Ancestral community

from Wikipedia, the free encyclopedia

Ancestral community denotes in genealogy (family history research) the correspondence between people in relation to common ancestors (ancestors). Full siblings have a complete, congruent ancestral community due to their identical ancestors.

In genealogy, an ancestral community between two people is used as a limitation if their last common ancestor is at least 5  generations back. Such a distant consanguinity is often only revealed after a detailed comparison of their two ancestral lists . You can grandmother, for example, by the same Ururur ... descended , as a result, their two developed side lines but separated. Especially in the earlier common lineages (“male tribe ”), the information about ancestors of the maternal side was mostly given less attention. Become subjects When compared from different generations, each caregiver has a different number of generations from the last common ancestor.

Up to the family in the 4th generation of ancestors, specific family names are used, for example cousin or 3rd degree cousin with common descent from great-great-grandparents . If the last common ancestor is further back, this is unspecifically referred to as an ancestral community .

In other contexts, ancestral community refers to the "community of ancestors", which includes all deceased or mythical ancestors of a social group , for example a clan association, or the experienced "community with the ancestors" in ancestral cults .

Ancestral community of humanity

Starting from the image of a large family tree , two branches can be traced back until they meet the point of their ramification where they branch off from each other. This is where the last common ancestor of the two branches (lines) can be found. Viewed from below, the whole trunk and the main branch belong to the ancestral community, while after the branching the (side) lines of the kinship developed separately from each other. As a result, all branches of the tree in the past share an ancestral community that, depending on the individual branch, is further back. Seen in this way, countless people today are even blood related to one another without being aware of this fact.

An example: Based on the last common ancestors in the 11th previous generation of the great , great , great , great , great , great-grandparents , each child of these parents has statistically calculated 1024 descendants to date  (2 to the power of 10), provided that the line has not "expired" and there was no ancestral loss (see also Mathematical consideration of the ancestral generations ). The presently living descendants of these sidelines are 10th cousins ​​to one another. Countless such lateral lines branched out in previous generations as well as in later generations, each with a corresponding number of offspring. Each person within one of these lines is (distantly) related to all other people from all other lines and has an ancestral community with them that goes back to prehistoric times.

The archaeological genetics ( archaeogenetics ) has calculated in models that all people alive today are blood related, because all of only one ancestor and one descended ancestor who or approximately 100,000 to 200,000 years ago in Africa , however, (lived both lived not at the same Time, see Eve of the mitochondria and Adam of the Y chromosome ). The entire world population is therefore genetically closely linked through their common ancestral community . According to the biological theory of descent , all human beings are related by blood to all living things on earth.

Genealogy

Genealogists try to uncover even very distant relationships between people by exchanging and comparing the data they have collected. In order to determine backward branching points from different lines, information about all ancestors of the paternal and maternal side is required as completely as possible . These can be supplemented, for example, by searching the ancestral index of the German people and the ancestral list collection without having to look at the underlying sources (see research methods of genealogy ).

By comparing your own ancestral list with that of famous personalities, you can often find surprising common ancestors, sometimes even your own direct descent from the known person. Cross relationships with the poet and thinker Johann Wolfgang von Goethe (1749–1832), or even 1000 years earlier with the Frankish King Charlemagne, are popular in the German cultural area .
