The last universal common ancestor (LUCA) is the hypothesized common ancestral cell from which the three domains of life, the Bacteria, the Archaea, and the Eukarya originated. The cell had a lipid bilayer ; it possessed the genetic code and ribosomes which translated from DNA or RNA to proteins .
Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth.

In biology and genetic genealogy, the most recent common ancestor (MRCA), also known as the last common ancestor (LCA), 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 rather than organisms.
Scots is considered to be a sister language of English because they are both descended from the common ancestor Old English (via Early Middle English). The phonological development of the two languages is divergent, with different loanwords entering each language from sources such as Norse, Latin, and French.
Google Translate is a multilingual neural machine translation service developed by Google to translate text, documents and websites from one language into another. It offers a website interface, a mobile app for Android and iOS, as well as an API that helps developers build browser extensions and software applications. [3]
The first universal common ancestor (FUCA) is a proposed non-cellular entity that was the earliest organism with a genetic code capable of biological translation of RNA molecules into peptides to produce proteins. [1] [2] Its descendants include the last universal common ancestor (LUCA) and every modern cell.
The court called the idea of Brahmin families descending from an unbroken line of common ancestors as indicated by the names of their respective gotras "impossible to accept." The court consulted relevant Hindu texts and stressed the need for Hindu society and law to keep up with the times, emphasizing that notions of good social behavior and ...
The Y-chromosomal most recent common ancestor is the most recent common ancestor of the Y-chromosomes found in currently living human males.. Due to the definition via the "currently living" population, the identity of a MRCA, and by extension of the human Y-MRCA, is time-dependent (it depends on the moment in time intended by the term "currently").
