=== TL;DR === | |||
Things we didn’t find: | |||
* Evidence of alien origin. | |||
* Evidence that the mummies are human (or any other specific species). | |||
* Evidence of genetic engineering. | |||
* Evidence of faked samples. | |||
Things we did find: | |||
* Three high-throughput Next-Generation Sequencing sample run files showing high levels of contamination and degradation, completely consistent with ancient DNA extracted after lying for hundreds or thousands of years in a cave. | |||
* Reasonable statistical evidence that the sample run files were not computationally faked. | |||
* Samples largely dominated by prokaryotic DNA (bacteria and archaea) and unclassified reads. | |||
* Varying percentages of human-aligned DNA in all samples. | |||
* A surprising and perplexing result for the Ancient0003 sample with very strong (>95%) alignment to the human genome: mitochondrial DNA most closely related in our investigation to a modern population in Myanmar, not indigenous Peruvian, broader indigenous American, or European. | |||
* Interesting avenues for further exploration. | |||

Three ancient mummified remains, linked to the Nazca mummies, have prompted speculation about their origins, particularly in communities interested in the possibility of extraterrestrial life. We analyzed the DNA of these three remains to see what genetic information might be there. | Three ancient mummified remains, linked to the Nazca mummies, have prompted speculation about their origins, particularly in communities interested in the possibility of extraterrestrial life.
