To determine whether DNA survives and can be recovered from the remains of extinct creatures, we have examined dried muscle from a museum specimen of the quagga, a zebra-like species (Equus quagga) that became extinct in 1883 (ref. 1). We report that DNA was extracted from this tissue in amounts approaching 1% of that expected from fresh muscle, and that the DNA was of relatively low molecular weight. Among the many clones obtained from the quagga DNA, two containing pieces of mitochondrial DNA… Expand
Mitochondrial DNA of the extinct quagga: Relatedness and extent of postmortem change
TLDR
It is estimated that the mean rate of sequence divergence between horse and zebra mitochondrial DNAs is similar to that in other mammals, i.e., roughly 2% per million years. Expand
Mitochondrial DNA from Myotragus balearicus, an extinct bovid from the Balearic Islands.
TLDR
Phylogenetic comparison with orthologous sequences from supposedly related extant genera from the Caprinae subfamily suggests that Myotragus is related to some of these species, however, the real phylogenetic position of MyotRAGus is difficult to assess, due to the lack of resolution of the present molecular study.

Genetic characterization of horse bone excavated from the Kwakji archaeological site, Jeju, Korea.
TLDR
The molecular phylogenetic characteristics of the horse bone that was excavated from the Kwakji archaeological site showed that some horse breeds may have existed on Jeju Island, Korea before Mongolian horses were introduced. Expand
Genetic analyses from ancient DNA.
TLDR
The precautions and criteria necessary to ascertain to the greatest extent possible that results represent authentic ancient DNA sequences are discussed, which highlight some significant results and areas of promising future research. Expand
A rapid loss of stripes: the evolutionary history of the extinct quagga
TLDR
It is shown that the quagga displayed little genetic diversity and very recently diverged from the plains zebra, probably during the penultimate glacial maximum, which emphasizes the importance of Pleistocene climate changes for phylogeographic patterns in African as well as Holarctic fauna. Expand
Human evolution: The Neanderthal in the family
TLDR
In the past year, researchers have unveiled the two oldest genomes on record: those of a horse that had been buried in Canadian permafrost for around 700,000 years, and of a roughly 400,000-year-old human relative from a Spanish cavern. Expand
Chloroplast DNA sequence from a Miocene Magnolia species
TLDR
The extraction of DNA from fossil leaf samples from the Miocene Clarkia deposit, the amplification of an 820-base pair DNA fragment from the chloroplast gene rbcL from a fossil of the genus Magnolia, and its subsequent sequencing extend the ability to analyse ancient DNA and may open new avenues into problems in palaeobotany, biogeography, and in the calibration of mutation rates. Expand
Mitochondrial DNA evolution in the genus Equus.
TLDR
The variation between species supports a divergence of extant lineages from a common ancestor approximately 3.9 Myr before the present, and trees constructed according to the parsimony principle indicate that the three extant zebra species represent a monophyletic group. Expand

TLDR
It is indicated that analysis of Miocene fossil DNA can be replicated, and can, therefore, open up the prospects for future development of the field of molecular palaeontology. Expand
Tempo and mode of sequence evolution in mitochondrial DNA of HawaiianDrosophila
TLDR
The mtDNAs of flies and mammals are alike in the shape of the curve relating the percentage of positions at which there are differences in protein-coding regions to the time of divergence, and the low percentage of hypervariable sites may be a consequence of a functional constraint associated with the low content of guanine and cytosine in fly mtDNA.

TLDR
It is proposed that the rapid evolution of mtDNA relative to nuclear DNA is due only to silent changes and that amino acid-altering substitutions accumulate in nuclear and mtDNA at comparable rates. Expand
Complete sequence of bovine mitochondrial DNA. Conserved features of the mammalian mitochondrial genome.

The bovine 12 S and 16 S Ribosomal RNA genes, when compared with those from human mitochondrial DNA, show conserved features that are consistent with proposed secondary structure models for the ribosomal RNAs. Expand
Sequence and organization of the human mitochondrial genome
TLDR
The complete sequence of the 16,569-base pair human mitochondrial genome is presented and shows extreme economy in that the genes have none or only a few noncoding bases between them, and in many cases the termination codons are not coded in the DNA but are created post-transcriptionally by polyadenylation of the mRNAs.
