"Unearthing Down Syndrome: Ancient DNA Reveals Genetic Signatures in Historic Humans"
A new study analyzing the DNA of almost 10,000 people from ancient and pre-modern societies has identified 6 cases of Down syndrome in past human populations, with one specimen dating back 5,500 years. The research aims to trace the origins of these individuals and understand how prehistoric societies treated people with Down syndrome and other rare conditions. The study, led by researchers at the Max Planck Institute for Evolutionary Anthropology, utilized a new statistical model to identify these cases and shed light on the treatment and integration of individuals with genetic conditions in ancient communities.

Unveiling Ötzi the Iceman: Dark-Skinned and Bald, His Origins Traced to Turkey
Originally Published 2 years ago — by The Guardian
A new study analyzing the genome of Ötzi the Iceman, the mummified corpse found in the Italian Alps, reveals that he had a receding hairline, dark eyes, dark skin tone, and few or no freckles. The study also challenges previous findings about his ancestry, suggesting that Ötzi's ancestors came from Anatolia and had little genetic mixing with hunter-gatherer groups. The research provides a better understanding of Ötzi's physical appearance and highlights the advancements in DNA sequencing technology.
