The Mitochondrial Eve can change, when a mother-daughter line comes to an end. It follows from the definition of Mitochondrial Eve that she had at least two daughters who both have unbroken female lineages that have survived to the present day. In every generation mitochondrial lineages end – when a woman with unique mtDNA dies with no daughters.
In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the anatomically modern human (Homo sapiens) mtDNA phylogenetic tree. As such, it represents the most ancestral mitochondrial lineage of all currently living modern humans, also dubbed "Mitochondrial Eve". Its two sub-clades are L1-6 and L0.
The region in Africa where Tishkoff found the greatest level of mitochondrial diversity (green) and the region Behar et al. postulated the most ancient division in the human population began to occur (light brown) L0 is one of two branches from the most recent common ancestor (MRCA) for the shared human maternal lineage. The haplogroup consists ...
The hypothetical woman at the root of all these groups (meaning just the mitochondrial DNA haplogroups) is the matrilineal most recent common ancestor (MRCA) for all currently living humans. She is commonly called Mitochondrial Eve. The rate at which mitochondrial DNA mutates is known as the mitochondrial molecular clock. It is an area of ...
Map of early diversification of modern humans according to mitochondrial population genetics (see: Haplogroup L). The first lineage to branch off from Mitochondrial Eve was L0. This haplogroup is found in high proportions among the San of Southern Africa and the Sandawe of East Africa. It is also found among the Mbuti people.
The Seven Daughters of Eve [1] is a 2001 semi-fictional book by Bryan Sykes that presents the science of human origin in Africa and their dispersion to a general audience. [2] Sykes explains the principles of genetics and human evolution , the particularities of mitochondrial DNA, and analyses of ancient DNA to genetically link modern humans to ...
"Mitochondrial Eve" is a science-fiction novelette by Australian writer Greg Egan, first published in Interzone #92 in February 1995. The novelette was included in the anthology The Best of Interzone in 1997 and in the collection Luminous in 1998.
The human mitochondrial molecular clock is the rate at which mutations have been accumulating in the mitochondrial genome of hominids during the course of human evolution. The archeological record of human activity from early periods in human prehistory is relatively limited and its interpretation has been controversial.
