| β | Because all humans are descended from a {{w|Mitochondrial Eve|common ancestor}}, every human is, at some point, related to every other human, albeit distantly.

Similarly, all life forms on Earth are presumed (with good reasons) to be descended from a single {{w|Most recent common ancestor|even more distant relative}} whose ultimate lineage {{w|Last universal common ancestor|became more relevent}} than any from its own 'cousins' at the time, and thus ''all'' life forms are distantly related. This makes every interaction with another life-form, technically, a family reunion, if not in the traditional sense. |
The general English definition of a {{w|cousin}}, which is a person sharing an ancestor who is not a direct parent of either party, can be qualified by two numbers. There is the ''n''th-ness of the relationship (the fewest generations you need to go beyond one's parentage, "a first cousin" implies that a grandparent is the key link) - for example, [[Cueball|this Cueball's]] relation to [[White Hat]] is via a great-grandparent, whilst that with [[Hairbun]] is through a great-great-great-great-great-great-great-great-grandparent. A "removed" number is any difference in this number between the two individuals, such that a child of a direct cousin invokes a "once removed" relationship between the two (without individually qualifying who is the 'senior' generation, from whom the 'nth' count is determined). You would normally only qualify "first cousin" if this fact is considered important, and "zero times removed" would also be considered implicit. | The general English definition of a {{w|cousin}}, which is a person sharing an ancestor who is not a direct parent of either party, can be qualified by two numbers.
