Matrilineage
Matrilineality is the tracing of kinship through the female line. It may also correlate with a social system in which each person is identified with their matriline – their mother's lineage – and which can involve the inheritance of property and/or titles. A matriline is a line of descent from a female ancestor to a descendant (of either sex) in which the individuals in all intervening generations are mothersin other words, a "mother line". In a matrilineal descent system, an individual is considered to belong to the same descent group as their mother. This ancient matrilineal descent pattern is in contrast to the currently more popular pattern of patrilineal descent from which a family name is usually derived. The ''matriline'' of historical nobility was also called their enatic or uterine ancestry, corresponding to the patrilineal or "agnatic" ancestry. Early human kinship In the late 19th century, almost all prehistorians and anthropologists believed, followin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Family
Family (from la, familia) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary locus of Attachment theory, attachment, nurturance, and socialization. Anthropologists classify most family organizations as Matrifocal family, matrifocal (a mother and her children), patrifocal (a father and his children), wikt:conjugal, conjugal (a wife, her husband, and children, also called the nuclear family), avuncular (a man, his sister, and her children), or Extended family, extended (in addition to parents and children, may include grandparents, aunts, uncles, or cousins). The field of genealogy aims to trace family lineages ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Seven Daughters Of Eve
''The Seven Daughters of Eve'' is a 2001 semi-fictional book by Bryan Sykes that presents the science of human origin in Africa and their dispersion to a general audience. Sykes explains the principles of genetics and human evolution, the particularities of mitochondrial DNA, and analyses of ancient DNA to genetically link modern humans to prehistoric ancestors. Following the developments of mitochondrial genetics, Sykes traces back human migrations, discusses the "out of Africa theory" and casts serious doubt upon Thor Heyerdahl's theory of the Peruvian origin of the Polynesians, which opposed the theory of their origin in Indonesia. He also describes the use of mitochondrial DNA in identifying the remains of Emperor Nicholas II of Russia, and in assessing the genetic makeup of modern Europe. The title of the book comes from one of the principal achievements of mitochondrial genetics, which is the classification of all modern Europeans into seven groups, the '' mitochondrial ...

Matriname
A matrilineal surname or matrinameSykes, Bryan (2001). ''The Seven Daughters of Eve''. W.W. Norton. ; pp. 291–2. Professor Bryan Sykes uses "matriname", only, and states that women adding their own matriname to men's patriname (or "surname" as Sykes calls it) would really help in future genealogy work and historical-record searches. This effectively suggests the ''double surname'' presented in this article. Professor Sykes also states on p. 292 that a woman's matriname will be handed down with her mtDNA, the main topic of his book. is a family name inherited from one's mother, and maternal grandmother, and so on whose line of descent is called a mother-line, mitochondrial line, or matriline. A matriname passed on to subsequent issue is unchanged, as compared to a matronymic, which is derived from the first name of each new mother. The term "matriname" was introduced by Prof. Bryan Sykes in his book ''The Seven Daughters of Eve'', stating that "We would then all have three names ...

Surname
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community. Practices vary by culture. The family name may be placed at either the start of a person's full name, as the forename, or at the end; the number of surnames given to an individual also varies. As the surname indicates genetic inheritance, all members of a family unit may have identical surnames or there may be variations; for example, a woman might marry and have a child, but later remarry and have another child by a different father, and as such both children could have different surnames. It is common to see two or more words in a surname, such as in compound surnames. Compound surnames can be composed of separate names, such as in traditional Spanish culture, they can be hyphenated together, or may contain prefixes. Using names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philopatry
Philopatry is the tendency of an organism to stay in or habitually return to a particular area. The causes of philopatry are numerous, but natal philopatry, where animals return to their birthplace to breed, may be the most common. The term derives from the Greek roots ''philo'', "liking, loving" and ''patra'', "fatherland", although in recent years the term has been applied to more than just the animal's birthplace. Recent usage refers to animals returning to the same area to breed despite not being born there, and migratory species that demonstrate site fidelity: reusing stopovers, staging points, and wintering grounds. Some of the known reasons for organisms to be philopatric would be for mating (reproduction), survival, migration, parental care, resources, etc.. In most species of animals, individuals will benefit from living in groups, because depending on the species, individuals are more vulnerable to predation and more likely to have difficulty finding resources and food. ...

Patrilocal Residence
In social anthropology, patrilocal residence or patrilocality, also known as virilocal residence or virilocality, are terms referring to the social system in which a married couple resides with or near the husband's parents. The concept of location may extend to a larger area such as a village, town or clan territory. The practice has been found in around 70 percent of the world's modern human cultures that have been described ethnographically. Archaeological evidence for patrilocality has also been found among Neanderthal remains in Spain and for ancient hominids in Africa. Description In a patrilocal society, when a man marries, his wife joins him in his father's home or compound, where they raise their children. These children will follow the same pattern. Sons will stay and daughters will move in with their husbands' families. Families living in a patrilocal residence generally assume joint ownership of domestic sources. The household is led by a senior member, who also dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matrilocal Residence
In social anthropology, matrilocal residence or matrilocality (also uxorilocal residence or uxorilocality) is the societal system in which a married couple resides with or near the wife's parents. Thus, the female offspring of a mother remain living in (or near) the mother's house, thereby forming large clan-families, typically consisting of three or four generations living in the same place. Description Frequently, visiting marriage is being practiced, meaning that husband and wife are living apart, in their separate birth families, and seeing each other in their spare time. The children of such marriages are raised by the mother's extended matrilineal clan. The father does not have to be involved in the upbringing of his own children; he does, however, in that of his sisters' children (his nieces and nephews). In direct consequence, property is inherited from generation to generation, and, overall, remains largely undivided. Matrilocal residence is found most often in ho ...

Sub-Saharan Africa
Sub-Saharan Africa is, geographically, the area and regions of the continent of Africa that lies south of the Sahara. These include West Africa, East Africa, Central Africa, and Southern Africa. Geopolitically, in addition to the List of sovereign states and dependent territories in Africa, African countries and territories that are situated fully in that specified region, the term may also include polities that only have part of their territory located in that region, per the definition of the United Nations (UN). This is considered a non-standardized geographical region with the number of countries included varying from 46 to 48 depending on the organization describing the region (e.g. UN, WHO, World Bank, etc.). The Regions of the African Union, African Union uses a different regional breakdown, recognizing all 55 member states on the continent - grouping them into 5 distinct and standard regions. The term serves as a grouping counterpart to North Africa, which is instead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeoanthropologist
Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural evidence (such as stone tools, artifacts, and settlement localities). The field draws from and combines primatology, paleontology, biological anthropology, and cultural anthropology. As technologies and methods advance, genetics plays an ever-increasing role, in particular to examine and compare DNA structure as a vital tool of research of the evolutionary kinship lines of related species and genera. Etymology The term paleoanthropology derives from Greek palaiós (παλαιός) "old, ancient", ánthrōpos (ἄνθρωπος) "man, human" and the suffix -logía (-λογία) "study of". Hom ...

Evolutionary Biologist
Evolutionary biology is the subfield of biology that studies the evolutionary processes (natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution is based on the theory that all species are related and they gradually change over time. In a population, the genetic variations affect the physical characteristics i.e. phenotypes of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed onto their offspring. Some examples of evolution in species over many generations are the Peppered Moth and Flightless birds. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The importance of studying Evolutionary biology is ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
