Mitochondrial Eve (novelette)
"Mitochondrial Eve" is a science-fiction novelette by Australian writer Greg Egan, first published in '' Interzone #92'' in February 1995. The novelette was included in the anthology ''The Best of Interzone'' in 1997 and in the collection ''Luminous'' in 1998. Plot Paul and Lena visit an exhibition in which they see current research to trace back the ancestors of modern humans who are all related to each other. A group called Children of Eve plans to trace back a common female ancestor of all Europeans, called Eve, since male lineages are lost more quickly due to polygamy. Paul and Lena discuss the involvement of quantum effects in the duplication of DNA and intend to do further research to apply it to genetic tracing. Many years later, an opposing group claims to have found a common male ancestor of all Europeans called Adam. Paul and Lena meet in London to witness this launching multiple claims about other common ancestors as well as violent eruptions fueled by racist defense ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic ( Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in ...

Interzone (magazine)
''Interzone'' is a British fantasy and science fiction magazine. Published since 1982, ''Interzone'' is the eighth-longest-running English language science fiction magazine in history, and the longest-running British science fiction (SF) magazine. Stories published in ''Interzone'' have been finalists for the Hugo Awards and have won a Nebula Award and numerous British Science Fiction Awards. History ''Interzone'' was initially produced by an unpaid collective of eight peopleJohn Clute, Alan Dorey, Malcolm Edwards, Colin Greenland, Graham James, Roz Kaveney, Simon Ounsley and David Pringle. According to Dorey, the group had been fans of the science fiction magazine '' New Worlds'' and wanted to create a "''New Worlds'' for the 1980s, something that would publish only great fiction and be a proper outlet for new writers." While the magazine started as an editorial collective, soon editor David Pringle was the driving force behind ''Interzone''. In 1984 ''Interzone'' receive ...

Periodical
A periodical literature (also called a periodical publication or simply a periodical) is a published work that appears in a new edition on a regular schedule. The most familiar example is a newspaper, but a magazine or a journal are also examples of periodicals. These publications cover a wide variety of topics, from academic, technical, trade, and general interest to leisure and entertainment. Articles within a periodical are usually organized around a single main subject or theme and include a title, date of publication, author(s), and brief summary of the article. A periodical typically contains an editorial section that comments on subjects of interest to its readers. Other common features are reviews of recently published books and films, columns that express the author's opinions about various topics, and advertisements. A periodical is a serial publication. A book is also a serial publication, but is not typically called a periodical. An encyclopedia or dictionary is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luminous (book)
''Luminous'' is a collection of short science fiction stories by Greg Egan. Contents ''Luminous'' contains the following short stories: *"Chaff" — An agent is sent to kill a geneticist who is working in a drug lord-controlled stronghold in the jungles of Colombia, and working on important brain-altering research. *"Mitochondrial Eve" — An organisation is trying to trace a common maternal ancestor for recent humanity. *"Luminous" — A pair of researchers find a defect in mathematics, where an assertion (X) leads to a contradictory assertion (not X) after a long but finite series of steps.

Polygamy
Crimes Polygamy (from Late Greek (') "state of marriage to many spouses") is the practice of marrying multiple spouses. When a man is married to more than one wife at the same time, sociologists call this polygyny. When a woman is married to more than one husband at a time, it is called polyandry. In contrast to polygamy, monogamy is marriage consisting of only two parties. Like "monogamy", the term "polygamy" is often used in a '' de facto'' sense, applied regardless of whether a state recognizes the relationship.For the extent to which states can and do recognize potentially and actual polygamous forms as valid, see Conflict of marriage laws. In sociobiology and zoology, researchers use ''polygamy'' in a broad sense to mean any form of multiple mating. Worldwide, different societies variously encourage, accept or outlaw polygamy. In societies which allow or tolerate polygamy, in the vast majority of cases the form accepted is polygyny. According to the ''Ethnog ...

Quantum Effects
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary ( macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves ( wave–particle duality); and there are li ...

Gene Duplication
Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene. Gene duplications can arise as products of several types of errors in DNA replication and repair machinery as well as through fortuitous capture by selfish genetic elements. Common sources of gene duplications include ectopic recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage. Mechanisms of duplication Ectopic recombination Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes. The products of this recombination are a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombinatio ...
