Describe the distinct differences between lineages, clans, moieties, and phratries are all types of decent groups.

Lineage is a descent group that can demonstrate their common descent from a known apical ancestor. depending on whether they through mother respectively
Clan is a descent group that claims common descent from an apical ancestor (but often cannot demonstrate it, or "stipulated descent"). Often, the details of parentage are not important element of the clan tradition. Non-human apical ancestors are called totems. Example: of clan are found in Chechen, Chinese, Irish, Polish, Scottish, Tlingit, and Somali societies.
Moieties are a descent group that coexists with only one other descent group within a society. (A society into two halves, usually exogamous).
Phratries is a descent group composed of two or more clans each of whose apical ancestors are descended from a further common ancestor. (people cannot marry someone belonging to their culture.

In your own words, what are the differences?

For instance, lineage groups know who the common ancestor is. Clans usually do not know who s/he is.

To understand the distinct differences between lineages, clans, moieties, and phratries as types of descent groups, let's break down each term individually:

1. Lineage: A lineage is a descent group that can demonstrate their common descent from a known apical ancestor. Lineages can be traced through the paternal or maternal line, depending on whether they are patrilineal (through the father) or matrilineal (through the mother). The key aspect of a lineage is the ability to establish a direct genealogical link to a specific apical ancestor.

2. Clan: A clan is a descent group that claims common descent from an apical ancestor, but often cannot demonstrate it. This means that clans rely on a tradition of common descent rather than verifiable genealogical records. The specific details of parentage may not be crucial to the clan's identity. In some cases, clans might attribute their origins to non-human apical ancestors known as totems. Clans can be found in various societies, such as Chechen, Chinese, Irish, Polish, Scottish, Tlingit, and Somali societies.

3. Moieties: Moieties are descent groups that exist alongside only one other descent group within a society. This means that a society is divided into two halves, with each moiety serving as a distinct descent group. One key characteristic of moieties is that they are often exogamous, meaning individuals are required to marry someone from the other moiety. Moieties are commonly found in societies that have a dualistic social organization.

4. Phratries: Phratries are descent groups composed of two or more clans, each with their apical ancestors descended from a further common ancestor. Phratries are typically larger groupings that encompass multiple clans and serve as a higher-level social organization. They often have specific rules regarding marriage, with individuals prohibited from marrying someone within their own phratry. Phratries are designed to promote social and marital alliances between different clans.

In summary, lineages are descent groups tracing direct genealogical links to an apical ancestor, clans are descent groups based on tradition rather than verifiable descent, moieties are dualistic descent groups within a society, and phratries are higher-level descent groups comprising multiple clans sharing a common ancestor. Understanding the distinctions between these types of descent groups helps to comprehend the various ways societies organize kinship and descent.
