DNA markers reveal the complexity of livestock domestication
TLDR
By comparing mitochondrial and nuclear DNA sequences of modern breeds with their potential wild and domestic ancestors, new insights are gained into the timing and location of domestication events that produced the farm animals of today.Abstract:
A series of recent genetic studies has revealed the remarkably complex picture of domestication in both New World and Old World livestock. By comparing mitochondrial and nuclear DNA sequences of modern breeds with their potential wild and domestic ancestors, we have gained new insights into the timing and location of domestication events that produced the farm animals of today. The real surprise has been the high number of domestication events and the diverse locations in which they took place — factors which could radically change our approach to conserving livestock biodiversity resources in the future.read more

Chapter 2. Fasciola, lymnaeids and human fascioliasis, with a global overview on disease transmission, epidemiology, evolutionary genetics, molecular epidemiology and control.
TL;DR: In this paper, the origins and geographical spread of F. gigantica and F. hepatica were investigated by means of complete sequences of ribosomal deoxyribonucleic acid (rDNA) internal transcribed spacer (ITS)−2 and ITS−1 and mitochondrial cox1 and nad1 from areas with only one fasciolid species.

Domestic-animal genomics: deciphering the genetics of complex traits
TL;DR: When the genome sequences of domestic animals become available the identification of the mutations that underlie the transformation from a wild to a domestic species will be a realistic and important target.

TL;DR: Different clades may originate from different regions, such as Yunnan, South and Southwest China and/or surrounding areas (i.e., Vietnam, Burma, and Thailand), and the Indian subcontinent, which support the theory of multiple origins in South and Southeast Asia.

Median-joining networks for inferring intraspecific phylogenies.
TL;DR: A method for constructing networks from recombination-free population data that combines features of Kruskal's algorithm for finding minimum spanning trees by favoring short connections, and Farris's maximum-parsimony (MP) heuristic algorithm, which sequentially adds new vertices called "median vectors", except that the MJ method does not resolve ties.

Population growth makes waves in the distribution of pairwise genetic differences.

TL;DR: In this article, the authors present histograms showing the relative frequencies of pairs of individuals who differ by i sites, where i = 0, 1,.... In this distribution an episode of growth generates a wave that travels to the right, traversing 1 unit of the horizontal axis in each 1/2u generations, where u is the mutation rate.
Journal ArticleDOI
Rapid evolution of animal mitochondrial DNA.
TL;DR: The rate of evolution of the mitochondrial genome appears to exceed that of the single-copy fraction of the nuclear genome by a factor of about 10 and is likely to be an extremely useful molecule to employ for high-resolution analysis of the evolutionary process.
