Schltdl.
Diederich Franz Leonhard von Schlechtendal (27 November 1794, Xanten – 12 October 1866, Halle an der Saale, Halle) was a German botanist. Life and work Von Schlechtendal was born in Xanten, Xanten am Rhein and when his father Diederich Friedrich Carl von Schlechtendal (1767-1842) became a court judge. His mother Katharina Margarete Schlechtendal, née Bartels died when he was just three. His father lost his job when the French occupied the left bank of the Rhine and the family moved to Berlin. Contact with Carl Ludwig Willdenow, Carl Willdenow made him interested in botany at an early age. He went to the gymnasium in Berlin and then in a monastery school before joining voluntary military service in Breslau. He was dismissed for being physically unfit and he returned to Berlin to study botany. In 1813 he attended lectures in botany and medicine under Christoph Wilhelm Hufeland (1762-1836), Carl August Wilhelm Berends, Karl August Berends (1795-1826), and Karl Ferdinand von Gr ...

Kurt Polycarp Joachim Sprengel
Kurt Polycarp Joachim Sprengel (3 August 1766 – 15 March 1833) was a German botanist and physician who published an influential multivolume history of medicine, ''Versuch einer pragmatischen Geschichte der Arzneikunde'' (1792–99 in four volumes with later editions running to five) and several other medical reference works. Biography Sprengel was born at Boldekow in Pomerania, and he is considered of German nationality.

Christian Gottfried Daniel Nees Von Esenbeck
Christian Gottfried Daniel Nees von Esenbeck (14 February 1776 – 16 March 1858) was a prolific Germany, German botanist, physician, zoologist, and natural philosopher. He was a contemporary of Goethe and was born within the lifetime of Carl Linnaeus, Linnaeus. He described approximately 7,000 plant species (almost as many as Linnaeus himself). His last official act as president of the German Academy of Natural Scientists Leopoldina was to admit Charles Darwin as a member. He was the author of numerous monographs on botany and zoology and majority of his best-known works deal with fungi. Biography Nees von Esenbeck was born in Schloss Reichenberg near Reichelsheim (Odenwald) in Hesse, Germany. He showed an early interest in science and, after receiving his primary education in Darmstadt, went on to the University of Jena and obtained his degree in biology (natural history) and medicine in 1800.

Common Descent
Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population. The more recent the ancestral population two species have in common, the more closely they are related. The most recent common ancestor of all currently living organisms is the last universal ancestor, which lived about 3.9 billion years ago. The two earliest pieces of evidence for life on Earth are graphite found to be biogenic in 3.7 billion-year-old metasedimentary rocks discovered in western Greenland and microbial mat fossils found in 3.48 billion-year-old sandstone discovered in Western Australia. All currently living organisms on Earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution
Evolution is the change in the heritable Phenotypic trait, characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) phenotypic variatio ...

Darwinism
''Darwinism'' is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce. Also called ''Darwinian theory'', it originally included the broad concepts of transmutation of species or of evolution which gained general scientific acceptance after Darwin published ''On the Origin of Species'' in 1859, including concepts which predated Darwin's theories. English biologist Thomas Henry Huxley coined the term ''Darwinism'' in April 1860. Terminology ''Darwinism'' subsequently referred to the specific concepts of natural selection, the Weismann barrier, or the central dogma of molecular biology. Though the term usually refers strictly to biological evolution, creationists have appropriated it to refer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferdinand Deppe
Paul Ferdinand Deppe known mostly as Ferdinand Deppe (20 October 1795 – 3 February 1861) was a German naturalist, explorer and painter. He was the younger brother of Wilhelm Deppe, an accountant with the Berlin Zoological Museum. A number of species have been described from his collected and named after him. Life and work Deppe was born in Berlin. He worked at the Royal Gardens but was connected to the Zoological Museum in Berlin where his brother Wilhelm was accountant. He was selected to accompany Count von Sack to Mexico in 1824. He studied English, Spanish and trained in the preparation of natural history specimens before leaving. He left Berlin in August 1824 and after changes of ships at London and Jamaica, reached Alvarado, Veracruz in December. He collected specimens of invertebrates as well as vertebrates. These specimens were purchased by Hinrich Lichtenstein and he then decided to make another trip to Mexico with botanist Wilhelm Schiede (1798-1836) with the plan ...

Christian Julius Wilhelm Schiede
Christian Julius Wilhelm Schiede (February 3, 1798 – December 1836) was a German physician and botanist born in Kassel. He studied natural sciences and medicine in Berlin and Göttingen, where he earned his doctorate in 1825. Afterwards he practiced medicine in Kassel. In 1828 Schiede emigrated to Mexico, accompanied by Ferdinand Deppe (1794-1861), a German naturalist with previous experience in the country. The two scientists planned to collect zoological and botanical specimens, which would then be sold to museums and dealers in Europe. In July 1828 they settled in Xalapa, Veracruz, Jalapa, and performed scientific excursions throughout the state of Veracruz. Although they were able sell their collections to museums in Berlin and Vienna, the money earned was insufficient to continue operations, causing Deppe and Schiede to abandon their enterprise in late 1830. Christian Schiede died in Mexico in 1836 at the age of 38. The botanical genera ''Taxonomy of the Orchidaceae, Sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora (plants)
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) ...
