Спустя много недель этот пост принесет некоторые результаты в эти выходные. И, насколько я понял, ДНК не соответствует людям, кто-нибудь может объяснить лучше?

[«“Since the comment thread have people speculating allow me to explain.

They took 7 samples 3 tissue samples and 4 dna samples from the mummies.](https://www.reddit.com/r/AlienBodies/comments/171xkei/comment/k3y37bd/?utm_source=share&utm_medium=web2x&context=3) Only 3 samples were found to be viable enough to continue this would be CEN4GEN-Ancient0002, CEN4GEN-Ancient003, and CEN4GEN-Ancient004.
Ancient0002 had a fragment size of 398 base pairs which isn’t a lot but enough to find out which animal it is. Ancient 0003 had 515, and Ancient0004 had 423. These are really tiny fragments of DNA.
They really did bring out all the stops for this, it’s really pretty cool shit.
They compared the amplified sequenced DNA data to human DNA for quick verification to find out if any of the 3 surviving samples were human or not. Each sequence had a quarter fragment picked randomly and were mapped using best available version of a human genome reference. Which GRCH38 release 93 was used.
The result showed that Ancient0002 had a human DNA content of 14.2924%, Ancient0003 had a 97.6894% human DNA content, and that Ancient0004 had a human DNA content of 15.2589%. This is to say the percentage of that random quarter of DNA that was used to compare matched with that many sequenced base pairs in the human genome reference they used to compare. SO Ancient0003 is definitely probably human.
As a control they did the same process to 100% known human DNA and got the same expected result that corelated to Ancient003’s result confirming that yes it’s probably human.
Subsequent testing for overlapped pairs proved that Ancient003 is from a human origin with a 95.07% match. Further testing suggested that Ancient0003 came from a human male as there was evidence of X and Y chromosomes.
Ancient0004 and Ancient0002 were further tested by comparing the dna sequences to known dna sequences found in public data bases that included bacteria, virus, plasmids, phages, fungi, plastid, diatoms, human, bos taurus, h penzbergensis, phaseolus vulgaris, the complete genome of Lotus Japonicus chloroplast, Canis Lupus familiaris olfactory receptor family 9 subfamily 5 pseudogene on chromosome 25, Vigna Radiata mitochondrion, complete genome, Millettia Pinnata chloroplast, complete genome, Curvibacter Lanceolaatus whole shotgun sequence. Asinibacterium sp OR53 scaffold1, whole genome shotgun sequence.
And a whole lot of others. Including animals such as skate, zebra finch, Goat, Horse, Platypus, Dog, Mule, and Goode’s thornscrub tortoise.
27% of the DNA from Ancient0002 and 90% of the dna from Ancient0004 could not be mapped to DNA from the database of samples used.
Further refinement of Ancient0002 and Ancient0004 and re comparing them to known organisms in the selected database resulted in noted similarities with known organisms. They weren’t human but they weren’t exactly alien either so they wanted to know just how similar the DNA samples were to known organism.
So they compared the DNA samples with an even larger more robust database which they used the NCBI nt database. Which is basically a database of every living thing on the planet’s genome. If it exists a chunk of DNA is in there fully sequenced.
The results were fascinating, 54% of Ancient002 is unclassified, and 76% of Ancient004 was unclassified.
However as the conclusion explains there is a lot of room for error and while the NCBI nt database is extensive it’s not complete. So until further notice Ancient002 and Ancient004 are unknown. even though they both share plenty of similarities with known organisms.”
