In Britain in the late 1880s, two pop cultural icons had an extraordinary meeting: one, Ally Sloper, the fictional star of comic books and stage productions and the other Jack the Ripper, the real-life serial killer who was instantly fictionalised on page and stage as the bogeyman of the moment. The aim here is to explore the way in which this dynamic developed, with a focus on a single issue of 'Ally Sloper’s Half-Holiday' (October 20, 1888), which appeared at the point in time when it was first realised that the killings were being done by a lone individual, and when panic was at its peak. What was at stake politically in the comic’s reaction? What can it tell us about Victorian attitudes to fear, death, and poverty? About the status of women? Finally, about law and order, and the social contract that existed between citizen and police?
Archaeological evidence indicates that pig domestication had begun by ∼10,500 y before the present (BP) in the Near East, and mitochondrial DNA (mtDNA) suggests that pigs arrived in Europe alongside farmers ∼8,500 y BP. A few thousand years after the introduction of Near Eastern pigs into Europe, however, their characteristic mtDNA signature disappeared and was replaced by haplotypes associated with European wild boars. This turnover could be accounted for by substantial gene flow from local European wild boars, although it is also possible that European wild boars were domesticated independently without any genetic contribution from the Near East. To test these hypotheses, we obtained mtDNA sequences from 2,099 modern and ancient pig samples and 63 nuclear ancient genomes from Near Eastern and European pigs. Our analyses revealed that European domestic pigs dating from 7,100 to 6,000 y BP possessed both Near Eastern and European nuclear ancestry, while later pigs possessed no more than 4% Near Eastern ancestry, indicating that gene flow from European wild boars resulted in a near-complete disappearance of Near East ancestry. In addition, we demonstrate that a variant at a locus encoding black coat color likely originated in the Near East and persisted in European pigs. Altogether, our results indicate that while pigs were not independently domesticated in Europe, the vast majority of human-mediated selection over the past 5,000 y focused on the genomic fraction derived from the European wild boars, and not on the fraction that was selected by early Neolithic farmers over the first 2,500 y of the domestication process.
