science

It makes zero sense to bring back extinct species who have zero chance of surviving the current and future environment.

~~I agree that's a horrible idea but I doin't think anyone is actually proposing that.~~

~~For me the question is, is there enough scientific value to be gained by "de-extincting" these ancient creatures to justify keeping them in a controlled environment for study.~~

edit:

never mind, i was wrong.

Colossal’s landmark de-extinction project will be the resurrection of the woolly mammoth - or more specifically a cold-resistant elephant with all of the core biological traits of the woolly mammoth. It will walk like a woolly mammoth, look like one, sound like one, but most importantly it will be able to inhabit the same ecosystem previously abandoned by the mammoth’s extinction.
