Editing Most recent common ancestor (section)

{{Main|Identical ancestors point}}
The MRCA is the most recent ''common'' ancestor shared by all individuals in the population under consideration. This MRCA may well have contemporaries who are also ancestral to some but not all of the extant population. The ''[[identical ancestors point]]'' is a point in the past more remote than the MRCA at which time there are no longer organisms which are ancestral to some but not all of the modern population. Due to pedigree collapse, modern individuals may still exhibit clustering, due to vastly different contributions from each of ancestral population.<ref name="Rohde_2004">{{cite journal |last1=Rohde |first1=Douglas L.
