Researchers analyzed the DNA of almost 5,000 ancient humans and created the worlds largest ancient human gene bank. By comparing ancient and modern DNA, they discovered the historical spread of genes and diseases across populations. The findings provide new insights into neurodegenerative diseases like multiple sclerosis and explain the height differences between northern and southern Europeans. Multiple sclerosis affects 2.3 million people worldwide and is twice as common in women. The cause is unclear, but it may involve genes, smoking, and low vitamin D levels.
