Boris Kozo-Polyansky
Boris Mikhailovich Kozo-Polyansky (; 20 January 1890 – 21 April 1957) was a Soviet and Russian botanist and evolutionary biologist, best known for his seminal work, ''Symbiogenesis: A New Principle of Evolution'', which was the first work to place the theory of symbiogenesis into a Darwinian evolutionary context, as well as one of the first to redefine cell theory. Life Boris Kozo-Polyansky was born in Ashgabat, which at the time was part of the Russian Empire. He relocated to Voronezh in his early youth.Prokhorov, A. M. (Aleksandr Mikhaĭlovich). Great Soviet Encyclopedia. New York: Macmillan, 1973. He graduated from Moscow University in 1914 at the age of 24, before returning to Voronezh where he worked as an assistant at Voronezh Agricultural University until 1918. In 1920 he then became a professor at Voronezh State University, where he taught for the remainder of his life and served as a Dean, Chair of Botany and Vice President of the University. He is buried in Voronezh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashgabat
Ashgabat or Asgabat ( tk, Aşgabat, ; fa, عشقآباد, translit='Ešqābād, formerly named Poltoratsk ( rus, Полтора́цк, p=pəltɐˈratsk) between 1919 and 1927), is the capital and the largest city of Turkmenistan. It lies between the Karakum Desert and the Kopetdag mountain range in Central Asia, near the Iran-Turkmenistan border. The city was founded in 1881 on the basis of an Ahal Teke tribal village, and made the capital of the Turkmen Soviet Socialist Republic in 1924. Much of the city was destroyed by the 1948 Ashgabat earthquake, but has since been extensively rebuilt under the rule of Saparmurat Niyazov's "White City" urban renewal project, resulting in monumental projects sheathed in costly white marble. The Soviet-era Karakum Canal runs through the city, carrying waters from the Amu Darya from east to west. Since 2019, the city has been recognized as having one of the highest costs of living in the world largely due to Turkmenistan's inflation ...

Prokaryote
A prokaryote () is a single-celled organism that lacks a nucleus and other membrane-bound organelles. The word ''prokaryote'' comes from the Greek πρό (, 'before') and κάρυον (, 'nut' or 'kernel').Campbell, N. "Biology:Concepts & Connections". Pearson Education. San Francisco: 2003. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota. But in the three-domain system, based upon molecular analysis, prokaryotes are divided into two domains: ''Bacteria'' (formerly Eubacteria) and ''Archaea'' (formerly Archaebacteria). Organisms with nuclei are placed in a third domain, Eukaryota. In the study of the origins of life, prokaryotes are thought to have arisen before eukaryotes. Besides the absence of a nucleus, prokaryotes also lack mitochondria, or most of the other membrane-bound organelles that characterize the eukaryotic cell. It was once thought that prokaryotic cellular components within the cytop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Lenin
The Order of Lenin (russian: Орден Ленина, Orden Lenina, ), named after the leader of the Russian October Revolution, was established by the Central Executive Committee on April 6, 1930. The order was the highest civilian decoration bestowed by the Soviet Union. The order was awarded to: * Civilians for outstanding services rendered to the State * Members of the armed forces for exemplary service * Those who promoted friendship and cooperation between people and in strengthening peace * Those with meritorious services to the Soviet state and society From 1944 to 1957, before the institution of a specific length of service medals, the Order of Lenin was also used to reward 25 years of conspicuous military service. Those who were awarded the titles "Hero of the Soviet Union" and " Hero of Socialist Labour" were also given the order as part of the award. It was also bestowed on cities, companies, factories, regions, military units, and ships. Various educational instituti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The New Principle Of Biology- An Essay On The Theory Of Symbiogenesis
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Armen Takhtajan
Armen Leonovich Takhtajan or Takhtajian ( hy, Արմեն Լևոնի Թախտաջյան; russian: Армен Леонович Тахтаджян; surname also transliterated Takhtadjan, Takhtadzhi︠a︡n or Takhtadzhian, pronounced takh-tuh-JAHN; 10 June 1910 – 13 November 2009), was a Soviet-Armenian botanist, one of the most important figures in 20th century plant evolution and systematics and biogeography.

Lynn Margulis
Lynn Margulis (born Lynn Petra Alexander; March 5, 1938 – November 22, 2011) was an American evolutionary biologist, and was the primary modern proponent for the significance of symbiosis in evolution. Historian Jan Sapp has said that "Lynn Margulis's name is as synonymous with symbiosis as Charles Darwin's is with evolution." In particular, Margulis transformed and fundamentally framed current understanding of the evolution of cells with nuclei – an event Ernst Mayr called "perhaps the most important and dramatic event in the history of life" – by proposing it to have been the result of symbiotic mergers of bacteria. Margulis was also the co-developer of the Gaia hypothesis with the British chemist James Lovelock, proposing that the Earth functions as a single self-regulating system, and was the principal defender and promulgator of the five kingdom classification of Robert Whittaker. Throughout her career, Margulis' work could arouse intense objection (one grant applic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Punctuated Equilibrium
In evolutionary biology, punctuated equilibrium (also called punctuated equilibria) is a Scientific theory, theory that proposes that once a species appears in the fossil record, the population will become stable, showing little evolution, evolutionary change for most of its geological history. : ''Reprinted in'' * * This state of little or no morphological change is called ''stasis''. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and geologic time scale, geologically rapid events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another. Punctuated equilibrium is commonly contrasted with phyletic gradualism, the idea that evolution generally occurs uniformly by the steady and gradual transformation of whole lineages (anagenesis). In 1972, paleontologists Niles Eldredge and Stephen Jay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Konstantin Mereschkowski
Konstantin Sergeevich Mereschkowski ( rus, Константи́н Серге́евич Мережко́вский, p=mʲɪrʲɪˈʂkofskʲɪj; – 9 January 1921) was a prominent Russian biologist and botanist, active mainly around Kazan, Tatarstan, whose research on lichens led him to propose the theory of symbiogenesis – that larger, more complex cells (of eukaryotes) evolved from the symbiotic relationship between less complex ones. He presented this theory in 1910, in his work, ''The Theory of Two Plasms as the Basis of Symbiogenesis, a New Study of the Origins of Organisms'', although the fundamentals of the idea had already appeared in his earlier 1905 work, ''The nature and origins of chromatophores in the plant kingdom''. Biography Early life Konstantin was born in Saint Petersburg, one of six sons and three daughters in the Mereschkowski family. His father Sergey Ivanovich served as a senior official in several Russian local governors' cabinets (including tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andreas Franz Wilhelm Schimper
Andreas Franz Wilhelm Schimper (12 May 1856 – 9 September 1901) was a German botanist and phytogeographer who made major contributions in the fields of histology, ecology and plant geography. He travelled to South East Asia and the Caribbean as part of the 1899 deep-sea expedition. He coined the terms tropical rainforest and sclerophyll and is commemorated in numerous specific names. Biography Schimper was born in Strassburg, (present day Strasbourg, France), into a family of eminent scientists. His father Wilhelm Philippe Schimper (1808-1880) was Director of the Natural History Museum in the same town, Professor of Geology, and a leading bryologist. His father's cousin was Georg Wilhelm Schimper (1804-1878), prominent collector and explorer in Arabia and North Africa; the naturalist Karl Friedrich Schimper was also a relative. Schimper studied at the University of Strassburg from 1874 to 1878, acquiring a Ph.D. He then worked in Lyon, and in 1880 travelled to the United ...
