Milk from domestic cows has been a valuable food source for over 8,000 years, especially in lactose-tolerant human societies that exploit dairy breeds. We studied geographic patterns of variation in genes encoding the six most important milk proteins in 70 native European cattle breeds. We found substantial geographic coincidence between high diversity in cattle milk genes, locations of the European Neolithic cattle farming sites (>5,000 years ago) and present-day lactose tolerance in Europeans… 
The Ancient Roots of Milk Consumption and its Genetic Dependence
Milk from domestic cows has been a valuable food source for over 8,000 years. However, humans can take full advantage of this food source only if adults have the ability to tolerate milk as a food.
Invited review: milk protein polymorphisms in cattle: effect on animal breeding and human nutrition.
The gene-culture coevolution between cattle milk protein genes and human lactase genes, which has been recently highlighted, is impressive proof of the nonrandom occurrence of milk protein genetic variation over the centuries.
Ancient DNA Analysis Reveals High Frequency of European Lactase Persistence Allele (T-13910) in Medieval Central Europe
DNA extracted from the dentine of 36 individuals excavated at a medieval cemetery in Dalheim, Germany suggests that genetic lactase persistence likely reached modern levels before the historic population declines associated with the Black Death, thus excluding plague-associated evolutionary forces in the rise of lactases persistence in this region.
Genetic diversity in farm animals--a review.
This work has summarized genetic diversity within and across breeds and a reconstruction of the history of breeds and ancestral populations for cattle, yak, water buffalo, sheep, goats, camelids, pigs, horses, and chickens.
Characterization of Casein Gene Complex and Genetic Diversity Analysis in Indian Goats
The Indian goats exhibited αS1-CN (CSN1S1) A allele in higher frequency in all the breeds indicating the higher casein yield in their milk, demonstrating genetic diversity and breed fragmentation.
Whole-Genome Sequencing Reveals Lactase Persistence Adaptation in European Dogs
The genetic basis of convergent evolution between humans and dogs with respect to diet is uncovered, emphasizing the import of the dog as a biomedical model for studying mechanisms of the digestive system.
On the Evolution of Lactase Persistence in Humans.
Lactase persistence-the ability of adults to digest the lactose in milk-varies widely in frequency across human populations. This trait represents an adaptation to the domestication of dairying
Dual Origins of Dairy Cattle Farming – Evidence from a Comprehensive Survey of European Y-Chromosomal Variation
It is proposed that the homogeneous Y1 and Y2 regions reflect founder effects associated with the development and expansion of two groups of dairy cattle, the pied or red breeds from the North Sea and Baltic coasts and the spotted, yellow or brown breeds from Switzerland, respectively.
Population Genetics of Lactase Persistence and Lactose Intolerance
The phenotypic polymorphism and the evidence that the genetic trait involves regulation of expression of the lactase gene and is caused by multiple independent mutations that have reached high frequencies in different populations, because of the benefits of drinking milk are described.
Candidate genes for control of cattle milk production traits
The allelic variants of candidate genes participating in the metabolic processes and defining their functional specificity to control the important economic traits, including the milk production, are not reliable bioindicators required for the early prediction in this case.


Marker-derived phylogeny of European cattle supports demic expansion of agriculture.
Positive partial correlations between genetic distance and time elapsed since introduction of farming while keeping geographical distances constant, and regular patterns over thousands of kilometers indicate that large-scale cattle population movements together with human migration from the Near East into Europe across the Balkans are the most likely explanation for the genetic distances observed in data.
Nucleotide sequence evolution at the kappa-casein locus: evidence for positive selection within the family Bovidae.
The pattern of nucleotide substitution in kappa-casein sequences for distantly related bovid taxa demonstrates that positive selection has accelerated their divergence at the amino acid sequence level.
Haplotype diversity of the myostatin gene among beef cattle breeds
Muscular hypertrophy (namely nt821(del11)) was mainly spread in different waves from northern Europe milk purpose populations in most breeds; however, other mutations arose in a single breed, were highly selected and have since scarcely evolved to other populations.
Genetic evidence for Near-Eastern origins of European cattle
The limited ranges of the wild progenitors of many of the primary European domestic species point to their origins further east in Anatolia or the fertile crescent. The wild ox (Bos primigenius),
Early Weaning of Neolithic Domestic Cattle (Bercy, France) Revealed by Intra-tooth Variation in Nitrogen Isotope Ratios
Results suggest that the Neolithic calves were weaned early, which could reflect either a shorter lactation for Neolithic cows, or early weaning imposed by the herder in order to reserve a bigger proportion of milk production for human consumption.
A microsatellite survey of cattle from a centre of origin: the Near East
It was possible to demonstrate that Near Eastern cattle exhibited significantly higher levels of allelic diversity than breeds from other regions, which is consistent with the view that this region represents a primary domestication centre for Bos taurus cattle.
Genetic structure of seven European cattle breeds assessed using 20 microsatellite markers.
It is demonstrated that a simple allele-sharing genetic distance parameter can be used to construct a dendrogram of relationships among animals and reflects an extensive underlying kinship structure, particularly for the Swiss Simmental breed and four breeds originating from the British Isles.
Haplotype Diversity and Linkage Disequilibrium at Human G6PD: Recent Origin of Alleles That Confer Malarial Resistance
The hypothesis that malaria has had a major impact on humans only since the introduction of agriculture within the past 10,000 years is supported and the locus of “A−” and ”Med” mutations provides a striking example of the signature of selection on the human genome.
Genetic analysis of host-parasite coevolution in human malaria.
Combined genetic, immunological and mathematical analysis of host and parasite variants in natural populations can identify some mechanisms driving host-parasite coevolution.
Direct demonstration of milk as an element of archaeological economies
The stable carbon isotope (delta13C) compositions of individual fatty acid components of remnant fats preserved in archaeological pottery vessels show that dairying was a component of archaeological
