Prehistory Of Corsica
The prehistory of Corsica is analogous to the prehistories of the other islands in the Mediterranean Sea, such as Sicily, Sardinia, Malta and Cyprus, which could only be accessed by boat and featured cultures that were to some degree insular; that is, modified from the traditional Paleolithic, Mesolithic, Neolithic and Chalcolithic of European prehistoric cultures. The islands of the Aegean Sea and Crete early developed Bronze Age civilizations and are accordingly usually treated under those categories. Stone Age Crete however shares some of the features of the prehistoric Mediterranean islands. The possible presence of Upper Paleolithic people on Corsica during the last glacial period is a topic of interest to professional and amateur prehistorians alike. Currently only one possible site of this period is known. For most of the Paleolithic, Corsica, Sardinia, and all the islands between them were physically continuous with the Italian peninsula, although they have been islands ...

Filitosa Oppidum 1
Filitosa is a megalithic site in southern Corsica, France. The period of occupation spans from the end of the Neolithic era and the beginning of the Bronze Age, until around the Roman times in Corsica. Location The site lies on road D57, a few hundred metres from the hamlet of Filitosa, west of Sollacaro, in the canton of Petreto-Bicchisano, arrondissement of Sartène, north of Propriano in the Corse-du-Sud '' département''. It is located on a hill, overlooking the Taravo valley. Site history and features The site was discovered in 1946 by the owner of the land, Charles-Antoine Cesari, and brought to the attention of archeologists by the British writer, Dorothy Carrington (see her masterpiece, ''Granite Island: Portrait of Corsica'',). Systematic excavations started in 1954 by Roger Grosjean. Finds of arrow heads and pottery date earliest inhabitation to 3300 BC. Around 1500 BC, 2-3 metre menhirs were erected. They have been carved with representations of huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allele
An allele (, ; ; modern formation from Greek ἄλλος ''állos'', "other") is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution. ::"The chromosomal or genomic location of a gene or any other genetic element is called a locus (plural: loci) and alternative DNA sequences at a locus are called alleles." The simplest alleles are single nucleotide polymorphisms (SNP). but they can also be insertions and deletions of up to several thousand base pairs. Popular definitions of 'allele' typically refer only to different alleles within genes. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants). In population genetics, nearly every living human's phenotype for the ABO gene is some combination of just these six alleles. Most alleles observed result in little or no change in the function of the gene product it codes for. However, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Distance
Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. Populations with many similar alleles have small genetic distances. This indicates that they are closely related and have a recent common ancestor. Genetic distance is useful for reconstructing the history of populations, such as the multiple human expansions out of Africa. It is also used for understanding the origin of biodiversity. For example, the genetic distances between different breeds of domesticated animals are often investigated in order to determine which breeds should be protected to maintain genetic diversity. Biological foundation In the genome of an organism, each gene is located at a specific place called the locus for that gene. Allelic variations at these loci cause phenotypic variation within species (e.g. hair colour, eye colour). However, most alleles do not hav ...

Autosome
An autosome is any chromosome that is not a sex chromosome. The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosome, allosomal (sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA. For example, humans have a diploid human genome, genome that usually contains 22 pairs of autosomes and one allosome pair (46 chromosomes total). The autosome pairs are labeled with numbers (1–22 in humans) roughly in order of their sizes in base pairs, while allosomes are labelled with their letters. By contrast, the allosome pair consists of two X chromosomes in females or one X and one Y chromosome in males. Unusual combinations of XYY syndrome, XYY, Klinefelter syndrome, XXY, Triple X syndrome, XXX, XXXX syndrome, XXXX, XXXXX syndrome, XXXXX or XXYY syndrome, XXYY, among Aneuploidy, other Salome combinations, are known to occur and usually cause developmental abnormalities. Autosomes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuscany
Tuscany ( ; it, Toscana ) is a Regions of Italy, region in central Italy with an area of about and a population of about 3.8 million inhabitants. The regional capital is Florence (''Firenze''). Tuscany is known for its landscapes, history, artistic legacy, and its influence on high culture. It is regarded as the birthplace of the Italian Renaissance and of the foundations of the Italian language. The prestige established by the Tuscan dialect's use in literature by Dante Alighieri, Petrarch, Giovanni Boccaccio, Niccolò Machiavelli and Francesco Guicciardini led to its subsequent elaboration as the language of culture throughout Italy. It has been home to many figures influential in the history of art and science, and contains well-known museums such as the Uffizi and the Palazzo Pitti. Tuscany is also known for its wines, including Chianti, Vino Nobile di Montepulciano, Morellino di Scansano, Brunello di Montalcino and white Vernaccia di San Gimignano. Having a strong linguisti ...

Core Sample
A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample different media under different conditions. More continue to be invented on a regular basis. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired. Core samples can be taken to test the properties of manmade materials, such as concrete, ceramics, some metals and alloys, especially the softer ones. Core samples can also be taken of living things, including human beings, especially of a person's bones for microscopic examination to help diagnose diseases. Methods The compo ...

Flandrian Transgression
The Flandrian interglacial or stage is the name given by geologists and archaeologists in the British Isles to the first, and so far only, stage of the Holocene epoch (the present geological period), covering the period from around 12,000 years ago, at the end of the last glacial period to the present day. As such, it is in practice identical in span to the Holocene. The Flandrian began as the relatively short-lived Younger Dryas climate downturn came to an end. This formed the last gasp of the Devensian glaciation, the final stage of the Pleistocene epoch. The Flandrian is traditionally seen as the latest warm interglacial in a series that has been occurring throughout the Quaternary geological period. The first part of the Flandrian, known as the Younger Atlantic, was a period of fairly rapid sea level rise, known as the Flandrian transgression. It is associated with the melting of the Fenno-Scandian, Scottish, Laurentide and Cordilleran glaciers. Fjords were forme ...

History Of Corsica
History (derived ) is the systematic study and the documentation of the human activity. The time period of event before the invention of writing systems is considered prehistory. "History" is an umbrella term comprising past events as well as the memory, discovery, collection, organization, presentation, and interpretation of these events. Historians seek knowledge of the past using historical sources such as written documents, oral accounts, art and material artifacts, and ecological markers. History is not complete and still has debatable mysteries. History is also an academic discipline which uses narrative to describe, examine, question, and analyze past events, and investigate their patterns of cause and effect. Historians often debate which narrative best explains an event, as well as the significance of different causes and effects. Historians also debate the nature of history as an end in itself, as well as its usefulness to give perspective on the problems of the p ...

Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aléria
Aléria (; Ancient Greek: /, ; Latin and Italian: ; co, U Cateraghju) is a commune in the Haute-Corse department of France on the island of Corsica, former bishopric and present Latin Catholic titular see. It includes the easternmost point in Metropolitan France.
