Mitochondrial DNA and human evolution
TLDR
All these mitochondrial DMAs stem from one woman who is postulated to have lived about 200,000 years ago, probably in Africa, implying that each area was colonised repeatedly. Expand
Mitochondrial DNA and two perspectives on evolutionary genetics
This essay reviews comparative studies of animal mitochondrial DNA (mtDNA), with emphasis on findings made and ideas developed at Berkeley. It argues that such studies are bringing together twoExpand
Monophyletic origin of Lake Victoria cichlid fishes suggested by mitochondrial DNA sequences
TLDR
This work sequenced up to 803 base pairs of mitochondrial DNA from 14 representative Victorian species and 23 additional African species to study the 'flock' of cichlid fishes in Lake Victoria. Expand
Mitochondrial DNA sequences of primates: Tempo and mode of evolution
TLDR
Genealogical analysis of the sequence differences supports the view that the human lineage branched off only slightly before the gorilla and chimpanzee lineages diverged and strengthens the hypothesis that humans are more related to gorillas and chimpanzees than is the orangutan. Expand
Evolution of the cytochromeb gene of mammals
TLDR
Comparisons of these cytochromeb sequences support current structure-function models for this membrane-spanning protein, including that part of the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix. Expand
Calibration of mitochondrial DNA evolution in geese
TLDR
Fossil evidence suggests that these two groups of geese had a common ancestor 4–5 million years ago, and the mean rate of sequence divergence in goose mitochondiral DNA is not far from 2% per million years, the value in mammals. Expand
Paternal inheritance of mitochondrial DNA in mice
TLDR
Paternally inherited mtDNA molecules have now been detected in mice at a frequency of 10−4, relative to the maternal contributions, which provides a mechanism for generating heteroplasmy and may explain mitochondrial disorders exhibiting biparental transmission. Expand
DNA sequences from the quagga, an extinct member of the horse family
TLDR
Dried muscle from a museum specimen of the quagga, a zebra-like species that became extinct in 1883, is examined, and DNA was extracted in amounts approaching 1% of that expected from fresh muscle, and that the DNA was of relatively low molecular weight. Expand
Molecular Evolution in Drosophila and the Higher Diptera II. A Time Scale for Fly Evolution
TLDR
The steadiness of the rate of evolutionary change in a larval hemolymph protein, LHP, in numerous Drosophila species is examined, and an explicit description of a procedure for calculating the absolute value of the mean rate of evolution change in this protein is given. Expand
ABRUPT CLINE FOR SEX CHROMOSOMES IN A HYBRID ZONE BETWEEN TWO SPECIES OF MICE
TLDR
The limited flow of both X‐ and Y‐specific alleles suggest that sex chromosomes have played an important role in Mus speciation and may contribute to hybrid breakdown between two species. Expand
