does_have_any_common_ancestor
- does_have_any_common_ancestor(first: Union[HereditaryStratigraphicColumn, HereditaryStratigraphicSpecimen], second: Union[HereditaryStratigraphicColumn, HereditaryStratigraphicSpecimen], confidence_level: float = 0.95) bool | None
Determine if common ancestry is evidenced with second.
If insufficient common ranks between first and second are available to resolve any common ancestor, returns None.
Note that stratum rention policies are strictly required to permanently retain the most ancient stratum.
Parameters
- confidence_levelfloat, optional
The probability that we will correctly conclude no common ancestor is shared with second if, indeed, no common ancestor is actually shared. Default 0.95.
