Study finds that genes responsible for autoimmune diseases may have originated in the Bronze age

Researchers at the University of Oxford have found a likely tie between genes formed during the early stages of animal husbandry 5,000 years ago to current day autoimmune diseases. Genetics which now show to increase the likelihood of developing autoimmune diseases like multiple sclerosis appear to be a genetic variant of the same DNA sequence that protected early farmers from contracting diseases from their animals and other people as population densities increased.
