The popular name "mitochondrial Eve", of 1980s coinage, [17] has contributed to a number of popular misconceptions. At first, the announcement of a "mitochondrial Eve" was even greeted with endorsement from young earth creationists, who viewed the theory as a validation of the biblical creation story.

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 title of the book comes from one of the principal achievements of mitochondrial genetics, which is the classification of all modern Europeans into seven groups, the mitochondrial haplogroups. Each haplogroup is defined by a set of characteristic mutations on the mitochondrial genome, and can be traced along a person's maternal line to a ...
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 ...
Mitochondrial Inheritance Patterns. In human mitochondrial genetics, there is debate over whether or not paternal mtDNA transmission is possible. Many studies hold that paternal mtDNA is never transmitted to offspring. [8] This thought is central to mtDNA genealogical DNA testing and to the theory of mitochondrial Eve.
Rebecca L. Cann (born 1951) is a geneticist who made a scientific breakthrough on mitochondrial DNA variation and evolution in humans, popularly called Mitochondrial Eve.Her discovery that all living humans are genetically descended from a single African mother who lived <200,000 years ago became the foundation of the Out of Africa theory, the most widely accepted explanation of the origin of ...
Mitochondrial DNA (mtDNA) is nearly immune to sexual mixing, unlike the nuclear DNA whose chromosomes are shuffled and recombined in Mendelian inheritance. Mitochondrial DNA, therefore, can be used to trace matrilineal inheritance and to find the Mitochondrial Eve (also known as the African Eve), the most recent common ancestor of all humans ...
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.
