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.
