Bringing back an extinct species - good idea?
The thylacine or tasmanian tiger was made extinct by humans less than 100 yrs ago. An attempt is apparently underway to resurrect it. I have always found its demise particularly tragic, and there is a film of the last known surviving one - https://www.youtube.com/watch?v=6gt0X-27GXM
I will follow this story with interest.

Interesting story, and one I’ll also be following.
My main concern is does the planet have the resources to support these animals making a comeback to lead any kind of natural life without too much human intervention?
Bringing back these animals would obviously make them targets for poachers and ‘collectors’. Wouldn’t we just be condemning them to a lifetime of being sad zoo exhibits?

Or even worse, resurrecting them from the dead to end up on the dinner table?
Woolly mammoths are making a comeback. Should we eat them?

Its already happened !
'Some' posters on this forum have been made 'extinct' and have now been resurrected

Fascinating stuff. I read the link and was surprised to see it's a marsupial.
I think it's a great idea. We've already lost far too many creatures due to man. The current deforestation of ancient forests for crops, and, even worse, to burn in a heartbeat in Drax's furnaces, is endangering even more native species. Add to this the devastating wildfires that are killing wildlife. How long before they become endangered or extinct? I can't even bear to think about what we might lose.
The worst species ever to live on this planet, is man.

It's just one example of convergent evolution. It occupies the same ecological niche in Australia as other top-level predators in other continents, tigers etc.
I would love to see its return, too.

It is interesting, and I think you're correct about their eventual worth.
It would be nice to see so many species alive and well in their natural habitat. But we'd just do the same to them.

…a harsh judgement though doubtless shared by many, if expressed in different ways.
Humankind is not the first species to endanger its existence by over-exploitation. However, humankind is unprecedentedly exceptional both in • having occupied (almost) every conceivable niche; and
• having developed ingenious technologies to spectacularly amplify its impact. Scientists tell as we are destroying environments and otherwise expediting species' extinction at an high and accelerating rate! We must drastically amend our destructive ways vis-à-vis existing species before we need think about reviving aleady extinct species.
"Granted, extinction is a phenomenon that occurs naturally, however it normally happens at a rate of 1 to 5 species every year. But, as scientists estimate, we are currently losing species 1,000-10,000 times faster than that, which means that literally tens of species are vanishing from the face of the Earth every day."

And it's not just animals, but also plants that we're losing....Some of which may well contain unique substances that could be of great value, e.g. in medicines, etc.

There is a gigantic seed bunker in Kew Gardens. It contains a stunning number of seeds from an incredible number of species. If they get a seed sample, really rare plants can be grown from them.

Think I heard about that, also another one under a mountain/in a mine or something. There are though plants I believe, whose seed has to be planted every few years, or they will fail.

Now that is something worth waiting for.

Convergent evolution is seriously flawed. Try divergent evolution. e.g Finch, Pigeon, Plants, and viruses etc.,.
"Recent evidence indicates that, contrary to a commonly held belief, T cells and B cells do not share an immediate common ancestor, but differentiate from myeloid-T and myeloid-B progenitors, respectively.149,150 If T cells and B cells are distantly related as suggested by these studies, it is not surprising if the two lineages of lymphoid cells diverged at an earlier stage in evolution than previously thought."151Masanori Kasahara, in Progress in Molecular Biology and Translational Science, 2010
