Colossal, the company founded to try to restore the mammoth to the Arctic tundra, has also decided to tackle a number of other species that have gone extinct relatively recently: the dodo and the thylacine. Because of significant differences in biology, not the least of which is the generation time of Proboscideans, these other efforts may reach many critical milestones well in advance of the work on mammoths.
[...]
Colossal has branched out from its original de-extinction mission to include efforts to keep species from ever needing its services. In the case of marsupial predators, the de-extinction effort is incorporating work that will benefit existing marsupial predators: generating resistance to the toxins found on the cane toad, an invasive species that has spread widely across Australia.
[...]
For the de-extinction process, the goal would be to ensure that the thylacine could survive in the presence of the cane toad. But Colossal has also begun a conservation effort, called the Colossal foundation, that aims to keep threatened species from needing its services in the future.
[...]
Colossal has obtained a nearly complete genome sequence from a thylacine sample that was preserved in ethanol a bit over a century ago. According to Pask, this sample contains both the short fragments typical of older DNA samples (typically just a few hundred base pairs long), but also some DNA molecules that were above 10,000 bases long. This allowed them to do both short- and long-read sequencing, leaving them with just 45 gaps in the total genome sequence, which the team expects to close shortly.
[...]
The final thing the company announced was that it was working on getting dunnart embryos to develop outside of the womb.
[...]
At this point, they've got immature neural cells and have started forming the cells that will go on to form muscles and the vertebrae. But many critical events need to happen in the remaining one-third of the pregnancy, and Colossal isn't ready to talk about what goes wrong to stop development here.
[...]
Hopefully, over time, the company will continue to submit some of its work to peer-reviewed journals.In the meantime, the clear indications of progress suggest that some of the unique features of the marsupials—relatively rapid generation times, accessible reproductive system, and many similarities to well-studied placental mammals—are helping this project move ahead at a reasonably rapid clip.

What about de-extinction of aboriginal human population in Tasmania and Australia and Indigenous human population in North America?

Why limit yourself? Bring them all back! Bringing back Cro-Magnon, the Homo Habilis, the Homo Erectus or even the Homo Neanderthalensis. We wiped them out before, we can do it again!
I'm still waiting for T-rex or any dino. Preferably not a predator or one of the carnivorous once. Perhaps even the Aurochs. I want auroch-burgers!

Also cthonians, shoggoths, nightgaunts, tcho-tcho, shantak, mi-go, and byakhee. May as well make it exciting and interesting.

But they are not extinct. They are just sleeping with Big C. Or hanging out on Pluto.

Apparently, someone objected to the adjective "asshole" here.
Which, as someone said to me a long time ago, "if someone is acting stupid, you call them an 'asshole'. But often they're misunderstand that you're chastising them for acting stupid and think you're just being mean."
The point of the multiple links was to show GP's stupidity and not to troll. Because the Maori, Australian Aborigines and American First Peoples/those that migrated to the Americas either across the Bering land bridge or by sea, dead or not, are so closely related to other humans, that there is (at least from a genetic standpoint) no distinction between those groups and other extant human populations.
As such, they are not genetically extinct at all.
Perhaps an argument could be made that their *cultures* are extinct, but that's not the same thing at all.
and so I repeat myself -- asshole!

And in that vein, you can't birth a culture. It takes years of knowledge transfer from someone already living in the culture. Maybe we could learn enough about some extinct cultures that we could create AI humanoid robots to raise some humans in the culture. But it'll take a lot more work than birthing extinct species would.

"Asshole" implies malevolence, particularly on a continuing basis. This is not in evidence here. "Ignoramus" is more likely and less insulting. The adjective "cheeky" might also apply.
