Genealogical in the context of "Louis III, Duke of Württemberg"

Ernst Heinrich Philipp August Haeckel (/ˈhɛkəl/; German: [ɛʁnst ˈhɛkl̩]; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ecology, phylum, phylogeny, ontogeny, and Protista. Haeckel promoted and popularised Charles Darwin's work in Germany and developed the disproven but influential recapitulation theory ("ontogeny recapitulates phylogeny"), wrongly claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny, using incorrectly drawn images of human embryonic development. Whether they were intentionally falsified, or drawn poorly by accident is a matter of debate.

The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his Kunstformen der Natur ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic movement. As a philosopher, Ernst Haeckel wrote Die Welträthsel (1895–1899; in English: The Riddles of the Universe, 1900), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching to support teaching evolution.

A family Bible is a Bible handed down through a Christian family, with each successive generation recording information about the family's history inside of it. Typically, this information consists of births, deaths, baptisms, confirmations and marriages; family Bibles contain a "family record" or "family registry" section to record this information. People sometimes may place other items, such as holy cards, certificates, letters, newspaper cuttings and photographs, inside a family Bible. In the United Kingdom, they are found today and were especially common in the Victorian period, and are also found in the United States, Canada, Australia and New Zealand. Family Bibles are often placed on a family's home altar, being regularly used for family prayer. They are often used as sources for genealogical research.

An officer of arms is a person appointed by a sovereign or state with authority to perform one or more of the following functions:

• to control and initiate armorial matters;
• to arrange and participate in ceremonies of state;
• to conserve and interpret heraldic and genealogical records.

Ambilineality is a form of kinship affiliation of cognatic descent that relies on self-defined affiliation within a given social system, meaning individuals have the choice to be affiliated with their mother's or father's group. Common features of societies that practice ambilineality are a shared set of land, communal responsibilities, and collective ownership of some segments of wealth and debt in their societies. This system of descent is distinct from more common genealogical structures in that rather than determining affiliation and descent using the standard determinants of biological and genealogical relation, it instead relies heavily on voluntary affiliation with one's group, oftentimes being determined by factors including residence.

Societies practicing ambilineal descent are especially common in Southeast Asia and the Pacific Islands. Polynesian cultures and Micronesian cultures are often ambilineal, including, for example, Samoans, Māori, Hawaiians and people of the Gilbert Islands. The indigenous peoples of Northwestern North America are also followers of ambilineality; and it is also found among the Southern Yoruba people residing in West Africa.
