Interest in the origins of human populations and their migration routes has increased greatly in recent years. A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPS , that uses mutations to predict time in order to date the ancient DNA. At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating.

Silver-gilt object, announced by British Museum, was discovered in a field near Pontefract last year. Delicately crafted using silver-gilt, it shows a praying knight emerging from a snail on the back of a goat and may be an example of 13th-century Yorkshire satire. Precisely what the joke was may never be known. The best guess is that its owner commissioned it and wore it as a badge, or attached it to a leather belt or strap. Nenk said snails were often depicted in the margins of medieval illuminated manuscripts, thought to symbolise cowardice. Nenk said satire was often found in medieval material culture, with one of the most popular visual gags being a monkey, in place of a doctor, examining a flask of urine for its clarity and colour — the go-to method for diagnosing medieval ailments.

An arranged marriage is the union of a man and a woman which is brought about by someone other than the bride and groom. Historically, it was the primary way in which future spouses were introduced, and arranged marriages still are a fairly common practice in certain parts of the world today. Learn all about the history of arranged marriage, how they have evolved over time, and the advantages and disadvantages to marrying someone you hardly know.
Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.
