Jean Baptiste Julien D'Omalius D'Halloy
Jean Baptiste Julien d'Omalius d'Halloy (17 February 1783 in Liège – 15 January 1875 in Brussels) was a Belgian geologist. He also wrote on races. Early life and education Born in Liège, he was the only son of an ancient and noble family, and his education was carefully directed. After completing his classical studies in his home town he was sent to Paris in 1801 by his parents to avail himself of the social and literary advantages of the metropolis. A lively interest, however, in geology awakened by the works of Buffon, directed his steps to the museums and the Jardin des Plantes. He visited Paris again in 1803 and 1805, and during these periods attended the lectures of Fourcroy, Lacépède, and Georges Cuvier. His homeward journeys were usually made the occasion of a geological expedition through northern France. As early as 1808 he communicated to the ''Journal des Mines'' a paper entitled ''Essai sur la géologie du Nord de la France''. He thus conceived the proje ...

Royal Netherlands Academy Of Arts And Sciences
The Royal Netherlands Academy of Arts and Sciences ( nl, Koninklijke Nederlandse Akademie van Wetenschappen, abbreviated: KNAW) is an organization dedicated to the advancement of science and literature in the Netherlands. The academy is housed in the Trippenhuis in Amsterdam. In addition to various advisory and administrative functions it operates a number of research institutes and awards many prizes, including the Lorentz Medal in theoretical physics, the Dr Hendrik Muller Prize for Behavioural and Social Science and the Heineken Prizes. Main functions The academy advises the Dutch government on scientific matters. While its advice often pertains to genuine scientific concerns, it also counsels the government on such topics as policy on careers for researchers or the Netherlands' contribution to major international projects. The academy offers solicited and unsolicited advice to parliament, ministries, universities and research institutes, funding agencies and internatio ...

Color Terminology For Race
Identifying human races in terms of skin color, at least as one among several physiological characteristics, has been common since antiquity. Such divisions appeared in rabbinical literature and in early modern scholarship, usually dividing humankind into four or five categories, with color-based labels: red, yellow, black, white, and sometimes brown. It was long recognized that the number of categories is arbitrary and subjective, and different ethnic groups were placed in different categories at different points in time. François Bernier (1684) doubted the validity of using skin color as a racial characteristic, and Charles Darwin (1871) emphasized the gradual differences between categories. Today there is broad agreement among scientists that typological conceptions of race have no scientific basis. History Antiquity to 1600s Categorization of racial groups by reference to skin color is common in classical antiquity. For example, it is found in e.g. ''Physiognomica'', a ...

Catholic
The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with 1.3 billion baptized Catholics worldwide . It is among the world's oldest and largest international institutions, and has played a prominent role in the history and development of Western civilization.O'Collins, p. v (preface). The church consists of 24 ''sui iuris'' churches, including the Latin Church and 23 Eastern Catholic Churches, which comprise almost 3,500 dioceses and eparchies located around the world. The pope, who is the bishop of Rome, is the chief pastor of the church. The bishopric of Rome, known as the Holy See, is the central governing authority of the church. The administrative body of the Holy See, the Roman Curia, has its principal offices in Vatican City, a small enclave of the Italian city of Rome, of which the pope is head of state. The core beliefs of Catholicism are found in the Nicene Creed. The Catholic Church teaches that it is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tertiary
Tertiary ( ) is a widely used but obsolete term for the geologic period from 66 million to 2.6 million years ago. The period began with the demise of the non-avian dinosaurs in the Cretaceous–Paleogene extinction event, at the start of the Cenozoic Era, and extended to the beginning of the Quaternary glaciation at the end of the Pliocene Epoch. The time span covered by the Tertiary has no exact equivalent in the current geologic time system, but it is essentially the merged Paleogene and Neogene periods, which are informally called the Early Tertiary and the Late Tertiary, respectively. The Tertiary established the Antarctic as an icy island continent. Historical use of the term The term Tertiary was first used by Giovanni Arduino during the mid-18th century. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in Northern Italy. Later a fourth period, the Quaternary, was applied.

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian lin ...

Ethnology
Ethnology (from the grc-gre, ἔθνος, meaning 'nation') is an academic field that compares and analyzes the characteristics of different peoples and the relationships between them (compare cultural, social, or sociocultural anthropology). Scientific discipline Compared to ethnography, the study of single groups through direct contact with the culture, ethnology takes the research that ethnographers have compiled and then compares and contrasts different cultures. The term ''ethnologia'' (''ethnology'') is credited to Adam Franz Kollár (1718-1783) who used and defined it in his ''Historiae ivrisqve pvblici Regni Vngariae amoenitates'' published in Vienna in 1783. as: “the science of nations and peoples, or, that study of learned men in which they inquire into the origins, languages, customs, and institutions of various nations, and finally into the fatherland and ancient seats, in order to be able better to judge the nations and peoples in their own times.” Koll� ...

Descent With Modification
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
