In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA) or concestor, of a set of organisms is the most recent individual from which all the organisms of the set are descended. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms.
The MRCA of a set of individuals can sometimes be determined by referring to an established pe…Wikipedia · Text under CC-BY-SA license - https://en.wikipedia.org/wiki/Talk:Last_universal_common_ancestor
