common ancestor wikipedia - EAS
- In biology and genealogy, the most recent common ancestor ( MRCA), 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 last universal common ancestor (LUCA) is the most recent population from which all organisms now living on Earth share common descent—the most recent common ancestor of all current life on Earth. This includes all cellular organisms; the origins of viruses are unclear but they share the same genetic code. LUCA probably harboured a variety of viruses. The LUCA is not the firs…

https://en.wikipedia.org/wiki/Lowest_common_ancestor- In graph theory and computer science, the lowest common ancestor of two nodes v and w in a tree or directed acyclic graph T is the lowest node that has both v and w as descendants, where we define each node to be a descendant of itself. The LCA of v and w in T is the shared ancestor of v and w that is located farthest from the root. Computation of ...

- Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. All living beings are in fact descendants of a unique ancestor commonly referred to as the last universal common ancestor of all life on Earth, according to modern evolutionary biology. Common descent is an effect of...
