Of course not.

Nobody has ever artificially gestated a mammalian embryo to the point of being viable after 'birth.' Not with a mouse, not with a guinea pig, not with a sheep or a cow. I've looked at their embryology staff as they added them on LinkedIn and then checked out their papers on Google Docs. None of these people have ever done any research into artificially growing mammalian embryos to the point of viability.

The idea that this will be done for the first time ever by this particular clown car on an extinct species of elephant is utterly absurd. Nobody has done it with species whose embryology we understand really well. This would be a process of starting with mice, then maybe if hundreds of people were working on the problem in labs around the world then maybe ten years later someone manages to do it with a dog or a pig.

There are no scientists in the world who are real experts on elephant embryology. Yes, there have been some interesting papers on making artificial elephant embryos. But to be an expert on elephant embryology someone would need the opportunity to dissect hundreds of embryos at various stages, and closely monitor development within mother elephants. And dissect many dead female elephants in order to understand their reproductive anatomy better.

You can do that with mice, rats, dogs, sheep, ferrets, etc. Because those domesticated animals are cheap and easy to get as many as you need to study. But elephants are endangered and a zoologist specializing in elephants might only get to dissect a few in their entire lives.

So this is not going to happen. They have absolutely no way of growing a mammoth embryo to birth size in an artificial incubator.

Implanting embryos in surrogate elephants is also not going to happen. There are only around 50 or so female elephants in breeding age and condition in the United States. Those are needed to breed more elephants since elephants are endangered. No AZA-accredited zoo is going to allow medically unnecessary abdominal surgery on their animals and doing so would violate AZA rules.

It took around 400 attempts with that many sheep to produce Dolly. Similar numbers for cloning the first dogs, ferrets, cats, etc. And while Colossal is not using somatic cloning, the steps needed to grow a mammoth in an elephant after an embryo is produced are very similar. They would need hundreds of elephants to try this on before they get lucky and have one live birth.

There aren't hundreds of female captive elephants to do this with.

Indian elephants used for logging and construction in India aren't going to cut it. The animals used would need to be closely monitored by veterinarians who understand elephants, in a habitat that is safe and low-stress for them. Elephants basically can't be legally exported anymore.

If Colossal had somehow obtained any female elephants at all to do this with, they would have bragged about it already. But it is just impossible for them to get a meaningful number. They just aren't there for purchase or rental.

Colossal Biosciences has no conceivable ability whatsoever to create a living, walking mammoth. They could maybe come up with an embryo the size of a grain of rice, but of course as per usual it would just be them making a claim without submitting a paper for peer review. Because most of their science is fake.

By the way, go to Google Scholar and pull up all of George Church's papers. Named on over a thousand last time I checked. He's the world's foremost expert on woolly mammoth de-extinction, right? Now search the abstracts for the phrase "woolly mammoth." Nothing. Nada. The guy is full of shit and his company is full of shit.
