The actual study can be read at https://www.nature.com/articles/s42003-022-03777-z.pdf.

Methodology is given towards the end of the paper. In particular: "Variants [...] were compared with a normal dataset [...] created with sequencing data from seven young, healthy individuals."

They should have taken samples of the same age. Mutations accumulate over the entire life of the organism.

The full experiment, using old samples that degrade also, looks badly designed to point to a predefined desired answer. It somehow ended in Nature, probably because "authority appeal"
