Maynard Mayo Metcalf
Maynard Mayo Metcalf (12 March 1868 – 19 April 1940) was an American biologist and a professor of zoology at Johns Hopkins University. He was the only biologist who was allowed to testify in the Scopes Trial. Metcalf specialized in protozoal parasites which he examined in a wide range of hosts and was especially interested in the Opalinidae. Life and work Metcalf was born in Elyria, Ohio to Eliab Wight and Eliza Mary (Ely) Metcalf. The family was of English ancestry and an early settler had been a tapestry manufacturer. He was educated at Oberlin College, receiving a BA (1889) and later a ScD (1914). His doctoral research (1893) was at Johns Hopkins University under W. K. Brooks. He then taught at the Goucher Women's College until 1906 after which he joined Oberlin College. He spent two years in Europe, first at Wurzburg with Theodor Boveri, then in Berlin followed by some time at the Naples Biological Station. He left Oberlin in 1914 and began private research at La Jolla, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stazione Zoologica Anton Dohrn
The Stazione Zoologica Anton Dohrn is a research institute in Naples, Italy, devoted to basic research in biology. Research is largely interdisciplinary involving the fields of evolution, biochemistry, molecular biology, neurobiology, cell biology, biological oceanography, marine botany, molecular plant biology, benthic ecology, and ecophysiology. Founded in 1872 as a private concern by Anton Dohrn, in 1982 the Stazione Zoologica came under the supervision and control of the Ministero dell'Università e della Ricerca Scientifica e Tecnologica (Ministry of Universities and Scientific and Technological Research) as a National Institute. History The idea Dohrn's idea was to establish an international scientific community provided with laboratory space, equipment, research material and a library. This was supported and funded by the German Government, Thomas Henry Huxley, Charles Darwin, Francis Balfour and Charles Lyell among others. Dohrn provided a substantial sum himself. Ru ...

1940 Deaths
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus and Decimus Clodius Septimius Albinus Caesar become Roman Consuls. * Battle of Issus: Septimius Severus marches with his army (12 legions) to Cilicia, and defeats Pescennius Niger, Roman governor of Syria. Pescennius retreats to Antioch, and is executed by Severus' troops. * Septimius Severus besieges Byzantium (194–196); the city walls suffer extensive damage.

William Diller Matthew
William Diller Matthew Royal Society, FRS (February 19, 1871 – September 24, 1930) was a vertebrate paleontologist who worked primarily on mammal fossils, although he also published a few early papers on mineralogy, petrological geology, one on botany, one on trilobites, and he described ''Tetraceratops insignis'', which was much later suggested to be the oldest known (Cisuralian, Early Permian) therapsid. Matthew was born in Saint John, New Brunswick, Saint John, New Brunswick, the son of George Frederic Matthew and Katherine (Diller) Matthew. His father was an amateur geologist and paleontologist who instilled his son with an abiding interest in the earth sciences. Matthew received an A.B. at the University of New Brunswick in 1889 and then earned his Ph.D. at Columbia University in 1894. Matthew was curator of the American Museum of Natural History from the mid-1890s to 1927, and director of the University of California Museum of Paleontology from 1927 to 1930. He was the fat ...

Orthogenesis
Orthogenesis, also known as orthogenetic evolution, progressive evolution, evolutionary progress, or progressionism, is an obsolete biological hypothesis that organisms have an innate tendency to evolve in a definite direction towards some goal (teleology) due to some internal mechanism or "driving force". According to the theory, the largest-scale trends in evolution have an absolute goal such as increasing biological complexity. Prominent historical figures who have championed some form of evolutionary progress include Jean-Baptiste Lamarck, Pierre Teilhard de Chardin, and Henri Bergson. The term ''orthogenesis'' was introduced by Wilhelm Haacke in 1893 and popularized by Theodor Eimer five years later. Proponents of orthogenesis had rejected the theory of natural selection as the organizing mechanism in evolution for a rectilinear model of directed evolution. With the emergence of the modern synthesis, in which genetics was integrated with evolution, orthogenesis and othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salp
A salp (plural salps, also known colloquially as “sea grape”) or salpa (plural salpae or salpas) is a barrel-shaped, planktic tunicate. It moves by contracting, thereby pumping water through its gelatinous body, one of the most efficient examples of jet propulsion in the animal kingdom. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton. Distribution Salps are common in equatorial, temperate, and cold seas, where they can be seen at the surface, singly or in long, stringy colonies. The most abundant concentrations of salps are in the Southern Ocean (near Antarctica), where they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. Since 1910, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing. Salps have been seen in increasing numbers along the coast of Washington. Life cycle Salps have a complex life cycle, with an obligatory a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodor Boveri
Theodor Heinrich Boveri (12 October 1862 – 15 October 1915) was a German zoologist, comparative anatomist and co-founder of modern cytology. He was notable for the first hypothesis regarding cellular processes that cause cancer, and for describing ''chromatin diminution in nematodes''. Boveri was married to the American biologist Marcella O'Grady (1863–1950). Their daughter Margret Boveri (1900–1975) became one of the best-known journalists in post-World War II Germany. Work Using an optical microscope, Boveri examined the processes involved in the fertilization of the animal egg cell; his favorite research objects were the nematode ''Parascaris'' and sea urchins. Boveri's work with sea urchins showed that it was necessary to have all chromosomes present in order for proper embryonic development to take place. This discovery was an important part of the Boveri–Sutton chromosome theory. He also discovered, in 1888, the importance of the centrosome for the formation of th ...

William Keith Brooks
William Keith Brooks (March 25, 1848 – November 12, 1908) was an American zoologist, born in Cleveland, Ohio, March 25, 1848. Brooks studied embryological development in invertebrates and founded a marine biological laboratory where he and others studied heredity. His best known book, ''The Oyster'', was first published in 1891 and has been reprinted many times. Brooks was proficient in many subjects, including Greek and biology, and as a young man was unsure where he wished to focus his studies. He spent two years at Hobart College before settling on biology, and then transferred to Williams College, where he received his BA in 1870. He then entered Harvard and studied under Louis Agassiz, receiving his PhD in 1875. A year later he became a junior faculty member at Johns Hopkins University when it opened, teaching and researching marine biology. After marrying Amelia Katherine Schultz in 1878, Brooks founded the Chesapeake Zoological Laboratory. He spent most summers ...
