“That guy” is Jack Horner, one of the most famous paleontologists of the late 20th century. He was also the paleontology advisor for Jurassic Park. I’m be had the pleasure of meeting him a couple times.If I remember correctly from the podcast spouting off Mammoth DNA facts, I think they have a composite genome in total across all samples of some paltry sum, 8-11%. Just enough fragments and just enough knowledge of the complete elephant genome today to know how to do CRISPR on an elephant egg to make it a hairy, humpy elephant.
I'm sure that cloned blackfooted ferret was based upon a perfect sample extracted under sterile conditions versus a recovery of a decaying carcass. The contamination after a few hours post mortem is problematic because the sample then incorporates DNA of fungal, plant, and bacterial elements along with potential insect.
The dream of extinct species walking the earth is one that I've thought would be marvelous ever since Michael Crichton's book came out. Unfortunately, we don't even have the tech to bring back the 6-7 modern-era extinct North American Elk species, much less to bring back a 6000-10000 year old dead mammoth.
This guy does a pretty good job of explaining what is really taking place when someone talks about bringing back an extinct species in his "Dino-Chicken" Presentation.

He came and gave his chicken talk when his book came out at the museum I work for. The work is definitely interesting. Moreso in that it demonstrates the latent non avian dinosaur traits still present in modern bird genomes.
Technically birds are dinosaurs so any creature you developed from chickens would still count. Though by playing semantics, hunting dove counts as hunting dinosaurs without all the labwork! It just wouldn’t be a Velociraptor mongolianensis or what have you, as you correctly stated earlier.
Anyhow, I completely agree that any claims to attempt to produce a mammoth are overstated. They also ignore some basic ecological facts when it comes to rewilding. I would hazard to guess that most, if not all, mammoths preserved in the tundra are woolly mammoths. Wooly mammoths ranged in northern latitudes (hence their occasional preservation in ice) however the correct mammoth to rewild the US with is the Colombian mammoth which was adapted to a warmer, more Southernly range.
All this talk of rewilding with cloned mammoths is about the wrong mammoth!
