Archaic humans

A number of varieties of Homo are grouped into the broad category of archaic humans in the period contemporary and predating the emergence of the earliest anatomically modern humans (Homo sapiens) over 315 kya.

Consanguinity

Consanguinity ("blood relation", from the Latin consanguinitas) is the property of being from the same kinship as another person.

Divine providence

In theology, divine providence, or just providence, is God's intervention in the universe.

DNA

Deoxyribonucleic acid (DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.

Ethnic group

An ethnic group, or an ethnicity, is a category of people who identify with each other based on similarities such as common ancestry, language, history, society, culture or nation.

Evolution

Evolution is change in the heritable characteristics of biological populations over successive generations.

Family

Every person has his/her own family.mother reproduces with husband for children.In the context of human society, a family (from familia) is a group of people related either by consanguinity (by recognized birth), affinity (by marriage or other relationship), or co-residence (as implied by the etymology of the English word "family" from Latin familia 'family servants, domestics collectively, the servants in a household,' thus also 'members of a household, the estate, property; the household, including relatives and servants,' abstract noun formed from famulus 'servant, slave ') or some combination of these.

Genealogy

Genealogy (from γενεαλογία from γενεά, "generation" and λόγος, "knowledge"), also known as family history, is the study of families and the tracing of their lineages and history.

Genetic genealogy

Genetic genealogy is the use of DNA testing in combination with traditional genealogical methods to infer relationships between individuals and find ancestors.

Genetics

Genetics is the study of genes, genetic variation, and heredity in living organisms.

Grandparent

Grandparents are the parents of a person's father or mother – paternal or maternal.

Horizontal gene transfer

Horizontal gene transfer (HGT) or lateral gene transfer (LGT) is the movement of genetic material between unicellular and/or multicellular organisms other than by the ("vertical") transmission of DNA from parent to offspring.

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.

Lineage (anthropology)

A lineage is a unilineal descent group that can demonstrate their common descent from a known apical ancestor.

Lineal descendant

A lineal descendant, in legal usage, is a blood relative in the direct line of descent – the children, grandchildren, great-grandchildren, etc.

Mitochondrial DNA

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, adenosine triphosphate (ATP).

Most recent common ancestor

In biology and genealogy, the most recent common ancestor (MRCA, also last common ancestor (LCA), or concestor) of any set of organisms is the most recent individual from which all the organisms are directly descended.

Parent

A parent is a caregiver of the offspring in their own species.

Pedigree collapse

In genealogy, pedigree collapse describes how reproduction between two individuals who share an ancestor causes the number of distinct ancestors in the family tree of their offspring to be smaller than it could otherwise be.

Progenitor

In genealogy, the progenitor (rarer: primogenitor; Stammvater or Ahnherr) is the – sometimes legendary – founder of a family, line of descent, clan or tribe, noble house or people group.

Recursion

Recursion occurs when a thing is defined in terms of itself or of its type.

Veneration of the dead

The veneration of the dead, including one's ancestors, is based on love and respect for the deceased.
