Patrilineality
Patrilineality, also known as the male line, the spear side or agnatic kinship, is a common kinship system in which an individual's family membership derives from and is recorded through their father's lineage. It generally involves the inheritance of property, rights, names, or titles by persons related through male kin. This is sometimes distinguished from cognate kinship, through the mother's lineage, also called the spindle side or the distaff side. A patriline ("father line") is a person's father, and additional ancestors, as traced only through males. Traditionally and historically people would identify the person's ethnicity with the father's heritage and ignore the maternal ancestry in the ethnic factor. In the Bible In the Bible, family and tribal membership appears to be transmitted through the father. For example, a person is considered to be a priest or Levite, if his father is a priest or Levite, and the members of all the Twelve Tribes are called Israelites be ...

Kinship
In anthropology, kinship is the web of social relationships that form an important part of the lives of all humans in all societies, although its exact meanings even within this discipline are often debated. Anthropologist Robin Fox says that the study of kinship is the study of what humans do with these basic facts of lifemating, gestation, parenthood, socialization, siblingship etc. Human society is unique, he argues, in that we are "working with the same raw material as exists in the animal world, but ecan conceptualize and categorize it to serve social ends." These social ends include the socialization of children and the formation of basic economic, political and religious groups. Kinship can refer both to the patterns of social relationships themselves, or it can refer to the study of the patterns of social relationships in one or more human cultures (i.e. kinship studies). Over its history, anthropology has developed a number of related concepts and terms in the study ...

Tribal Membership
The term tribe is used in many different contexts to refer to a category of human social group. The predominant worldwide usage of the term in English is in the discipline of anthropology. This definition is contested, in part due to conflicting theoretical understandings of social and kinship structures, and also reflecting the problematic application of this concept to extremely diverse human societies. The concept is often contrasted by anthropologists with other social and kinship groups, being hierarchically larger than a lineage or clan, but smaller than a chiefdom, nation or state. These terms are equally disputed. In some cases tribes have legal recognition and some degree of political autonomy from national or federal government, but this legalistic usage of the term may conflict with anthropological definitions. In the United States, Native American tribes are legally considered to have "domestic dependent nation" status within the territorial United States, with ...

Kohen
Kohen ( he, , ''kōhēn'', , "priest", pl. , ''kōhănīm'', , "priests") is the Hebrew word for " priest", used in reference to the Aaronic priesthood, also called Aaronites or Aaronides. Levitical priests or ''kohanim'' are traditionally believed and halakhically required to be of direct patrilineal descent from the biblical Aaron (also ''Aharon''), brother of Moses. During the existence of the Temple in Jerusalem, ''kohanim'' performed the daily and holiday ( Yom Tov) duties of sacrificial offerings. Today, ''kohanim'' retain a lesser though distinct status within Rabbinic and Karaite Judaism and are bound by additional restrictions according to Orthodox Judaism. In the Samaritan community, the kohanim have remained the primary religious leaders. Ethiopian Jewish religious leaders are sometimes called '' kahen'', a form of the same word, but the position is not hereditary and their duties are more like those of rabbis than kohanim in most Jewish communities. Et ...

Levite
Levites (or Levi) (, he, ''Lǝvīyyīm'') are Jewish males who claim patrilineal descent from the Tribe of Levi. The Tribe of Levi descended from Levi, the third son of Jacob and Leah. The surname ''Halevi'', which consists of the Hebrew definite article "" ''Ha-'' ("the") plus ''Levi'' (Levite) is not conclusive regarding being a Levite; a titular use of HaLevi indicates being a Levite. The daughter of a Levite is a " ''Bat Levi''" (''Bat'' being Hebrew for "daughter"). The Tribe of Levi served particular religious duties for the Israelites and had political (administering cities of refuge) and educational responsibilities as well. In return, the landed tribes were expected to support the Levites with a tithe (), particularly the tithe known as the First tithe, ''ma'aser rishon''. The Kohanim, a subset of the Levites, were the priests, who performed the work of holiness in the Temple. The Levites, referring to those who were not Kohanim, were specifically assigned to * ...

Y-chromosomal Adam
In human genetics, the Y-chromosomal most recent common ancestor (Y-MRCA, informally known as Y-chromosomal Adam) is the patrilineal most recent common ancestor (MRCA) from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors. The term Y-MRCA reflects the fact that the Y chromosomes of all currently living human males are directly derived from the Y chromosome of this remote ancestor. The analogous concept of the matrilineal most recent common ancestor is known as " Mitochondrial Eve" (mt-MRCA, named for the matrilineal transmission of mtDNA), the most recent woman from whom all living humans are descended matrilineally. As with "Mitochondrial Eve", the title of "Y-chromosomal Adam" is not permanently fixed to a single individual, but can advance over the course of human history as paternal lineages become extinct. Estimates of the time when Y-MRCA lived have also shift ...

Most Recent Common Ancestor
In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA) or concestor, of a set of organisms is the most recent individual from which all the organisms of the set are descended. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The MRCA of a set of individuals can sometimes be determined by referring to an established pedigree. However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such ''time to most recent common ancestor'' (''TMRCA'') estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non-genetic, mathematical model or computer simulation. In organisms using sexual reproduction, the ''matrilineal MRCA'' and ''patrilineal MRCA'' are the MRCAs of a given population ...

Salic Law
The Salic law ( or ; la, Lex salica), also called the was the ancient Frankish civil law code compiled around AD 500 by the first Frankish King, Clovis. The written text is in Latin and contains some of the earliest known instances of Old Dutch. It remained the basis of Frankish law throughout the early Medieval period, and influenced future European legal systems. The best-known tenet of the old law is the principle of exclusion of women from inheritance of thrones, fiefs, and other property. The Salic laws were arbitrated by a committee appointed and empowered by the King of the Franks. Dozens of manuscripts dating from the sixth to eighth centuries and three emendations as late as the ninth century have survived. Salic law provided written codification of both civil law, such as the statutes governing inheritance, and criminal law, such as the punishment for murder. Although it was originally intended as the law of the Franks, it has had a formative influence on the trad ...

Dynasty
A dynasty is a sequence of rulers from the same family,''Oxford English Dictionary'', "dynasty, ''n''." Oxford University Press (Oxford), 1897. usually in the context of a monarchical system, but sometimes also appearing in republics. A dynasty may also be referred to as a "house", "family" or "clan", among others. Historians periodize the histories of many states and civilizations, such as Ancient Iran (3200 - 539 BC), Ancient Egypt (3100 – 30 BC) and Ancient and Imperial China (2070 BC – AD 1912), using a framework of successive dynasties. As such, the term "dynasty" may be used to delimit the era during which a family reigned. Before the 18th century, most dynasties throughout the world have traditionally been reckoned patrilineally, such as those that follow the Frankish Salic law. In polities where it was permitted, succession through a daughter usually established a new dynasty in her husband's family name. This has changed in all of Europe's remainin ...

Molecular Clock
The molecular clock is a figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged. The biomolecular data used for such calculations are usually nucleotide sequences for DNA, RNA, or amino acid sequences for proteins. The benchmarks for determining the mutation rate are often fossil or archaeological dates. The molecular clock was first tested in 1962 on the hemoglobin protein variants of various animals, and is commonly used in molecular evolution to estimate times of speciation or radiation. It is sometimes called a gene clock or an evolutionary clock. Early discovery and genetic equidistance The notion of the existence of a so-called "molecular clock" was first attributed to Émile Zuckerkandl and Linus Pauling who, in 1962, noticed that the number of amino acid differences in hemoglobin between different lineages changes roughly linearly with time, as estimated from fossil evi ...

Y Chromosome
The Y chromosome is one of two sex chromosomes (allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction. In mammals, the Y chromosome contains the gene SRY, which triggers male development. The DNA in the human Y chromosome is composed of about 59 million base pairs, making it similar in size to chromosome 19. The Y chromosome is passed only from father to son. With a 30% difference between humans and chimpanzees, the Y chromosome is one of the fastest-evolving parts of the human genome. The human Y chromosome carries an estimated 100–200 genes, with between 45 and 73 of these being protein-coding gene, protein-coding. All single-copy Y-linked genes are hemizygous (present on only one chromosome) except in cases of aneuploidy such as XYY syndro ...

95% Confidence Interval
In frequentist statistics, a confidence interval (CI) is a range of estimates for an unknown parameter. A confidence interval is computed at a designated ''confidence level''; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used. The confidence level represents the long-run proportion of corresponding CIs that contain the true value of the parameter. For example, out of all intervals computed at the 95% level, 95% of them should contain the parameter's true value. Factors affecting the width of the CI include the sample size, the variability in the sample, and the confidence level. All else being the same, a larger sample produces a narrower confidence interval, greater variability in the sample produces a wider confidence interval, and a higher confidence level produces a wider confidence interval. Definition Let be a random sample from a probability distribution with statistical parameter , which is a quantity to be estimated ...

Agnatic Seniority
Agnatic seniority is a patrilineal principle of inheritance where the order of succession to the throne prefers the monarch's younger brother over the monarch's own sons. A monarch's children (the next generation) succeed only after the males of the elder generation have all been exhausted. Agnatic seniority essentially excludes females of the dynasty and their descendants from the succession. Contrast agnatic primogeniture, where the king's sons stand higher in succession than his brothers. Description In hereditary monarchies, particularly in more ancient times, seniority was a much-used principle of order of succession. The Ottoman Empire evolved from an elective succession (following the principle of agnatic seniority) to a succession inherited by the law of agnatic seniority. In succession based on rotation (close to seniority), all (male) members of the dynasty were entitled to the monarchy, in principle. However, this tends to lead to situations where there is no cl ...
