Uncovering the Ancient Origins of Multiple Sclerosis in Western Europe

A new study published in Nature sheds light on the Neolithization process in western Eurasia, revealing distinct differences in the spread of farming between eastern and western populations. The ancestry of western Europeans was shaped by three major migrations, with the Yamnaya culture's expansion eradicating an invisible boundary. Additionally, genetic analysis suggests that the elevated risk for multiple sclerosis among northern Europeans originated from the Yamnaya nomads, possibly due to environmental and lifestyle factors.
