Telegony (theory)
Telegony was a theory of heredity holding that offspring can inherit the characteristics of a previous mate of the female parent; thus the child of a woman might partake of traits of a previous sexual partner. Experiments in the late 19th century on several species failed to provide evidence that offspring would inherit any character from their mother's previous mates. It was superseded by the rediscovery of Mendelian inheritance and the Boveri–Sutton chromosome theory. No evidence exists of any true telegenetic mechanism of inheritance. Etymology and description Telegony is that idea that the a female will be permanently affected the time she is first impregnated, since the fetus will pass back characteristics to her that will affect all future offspring, no matter their progeny. The term was coined by August Weismann from the Greek words τῆλε (tèle) meaning 'far' and γονος (gonos) meaning 'offspring'. Early perceptions The idea of telegony goes back ...

Heredity
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics. Overview In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents. Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype. The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment. As a result, many aspects of an organism's phenotype are not inherited. For example, suntanned skin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob
Jacob (; ; ar, يَعْقُوب, Yaʿqūb; gr, Ἰακώβ, Iakṓb), later given the name Israel, is regarded as a patriarch of the Israelites and is an important figure in Abrahamic religions, such as Judaism, Christianity, and Islam. Jacob first appears in the Book of Genesis, where he is described as the son of Isaac and Rebecca, and the grandson of Abraham, Sarah, and Bethuel. According to the biblical account, he was the second-born of Isaac's children, the elder being Jacob's fraternal twin brother, Esau. Jacob is said to have bought Esau's birthright and, with his mother's help, deceived his aging father to bless him instead of Esau. Later in the narrative, following a severe drought in his homeland of Canaan, Jacob and his descendants, with the help of his son Joseph (who had become a confidant of the pharaoh), moved to Egypt where Jacob died at the age of 147. He is supposed to have been buried in the Cave of Machpelah. Jacob had twelve sons through four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Everard Home
Sir Everard Home, 1st Baronet, FRS (6 May 1756, in Kingston upon Hull – 31 August 1832, in London) was a British surgeon. Home was born in Kingston-upon-Hull and educated at Westminster School. He gained a scholarship to Trinity College, Cambridge, but decided instead to become a pupil of his brother-in-law, John Hunter, at St George's Hospital. Hunter had married his sister, the poet and socialite Anne Home, in July 1771. He assisted Hunter in many of his anatomical investigations, and in the autumn of 1776 he partly described Hunter's collection. There is also considerable evidence that Home plagiarized Hunter's work, sometimes directly, sometimes indirectly; he also systematically destroyed his brother-in-law's papers in order to hide evidence of this plagiarism. It seems likely that the fire (in Home's apartments at Chelsea Hospital) which destroyed the Hunterian manuscripts in Home's possession also destroyed a precious collection of 26 microscopes originally made by ...

Lord Morton's Mare
Lord Morton’s mare was an equid hybrid and once an often-noticed example in the history of evolutionary theory. In 1820, George Douglas, 16th Earl of Morton, F.R.S., reported to the President of the Royal Society that, being desirous of domesticating the quagga (a now extinct subspecies of the plains zebra), he had bred an Arabian chestnut mare with a quagga stallion A stallion is a male horse that has not been gelded (castrated). Stallions follow the conformation and phenotype of their breed, but within that standard, the presence of hormones such as testosterone may give stallions a thicker, "cresty" nec ... and that, subsequently, the same mare was bred with a black stallion and Lord Morton found that the offspring had strange stripes in the legs like the quagga. The Royal Society published Lord Morton's letter in its ''Philosophical Transactions'', 1821. In the same issue "Particulars of a Fact, nearly similar to that related by Lord Morton, communicated to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantagenet
The House of Plantagenet () was a royal house which originated from the lands of Anjou in France. The family held the English throne from 1154 (with the accession of Henry II at the end of the Anarchy) to 1485, when Richard III died in battle. Under the Plantagenets, England was transformed. The Plantagenet kings were often forced to negotiate compromises such as Magna Carta, which had served to constrain their royal power in return for financial and military support. The king was no longer considered an absolute monarch in the nation—holding the prerogatives of judgement, feudal tribute, and warfare—but now also had defined duties to the kingdom, underpinned by a sophisticated justice system. A distinct national identity was shaped by their conflict with the French, Scots, Welsh and Irish, as well as by the establishment of the English language as the primary language. In the 15th century, the Plantagenets were defeated in the Hundred Years' War and beset with social, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joan Of Kent
Joan, Countess of Kent (29 September 1326/1327 – 7 August 1385), known as The Fair Maid of Kent, was the mother of King Richard II of England, her son by her third husband, Edward the Black Prince, son and heir apparent of King Edward III. Although the French chronicler Jean Froissart called her "the most beautiful woman in all the realm of England, and the most loving", the appellation "Fair Maid of Kent" does not appear to be contemporary.Tait Joan inherited the titles 4th Countess of Kent and 5th Baroness Wake of Liddell after the death of her brother John, 3rd Earl of Kent, in 1352. Joan was made a Lady of the Garter in 1378. Early life Joan was born on 29 September of either 1326 or 1327 and was the daughter of Edmund of Woodstock, 1st Earl of Kent (1301-1330), by his wife, Margaret Wake, 3rd Baroness Wake of Liddell. Edmund was the sixth son of King Edward I of England by his second wife, Margaret of France, daughter of King Philip III of France. Edmund was always ...

Edward III Of England
Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England and Lord of Ireland from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. EdwardIII transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign was one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and the throne passed to his grandson, Richard II. Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover Roger Mortimer. At age seventeen he led a successful coup d'état against Mortimer, the ''de facto'' ruler of the coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward, The Black Prince
Edward of Woodstock, known to history as the Black Prince (15 June 1330 – 8 June 1376), was the eldest son of King Edward III of England, and the heir apparent to the English throne. He died before his father and so his son, Richard II, succeeded to the throne instead. Edward nevertheless earned distinction as one of the most successful English commanders during the Hundred Years' War, being regarded by his English contemporaries as a model of chivalry and one of the greatest knights of his age. Edward was made Duke of Cornwall, the first English dukedom, in 1337. He was guardian of the kingdom in his father's absence in 1338, 1340, and 1342. He was created Prince of Wales in 1343 and knighted by his father at La Hougue in 1346. In 1346, Prince Edward commanded the vanguard at the Battle of Crécy, his father intentionally leaving him to win the battle. He took part in Edward III's 1349 Calais expedition. In 1355, he was appointed the king's lieutenant in Gascony, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adultery
Adultery (from Latin ''adulterium'') is extramarital sex that is considered objectionable on social, religious, moral, or legal grounds. Although the sexual activities that constitute adultery vary, as well as the social, religious, and legal consequences, the concept exists in many cultures and is similar in Christianity, Judaism and Islam. Adultery is viewed by many jurisdictions as offensive to public morals, undermining the marriage relationship. Historically, many cultures considered adultery a very serious crime, some subject to severe punishment, usually for the woman and sometimes for the man, with penalties including capital punishment, mutilation, or torture. Such punishments have gradually fallen into disfavor, especially in Western countries from the 19th century. In countries where adultery is still a criminal offense, punishments range from fines to caning and even capital punishment. Since the 20th century, criminal laws against adultery have become controversi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nag Hammadi
Nag Hammadi ( ; ar, نجع حمادى ) is a city in Upper Egypt. It is located on the west bank of the Nile in the Qena Governorate, about north-west of Luxor. It had a population of close to 43,000 . History The town of Nag Hammadi is named after its founder, Mahmoud Pasha Hammadi, a member of the Hammadi family in Sohag, Egypt. Mahmoud Pasha Hammadi was a major landholder in Sohag, and known for his strong opposition to the British rule in Egypt beginning in 1882. Nag Hammadi is about west of ancient Chenoboskion ( grc, Χηνοβόσκιον) The "Nag Hammadi Library", an important collection of 2nd-century Gnostic texts, was found at Jabal al-Ṭārif near Nag Hammadi in 1945.. "The Nag Hammadi Library consists of twelve books, plus eight leaves removed from a thirteenth book in late antiquity and tucked inside the front cover of the sixth. These eight leaves comprise a complete text, an independent treatise taken out of a book of collected essays". (p. 10). The ...

Gospel Of Philip
The Gospel of Philip is a non-canonical Gnostic Gospel dated to around the 3rd century but lost in medieval times until rediscovered by accident, buried with other texts near Nag Hammadi in Egypt, in 1945. The text is not closely related to the canonical gospels and is not accepted as canonical by the Christian church. Although it may have some relationship to the beliefs expressed in the Gospel of Thomas, scholars are divided as to whether it should be read as a single discourse or as a collection of otherwise unrelated Valentinian sayings. Sacraments, in particular the sacrament of marriage, are a major theme. As in other texts often associated with what has been referred to as "Gnosticism," such as the Gospel of Thomas and Gospel of Mary, the Gospel of Philip defends a tradition that gives Mary Magdalene a special relationship and insight into Jesus' teaching. Date of composition The gospel's title appears at the end of the Coptic manuscript in a colophon; the only connecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
