induction of mutations in maize, and demonstrates that the dose-frequency curve is linear.

In a letter to Science, Louise Sudbury states that fossil plants, Cycadeoidea Etrusca, were collected by Etruscans over 4,000 years ago.

In trying to piece together a Burgess Shale organism over 500 million years old, Danish zoologist K. L. Henriksen glues an Anomalocaris appendage to a Tuzoia carapace to make what he thinks is a reasonable looking shrimp-like animal. This mistaken interpretation will persist for years.

John Henry Pull, a postman and amateur archaeologist, finds fossil urchins in two separate Neolithic burial sites. His efforts to publish on his findings, however, will be thwarted due to his pedestrian background.

Estonian paleobiologist Alexander Audova publishes a paper rejecting racial senility as the cause of dinosaur extinction and instead pointing to environmental change.

ESP Quick Facts

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
