Schistosomiasis in Ancient Egypt: The ‘AAA’ Debate
In 1910, Sir Marc Armand Ruffer (1859-1917), considered to be one of the founders of paleopathology, discovered the calcified eggs of Schistosoma haematobium in the kidneys of two mummies from Egypt’s 20 dynasty (1250-1000 BC). Since Ruffer’s discovery, debate has ensued over whether the medical papyri offer conclusive evidence that schistosomiasis, or bilharziasis, was known to the ancient Egy...
متن کاملAncient DNA from Human and Animal
Research on ancient DNA (aDNA) has the potential to enable molecular biologists and archeologists to decipher certain aspects of history by direct looking into the past. However, several major problems in this field limit the applicability of aDNA studies, most importantly contamination with modern DNA and postmortem DNA degradation. In this study we extracted and analyzed aDNA obtained from ~3...

متن کاملInsights into early pig domestication provided by ancient DNA analysis
Pigs (Sus scrofa) were first domesticated between 8,500 and 8,000 cal BC in the Near East, from where they were subsequently brought into Europe by agriculturalists. Soon after the arrival of the first domestic pigs in northern Europe (~4500 BC), farmers are thought to have started to incorporate local wild boars into their swine herds. This husbandry strategy ultimately resulted in the domesti...
متن کاملAncient DNA
Ancient DNA is a field of molecular evolutionary biology that usesDNA sequence data recovered frompoorly preserved organisms, usually deceased for hundreds to hundreds of thousands of years. Ancient DNA data can provide unique snapshots in time to better understand how populations and species evolve. The field was born in the early 1980s,when thefirst ancientDNAsequences were recovered from pre...
