There have been a lot of amazing and enlightening discoveries, about DNA, and especially the mitochondrial DNA, in the last 30 yrs. Most of them have been problematic for the theory of universal common descent. Reconciling the facts about genetics, with the beliefs about common descent has not been easy, and has given rise to hysterical dogmatism, among the True Believers in evolutionary theory.
I have gleaned a lot of information from this study by Ann Gibbons, and will refer to it often.
The small circles of DNA in mitochondria have been the favored tool for evolutionary and forensic studies since their sequence was unraveled in 1981. Unlike the DNA in the nucleus of the cell, which comes from both egg and sperm, an organism's mtDNA comes only from the mother's egg. Thus mtDNA can be used to trace maternal ancestry without the complicating effects of the mixing of genes from both parents. And every cell in the body has hundreds of energy-producing mitochondria, so it's far easier to retrieve mtDNA than nuclear DNA.
From Gibbons:
Regardless of the cause, evolutionists are most concerned about the effect of a faster mutation rate.
For example, researchers have calculated that "mitochondrial Eve"--the woman whose mtDNA was
ancestral to that in all living people--lived 100,000 to 200,000 years ago in Africa. Using the new
clock, she would be a mere 6000 years old.

I'll give you a summary, in layman's terms.
1. Mitochondrial DNA was discovered in the early 80s.
2. A 'flag', or correlation was discovered, showing descendancy from mother to daughter.
3. An estimate of dating, based on phylogeny (evolutionary tree assumptions) was made of 1 mutation every 10k yrs, or so.
4. MEASURED dating of mtDNA mutation, from multiple actual samples, produced a constant 800 yr rate.
5. Facts and scientific results have been poo pooed, in favor of preconceived beliefs, based only on assumptions of evolution.. aka, circular reasoning.
I am surprised, that the facts about mtDNA, in humans and other phylogenetic haplogroups, have not already introduced more doubt as to the 'settled science!' beliefs, regarding universal common descent. But dogmatic beliefs do not fade easily, and the dogma indoctrinated into modern 'science!' students are based on decades old teachings, and mandated Indoctrination.
It is too bad, that the hecklers here will not allow a rational, civil discussion about the significance and connotations of the mtDNA discoveries. Anything i say is pounced on & ridiculed without any consideration, or perusal. Standard debate practices of 'point/counter point' are abandoned in favor of fallacies and propaganda. Eventually I'll give up, which is the goal of the hecklers.
No scientific discussion allowed! Only the Approved State Beliefs can be repeated!
