It's pretty amazing: bones from thousands of years ago yielded traces of malaria parasites. Disease historians are surprised by what they've learned.In modern times, malaria is thought of as a tropical disease but evidence from ancient bones reveals a different narrative. Above: In Ambowuha, Ethiopia, Birtukan Demissie and her siblings are protected from mosquitoes that carry the disease with a bed net. Joining them is the family cat.
That alone was a “big surprise,” Krause said. It’s hard enough to find human DNA in a bone sample that’s thousands of years old, “but what's the chance to find the pathogen that was present in the person when he died?” Another surprise: scientists used to think P. vivax was older than P. falciparum – but so far, there’s no evidence of that.The relatively new field of archaeogenetics – the study of ancient DNA – has previously examined the history of bubonic plague.
