Why haven't we succeeded to clone (relatively) recently extinct species like the Tasmanian wolf, Dodo or Mammoth?

the closest we've ever come to bringing back a species was with the Pyrenean Ibex which failed, at what point in time will we able to master cloning of such creatures?

[EK !EKFQOBUFnQ No.4024643]

well probably never. it's really hard to get enough in tact undamaged dna to actually attempt something like this
you'd probably already need to have taken a sample prior to the animals extinction, and then use that to bring it back

Fuck animals - let's clone Jesus!

So? What can be more lulzy that science trolling all Christians on earth? And DNA should be possible to get, there are some nails with whose he's been supposedly been pierced, that thing which I have no idea what's called in English where the exact image of his face is imprinted since 2000 years, and probably some few other things. It's not like we need his whole body.

Mohammet could be next for cloning, just for the shits and giggles.

One day even dinosaurs will probably be brought back, you pessimists just think it's impossible cause we can't do it NOW.

DNA extracting is primitive

It's really fucking hard to expect DNA to survive over thousands of years

[EK !EKFQOBUFnQ No.4024691]

>>4024682
well yeah, but the further in time we go, the less likely it becomes as fossils have more and more time to degrade, unless some of the ones we already have well preseved are enough, like the mamoth guy was talking about, so maybe if we already have some good well preserved dinosaurs as well

[Anonymous No.4024694]

not gonna happen, nothing preserved.

The pharoahs were very well preserved though, so more likely them 30+ years from now

>>4024700
nah im not an attention whore or anything, i just know that as soon as things die dna starts to decay, and decays far faster than a lot of other bodily tissues, i mean bones and teeth stay the longest, but just from bones i dont think you can really extract the dna and clone an organism

I wonder if it will kick up any ethical issues. "we can't play god" etc. Maximum trolling if they want to reintroduce the clones to the wilderness.

Of course any action/moral panic/whatever will only happen *after* there is a successful clone, because that will be what is newsworthy and starts the whole thing. Why can we not into foresight?

Because average people are more interested in their TV serials than science, it's fine to keep them in the dark. Most people doesn't deserve to know what's going on around them - they can find out on their own. Their worthless selves aren't really fit to influence greater minds with their oh-so-useful 'moral high ground' etc.

Do those non-extinct animals have, say DNA? Maybe even have individuals of the species die on occasion? Perhaps some of them even live in cold climates?

I think a lot of it is technological right now. In about 10 years we should start noticing huge improvements in this field as long as it gets the proper funding. It can be done, just not that well. Needs some fine tuning if you get what i'm saying.

Long story short we need to sequence and synthesize the DNA, then implant it into an egg and finally put it in a suitable parent.

The problem is actually getting the DNA, most (if not all) of the tissue that would contain that is gone.

As per wikipedia:
"The successful extraction of ancient DNA from dinosaur fossils has been reported on two separate occasions, but, upon further inspection and peer review, neither of these reports could be confirmed."

Also, the longer we take to find it / develop methods of extraction, the more time it has to decay (although IMO another 100 years on what is already done isnt much).

And thats where we stand. I wonder if we will ever get to ride dinosaurs like in futurama..

To get this back on track and avoid a circlejerk the Western black rhino has today been declared extinct

Because of poachers who think the horns have magical properties, if I was in charge there I'd humanely remove the horns under a tranq so there'd be nothing for them to poach.

It does not matter that we are 'tripfags'. You should not be making fun of, or even drawing attention to, someones serious mental condition.

[Anonymous No.4025375]

>>4024705
but DNA doesn't always degrade...we've just recently sequenced the neanderthal genome, mammoths shouldn't be that hard. and in a few decades i wouldn't be surprised if it would be possible to backtrace from an existing organism to a mammoth, if you knew enough about the phenotype & selection pressures.

obviously it wouldn't be entirely valid, but would be cool.

[Harriet !x6oGOnISPY No.4025399]

>>4025375
You can not 'backtrace'.
It does not work like that.
Even though the ancestor of living things alive today was a mammoth at some point, some of the information is lost.

>wouldn't be entirely valid

i want my fucking mammoth. it's totally possible to create something that appears entirely like one today, through a lot of trial and error GM. obviously it wouldn't be of the same species, but it's close enough.

i'm pretty sure you could develop an algorithm to attempt a backtrace though. retained mutations in a species aren't random, and if you knew enough about its environment & selection pressures you could determine several likely genomes.
