Transmutation Of Species
Transmutation of species and transformism are unproven 18th and 19th-century evolutionary ideas about the change of one species into another that preceded Charles Darwin's theory of natural selection. The French ''Transformisme'' was a term used by Jean Baptiste Lamarck in 1809 for his theory, and other 18th and 19th century proponents of pre-Darwinian evolutionary ideas included Denis Diderot, Étienne Geoffroy Saint-Hilaire, Erasmus Darwin, Robert Grant, and Robert Chambers, the anonymous author of the book ''Vestiges of the Natural History of Creation''. Opposition in the scientific community to these early theories of evolution, led by influential scientists like the anatomists Georges Cuvier and Richard Owen, and the geologist Charles Lyell, was intense. The debate over them was an important stage in the history of evolutionary thought and influenced the subsequent reaction to Darwin's theory. Terminology Transmutation was one of the names commonly used for evolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Oracle Of Reason
''The Oracle of Reason, or Philosophy Vindicated'' was the first avowedly atheistic periodical to be published in Britain. It was founded by Charles Southwell, William Chilton and John Field in 1841, and lasted until 1843. Several of its editors were imprisoned for blasphemy. History The ''Oracle'' owed its origins to a split in Robert Owen's Universal Community Society. For the early background, see Charles Southwell. The first issue of the weekly ''Oracle'' was published on 6 November 1841 (price: 1 d), and the last issue was dated 2 December 1843. It was published 6 November 1841 to 8 January 1842, then there was a gap before publication resumed from 12 February 1842 to 2 December 1843.Royle 1974, p.321. According to Royle (1974, p. 74), it was "at first highly successful, selling on average about four thousand copies a week." The first editor of the ''Oracle'' was Charles Southwell. George Jacob Holyoake took over when Southwell was imprisoned, and when Holyoake was i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with Naturalism (philosophy), natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine.#Packard, Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French Nationa ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vapor
In physics, a vapor (American English) or vapour (British English and Canadian English; American and British English spelling differences#-our, -or, see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature,R. H. Petrucci, W. S. Harwood, and F. G. Herring, ''General Chemistry'', Prentice-Hall, 8th ed. 2002, p. 483–86. which means that the vapor can be condensation, condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol. An aerosol is a suspension of tiny particles of liquid, solid, or both within a gas. For example, water has a critical temperature of , which is the highest temperature at which liquid water can exist. In the Earth's atmosphere, atmosphere at ordinary temperatures gaseous water (known as water vapor) will condense into a liquid if its partial pressure is increased sufficiently. A vapor may co-exist with a liquid (or a solid). When this is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brethren Of Purity
The Brethren of Purity ( ar, إخوان الصفا, Ikhwān Al-Ṣafā; also The Brethren of Sincerity) were a secret society of Muslim philosophers in Basra, Iraq, in the 9th or 10th century CE. The structure of the organization and the identities of its members have never been clear."Having been hidden within the cloak of secrecy from its very inception, the ''Rasa'il'' have provided many points of contention and have been a constant source of dispute among both Muslim and Western scholars. The identification of the authors, or possibly one author, the place and time of writing and propagation of their works, the nature of the secret brotherhood, the outer manifestation of which comprises the ''Rasa'il'' – these and many secondary questions have remained without answer." pg 25, Nasr (1964) Their esoteric teachings and philosophy are expounded in an epistolary style in the '' Encyclopedia of the Brethren of Purity'' (''Rasa'il Ikhwan al-safa), a giant compendium of 52 epist ...

Ibn Miskawayh ( fa, مُسْکُـوْيَه Muskūyah, 932–1030), full name Abū ʿAlī Aḥmad ibn Muḥammad ibn Yaʿqūb ibn Miskawayh was a Persian chancery official of the Buyid era, and philosopher and historian from Parandak, Iran. As a Neoplatonist, his influence on Islamic philosophy is primarily in the area of ethics. He was the author of the first major Islamic work on philosophical ethics entitled the ''Refinement of Character'' ( ''Tahdhīb'' ''al''-''Akhlāq''), focusing on practical ethics, conduct, and refinement of character. He separated personal ethics from the public realm, and contrasted the liberating nature of reason with the deception and temptation of nature. Miskawayh was a prominent figure in the intellectual and cultural life of his time. Life Miskawayh was born in Rey, then under Ziyarid control. Miskawayh may have been a Zoroastrian convert to Islam, but it seems more likely that it was one of his ancestors who converted. During his early career, ...
