According to CNN, in late 2019, a small piece of birch pitch (pictured above) was found by archeologists on Lolland, the fourth largest island of Denmark. A study uncovered a 5,700-year-old girl's entire genome and oral microbiome, marking the first time human genetic material has successfully been extracted from something besides human bones.
Nicknamed Lola, the young girl who chewed on the birch pitch had blue eyes, dark skin and dark hair. Her last meal included hazelnuts and mallard duck but no milk. She was lactose-intolerant, which serves to validate the theory that adults evolved the tolerance after dairy farming was introduced.
