Mitochondrial DNA and human evolution
https://pubmed.ncbi.nlm.nih.gov/16124858/
Several unique properties of human mitochondrial DNA (mtDNA), including its high copy number, maternal inheritance, lack of recombination, and high mutation rate, have made it the molecule of choice for studies of human population history and evolution. Here we review the current state of knowledge concerning these properties, how mtDNA variation is studied, what we have learned, …

In contrast, the DNA in the nucleus is divided into 46 linear chromosomes (23 from each of our parents) that have an average length of more than 200 million base pairs. Each person's mitochondria ...
Mitochondrial DNA and the mysteries of human evolution ...
https://www.theguardian.com/science/2011/apr/25/mitochondrial-dna-human-evolution
DNA serves as a lineal history, a family album, a passport that bears the marks of both origin and journey. Mitochondrial DNA (mtDNA) is inherited only from the mother. Every few generations, a ...
Mitochondrial Evolution - PMC
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428767/
The genetic function of mitochondrial DNA (mtDNA) was first fully revealed by complete sequencing of the ∼16-kb mitochondrial genome from several mammalian species (Anderson et al. 1981, 1982; Bibb et al. 1981). This work established the paradigm that mtDNA encodes a small number (13 in mammals) of protein subunits of the mitochondrial electron transport chain and …
Mitochondrial DNA, a Powerful Tool to Decipher Ancient ...
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6562384/
This review will discuss the nature of mitochondrial DNA (mtDNA) and its levels in the cell, which are the key elements to consider when trying to achieve molecular identification in ancient and degraded samples. mtDNA sequence analysis has been appropriately validated and is a consistent molecular target for the examination of biological evidence encountered in …

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5282644/
Mitochondrial DNA (mtDNA) has been studied intensely for “its own” merit. Its role for the function of the cell and the organism remains a fertile field, its origin and evolution is an indispensable part of the evolution of life and its interaction with the nuclear DNA is among the most important cases of genome synergism and co-evolution.
