Their paper built upon Ernst Mayr's theory of geographic speciation, I. Michael Lerner's theories of developmental and genetic homeostasis, as well as their own empirical research.

Punctuated equilibrium originated as a logical extension of Ernst Mayr's concept of genetic revolutions by allopatric and especially peripatric speciation as applied to the fossil record.

A year before their 1972 Eldredge and Gould paper, Niles Eldredge published a paper in the journal Evolution which suggested that gradual evolution was seldom seen in the fossil record and argued that Ernst Mayr's standard mechanism of allopatric speciation might suggest a possible resolution.

Where Simpson relied upon a synergistic interaction between genetic drift and a shift in the adaptive fitness landscape, Eldredge and Gould relied upon ordinary speciation, particularly Ernst Mayr's concept of allopatric speciation.

April to August 1939 was spent at the California Academy of Sciences and at Ernst Mayr's home in New Jersey.

Ernst Mayr's opinion was even more clear-cut:

Organised by Hausmann, Grosz and Heartfield, along with Max Ernst, the fair was to become the most famous of all Berlin Dada's exploits, featuring almost 200 works by artists including Francis Picabia, Hans Arp, Ernst, Otto Dix & Rudolf Schlichter, as well as key works by Grosz, Höch and Hausmann.

The exhibition also proved to be one of the main influences on the content and layout of Entartete Kunst, the show of degenerate art put on by the Nazis in 1937, with key slogans such as ' Nehmen Sie DADA Ernst ' ( Take Dada seriously!

While Keirsey's main strength may be his accuracy regarding differences in overt behavior, perhaps his most important contribution is his synthesis of Myers ' model of " sixteen types " with Ernst Kretschmer's model of four " temperament types ," which Keirsey traces back to Greek mythology.

Ernst Fuchs ( 14 June 1851, Kritzendorf – November 21, 1930, Vienna ) was an Austrian ophthalmologist and physician best known for his contribution to description and identification of Fuchs heterochromic iridocyclitis ( FHI ) in 1906, Fuchs's dystrophy, and his contributions in the field of ophthalmology including but not limited to Fuchs spot.

The German philosopher Ernst Bloch attempted to reveal what he considered the hidden metaphysical meaning of Marx's thought, which Leszek Kołakowski summarizes as, " a picture of the world tending towards a universal synthesis of all forces and factors, not only social phenomena but the cosmos as a whole.

Ernst Mayr judged him to be the most important evolutionary thinker between Darwin and the evolutionary synthesis around 1930 – 40, and was " one of the great biologists of all time ".

Ernst Haeckel ( 1866 ), in his endeavour to produce a synthesis of Darwin's theory with Lamarckism and Naturphilosophie, proposed that " ontogeny recapitulates phylogeny ," that is, the development of the embryo of every species ( ontogeny ) fully repeats the evolutionary development of that species ( phylogeny ), in Geoffroy's linear model rather than Darwin's idea of branching evolution.

* Huxley's main co-respondents in the modern evolutionary synthesis are usually listed as Ernst Mayr, Theodosius Dobzhansky, George Gaylord Simpson, Bernhard Rensch, Ledyard Stebbins and the population geneticists J. B. S.

Still, Ernst Mayr, co-founder of the modern evolutionary synthesis and a critic of both vitalism and reductionism, writing in 2002 after the mathematical development of theories underlying emergent behavior, stated:

Ernst Mayr, George Gaylord Simpson and G. Ledyard Stebbins were also important discipline-builders during the modern synthesis, in the fields of systematics, paleontology and botany, respectively.

Following the rediscovery of Mendel's principles of genetics, several theorists such as RA Fisher, JBS Haldane, Sewall Wright, Ernst Mayr and Theodosius Dobzhansky contributed to the synthesis of Mendel and Darwin's concept of natural selection.

According to Tamir Bar-On, the arguments and the positions of the Nouvelle Droite can not be easily positioned in the traditional Left-Right dichotomy, noting that it is some sort of ideological synthesis of ideas of the Weimar Revolutionary Right ( such as Carl Schmitt, Oswald Spengler and Ernst Jünger ) and the New Left.

His work in this area would influence Ernst Mayr, who was also an assistant at the museum from 1927 – 1930, and would contribute to the development of the modern evolutionary synthesis.

The axiom of choice was formulated in 1904 by Ernst Zermelo in order to formalize his proof of the well-ordering theorem.

This work resumed however with the development of the so-called " Second Quest ", among whose notable exponents was Rudolf Bultmann's student Ernst Käsemann.

Since this picture was first developed by Ernst Stueckelberg, and acquired its modern form in Feynman's work, it is called the Feynman-Stueckelberg interpretation of antiparticles to honor both scientists.

Arnulf was, according to most sources, the illegitimate son of Carloman, King of Bavaria, and his concubine Liutswind, perhaps of Carantanian origin, and possibly the sister of Ernst, Count of the Bavarian Nordgau Margraviate in the area of the Upper Palatinate, or perhaps the burgrave of Passau, as some sources say.

The ratio of the flow speed to the speed of sound was named the Mach number after Ernst Mach, who was one of the first to investigate the properties of supersonic flow which included Schlieren photography techniques to visualize the changes in density.

* Ansbach was the birthplace of the early chemist, Georg Ernst Stahl.

Many artists, including Martin Schongauer, Hieronymus Bosch, Dorothea Tanning, Max Ernst, and Salvador Dalí, have depicted these incidents from the life of Anthony ; in prose, the tale was retold and embellished by Gustave Flaubert in The Temptation of Saint Anthony.

It was the Bauhaus contemporaries Bruno Taut, Hans Poelzig and particularly Ernst May, as the city architects of Berlin, Dresden and Frankfurt respectively, who are rightfully credited with the thousands of socially progressive housing units built in Weimar Germany.

In 1911, B. thuringiensis was rediscovered in Germany by Ernst Berliner, who isolated it as the cause of a disease called Schlaffsucht in flour moth caterpillars.

Another theorist, Ernst Volckheim, was also used by Guderian, and wrote a huge amount on tank and combined arms tactics, and is not acknowledged by Guderian.

The Achaemenid collection was enhanced with the addition of the Oxus Treasure in 1897, by acquisition from the German scholar Ernst Herzfeld, and then by the work of Sir Aurel Stein.

A contrasting position was taken by Ernst Mach, who contended that all motion was relative.

The first attempt at a microscopic description of magnetism was by Wilhelm Lenz and Ernst Ising through the Ising model that described magnetic materials as consisting of a periodic lattice of quantum spins that collectively acquired magnetization.

This was in contradiction to Ernst Haeckel's theory that the complete phylogeny of a species would be repeated during embryonic development, including generation of the first nucleated cell from a " Monerula ", a structureless mass of primordial mucus (" Urschleim ").

Ernst Mayr remarks that the theory was hotly contested by some famous geneticists: William Bateson, Wilhelm Johannsen, Richard Goldschmidt and T. H.

Renowned Arthurian scholar Ernst Brugger suggested that it was a corruption of Camlann, the site of Arthur's final battle in Welsh tradition.

Ernst Walter Mayr ( July 5, 1904 – February 3, 2005 ) was one of the 20th century's leading evolutionary biologists.

Through such people as Nikola Tesla, Galileo Ferraris, Oliver Heaviside, Thomas Edison, Ottó Bláthy, Ányos Jedlik, Sir Charles Parsons, Joseph Swan, George Westinghouse, Ernst Werner von Siemens, Alexander Graham Bell and Lord Kelvin, electricity was turned from a scientific curiosity into an essential tool for modern life, becoming a driving force for the Second Industrial Revolution.

The word " ecology " (" Ökologie ") was coined in 1866 by the German scientist Ernst Haeckel ( 1834 – 1919 ).

The term " ecology " () is of a more recent origin and was first coined by the German biologist Ernst Haeckel in his book Generelle Morphologie der Organismen ( 1866 ).
