However, in general, it is impossible to identify the exact MRCA of a large set of individuals, but an estimate of the time at which the MRCA lived can often be given. Such time to most recent common ancestor (TMRCA) estimates can be given based on DNA test results and established mutation rates as practiced in genetic genealogy, or by reference to a non-genetic, mathematical model or computer simulation. In organisms using sexual reproduction, the matrilineal MRCA and patrilineal MRCA are the MRCAs of a given population considering only matrilineal and patrilineal descent, respectively. The MRCA of a population by definition cannot be older than either its matrilineal or its patrilineal MRCA. In the case of Homo sapiens, the matrilineal and patrilineal MRCA are also known as "Mitochondrial Eve" (mt-MRCA) and "Y-chromosomal Adam" (Y-MRCA) respectivelyThe age of the human MRCA is unknown. It is no greater than the age of either the Y-MRCA or the mt-MRCA, estimated at around 200,000 years. Unlike in pedigrees of individual humans or domesticated lineages where historical parentage is known, in the inference of relationships among species or higher groups of taxa (systematics or phylogenetics), ancestors are not directly observable or recognizable. They are inferences based on patterns of relationship among taxa inferred in a phylogenetic analysis of extant organisms as dubbed the "tree of life". This involves inference of ages of divergence for all hypothesized clades; for example, the MRCA of all Carnivora (i.e. the MRCA of "cats and dogs") is estimated to have diverged some 42 million years ago (Miacidae) The concept of the last common ancestor from the perspective of human evolution is described for a popular audience in The Ancestor's Tale by Richard Dawkins (2004). Dawkins lists "concestors" of the human lineage in order of increasing age, including hominin (humanbchimpanzee), hominine (humanbgorilla), hominid (humanborangutan), hominoid ------------------------------ End of alt.music.moxy-fruvous digest V14 #14116 ***********************************************
