"Iron Age Infant with Down's Syndrome Identified Through Advanced DNA Testing"

Researchers have identified an Iron Age infant with Down's syndrome and the first prehistoric person with mosaic Turner syndrome using a new DNA testing method that measures the amount of chromosomes in ancient human cells more precisely. The study, conducted by the University of York, the Francis Crick Institute, the University of Oxford, and Oxford Archaeology, revealed that these chromosomal abnormalities have been present in human history for over 2,000 years. The individuals tested lived across various time periods, and the research sheds light on how sex, gender, and diversity were perceived in past societies.
