Permafrost shatters mammoth DNA instead of preserving it

HERE’S THE INTERESTING PART

Freezing a mammoth doesn't keep its genome perfectly intact like some sci-fi movie. The icy dirt violently degrades and chops the DNA into millions of biological puzzle pieces via complex taphonomic decay. Geneticists then have to painstakingly tape this microscopic garbage back together, proving that nature's freezer is actually a highly destructive meat grinder.
