De-extinction by Naiara Sanchez Bermudez https://padlet.com/naiarasanchez1/xcsg6i8vgsm8w9dh en-us 2023-01-19 15:07:19 UTC 2023-03-16 15:15:18 UTC hello@padlet.com Somos documentales - Des-Extinción naiarasanchez1 https://padlet.com/naiarasanchez1/xcsg6i8vgsm8w9dh/wish/2449947271 Main idea:
Scientifics trying to think about reviving mamuts
Arguments/facts:
- Talks about the video
- Said that the bones of many creatures are in a good state (dinosaurs, mamuts)
-They could probably agree that de-extinction could happen
Dialogue:
-I think Jurassic park doesn't match very well this topic
Summary:
It talks about jurassic park, it could be the first film talking about de-extinction. Scientifics could prove that de-extinction could happen in real life, because some bones of creatures that are extinct are in a good state, so we could probably bring them to live

The most exact replicas of an extinct animal are from a preserved cell from that exact animal.
Arguments/facts:
- Thomas Gilbert tries to revive the Christmas rat

- The only thing selective breeding has been able to do is to create an animal hybrid.

- Animals extinct a long time ago aren't able to be de-extinct

Dialogue:
- Did Thomas gilbert succeed in the experiment?
- If they had preserved the cells of mammoths they would be revived?
-Do the hybrids from the experiments survive?
Summary:
Thomas Gilbert, a researcher and professor at the University of Copenhagen, researched the practicality of de-extinction by attempting to revive the Christmas Island rat, which DNA is excellently preserved.  Also, the Christmas Island rat was related to the standard brown Norway rat. This rat is important because studies of living species have shown that alterations in their DNA can have significant effects, and be close to reviving an extinct creature. Unfortunately, by genetic engineering and selective breeding experiments, they are only able to create a hybrid animal, rather than a resurrected animal. The closest you can get to an exact genetic replica of an extinct animal is a clone created from a preserved cell from the species you want de-extinct. For that reason, many extinct animals that are extinct for a long time ago are not possible to de-extinct.

- Animal has to be able to breed naturally
- Extinct animals lumber through their natural habitat.
-De-extinction is in a slow process of development
- The first animal de-extinted was in 2003 and scientists

-Depending on the species, to de extinct scientist  use  ‘back-breeding
Dialogue
we believe that de-extincion is fascinating but we are scared for the animals that can be revived for later die
Summary
De-extinction aims to create populations of healthy, genetically vibrant animals that can be released into the wild and that are able to breed naturally and contribute positively to the environment.
Every day, between 30 to 150 species disappear and we have dicovered that extinction rate is 1,000 times higher than before human started to evole. Now a days our world suffers a massive extinction rate, and de-extinction is a way to undo all the extinction we humans have caused.
The first de-extincion was in 2003  scientists resurrected the Pyrenean ibex.
It died a few minutes after she was born, so the Pyrenean ibex was the first animal to be brought back from extinction, and the first to go extinct twice.
Thanks to technological advances and gene-editing technology scientists will soon be able to bring back species from extinction.

Dialogue:
-what are the  balancing benefits of bringing the animals back?
Summary:
They have gone extinct because we humans have exploited them.

When a specie goes extinct if it had a disease impacted, it would disappear, but if we den bring back that specie the disease would come back and cause health problems to us and other animals.

If we bring back a specie of animal we can maybe not have the habitat they have to live in because environments have changed and that could have an impact on them.

Jenna Small ( a reviewer) said that if we bring now five species of animals that don't exist more than 42 species of animals could be affected by them and cause extinction for those 42 species, so if we bring back a specie we can also lose species.

If we bring back historical animals like the Mammoth, they would be in captivity and stay in a zoo or a closed safe place because we wouldn't want them to die or something happens to them. That would cause the animal many more problems like mental ones.

Many projects have been created to de-extinct animals

Argument/Facts
-  The quagga was a type of zebra that was extinct many years ago.
- It will be one of the first to be de-extinct
- 2 really prodegies of science, Heinz and Lutz are going to try to de-extinct Auroch Phenotype

Dialog
- When will the project to revive the quagga start?
- how does selective cossbreading work?
- Did the sheep survive?
Summary
The quagga, a South African zebra with stripes on only the front half of its body, became extinct in the 12 August 1883, when the last specimen died in the Amsterdam Zoo. Current advances are making de-extinction possible thanks to science. And the quagga is one of the first animals scientists want to successfully de-extinct. In 1921, 2 German zoologists Heinz and Lutz Heck launched a program to restore the Auroch Phenotype, the wild ancestor of Bos Taurus. They used selective crossbreeding to obtain new varieties of domestic animals. Selective crossbreeding is able thanks to cloning, they used the same complex cloning that when they clone the sheep Dolly in 1996, it was a great advancement because she was the first mammal to be cloned.

Summary:
Many animals have gone extinct before we had all these advanced technologies and bringing back some species would help us gain more awareness of how our world works and information that today we don't know.

It would get us more experience because the only tact we have with extinct animals is with videos, photos etc..

It would help us bring genetics back to plant-animal lines and improve animal health.

It would help the environment because some of them suffer because there are not he animals that have to be there so we would restore the environment

Bringing back extinct species could lead to biodiversity loss rather than gain.

Arguments and facts
- De-extinction harms close relatives of creatures

-The loss of animals endangers their ecosystem

Dialogue
- How can an ecosystem die without its different species?
- It will be better to protect endangered species, rather than revive already extinct ones.

Summary
The scientist Professor Hugh Possingham said that the research suggested that conservation budgets to cover the costs of de-extinction could endanger already existing species. He clearly states that the many experiments performed on the already existing species to bring back the extinct ones are extremely dangerous because we lose many living species and de-extinction is still in development and we could lose many animal lives. The loss of animals endangers their ecosystem and many other animals will die. Everything in their environment will not survive without the dead species. 

And the scientist Dr Joseph Bennett found out that reintroducing some extinct species to their old habitats might improve biodiversity, but the money spent for reviving 11 extinct species could be used for the conservation of 33 endangered species.

De-extinction is still in progress and we can't fully revive creatures.

Arguments and facts
- There are many processes to revive an extinct creature
- The creature's DNA has to be well conserved

Dialogue
- we believe that we should take care of the animals that aren't extinct yet, rather than continue to revive extinct creatures.

Summary
The exact definition of de-extinction is a set of techniques that allows an extinct species to breed again, but unfortunately, de-extinction is not capable of reviving a creature to its true state, but rather making a hybrid between the extinct animal and his closest relative. There are many processes to de-extinct a creature, like selective breeding or genetically modifying creatures, we can also de-extinct by simple cloning, but unfortunately, it can only happen when the extinct animal has been extinct recently.

Is to adapt an ancient ecosystem to a modern one with environmental changes such as global warming.
Arguments and facts
-4,000 years ago Canada and Russia consisted of an ice-based ecosystem but now they are melting if this continues to melt it will release greenhouse gases which will have serious consequences like burning all forests.
-Mamooths can help with fires in forests because they eat dead grass and that would leave new grass to be formed and not cause fires

Dialogue
-Does any other animal can help with also cooling the environment?

Summary
Scientific American states that reviving species such as woolly mammoths from surviving DNA is a terrible ethical decision. Reanimation is about manipulating the best ancient DNA. If we are able to master reanimation, we could save millions of lives. Aside from bringing back extinct species, reanimation could help living ones by restoring them to their former glory. The Tasmanian devil is so inbred at this point that most species members can exchange tumor cells without rejection. A rare transmissible cancer spread via facial wounds drives the species toward extinction.

We can't revive creatures that have been extinct a long time ago. And with de-extinction, we are able to genetically modify creatures to eliminate their flaws, so they will not get extinct again and they can beneficiate their environments.

Arguments and Facts
- Only species with really old DNA are the only ones impossible to de-extinct

-Malfunctions can be cured in the process of de-extinction and like this animals can't get extinct twice

-Humans killed off a lot of species over the last 10,000 years.

Dialogue
- Why we can't revive creatures that have been extinct a long time ago?
-How do they eliminate their flaws?
- How can animals beneficiate their environments?

Summary
There are many reasons to bring back extinct animals. Only species with a really old DNA, such as dinosaurs, are the only ones scientist consider extinct.
Many examinations of extinct species can tell us why did they get extinct. Technology for de-extinction will also be used for endangered species. A species with a genetic malfunction can be cured with an adjustment in its DNA during cloning. That gene can be used to stop diseases caused by wild animals.
Many animals were important for their habitat. For example, the passenger pigeon was important for a forest located in Mississippi.
Humans killed off a lot of species over the last 10,000 years. And many of their habitats became horrible death lands.

- our favorite is the Dodo
- we would be terrified if the  was de-extinct

Summary
1-Caspian Tiger: bring them back because of  reintroducing their identical Siberian tigers to their old habitats where scientists expect them to adapt
2-Aurochs: bring them back by selective breeding because of their DNA.
3-Carolina Parakeet: the genes that made them are still in Mexico and the Caribbean 
4-Cuban Macaw: they have similarities in appearance with bred birds but they are a little bit bigger.
5-Dodo: in 2007 scientists found a dodo skeleton perfectly preserved and they made lots of DNA samples with it
6-Wolly Mammoth: they can cool the environment, scientists say we are the blame for their extinction.
7-Labrador Duck: they don't taste good so people won't eat them,
8-Wolly Rhinoceros: they have a very well-suited body for the cold.
9-Heath Hen: They are delicious and people ate them for thanksgiving so scientists say they are another candidate.
10-Ivory-billed Woodpecker: they lived in virgin forests and there hasn't been one specie since 1940
11-Imperial woodpeckers: they are listed as possibly extinct, their habitat was destroyed by humans, and scientists want to bring them back to make up for what humans did.
12-Moa: extinct because of people hunting them, their genes can be possibly  still in South America
13-Elephant bird: only found in Madagascar but scientists think people made them extinct too so they want to make up for that.
14-Pyrenean Ibex: Scientists tried to clone one but did a few minutes after being born.
15-Quagga: last one was shot in 1870, quagga project started  in 1987 to bring them back
16-Freshwater Dolphin: thought that they are extinct but found one in the river a few years ago they want to bring him back to make them not extinct.
17-Tasmanian Tiger: Tasmanian devils maybe carry some of their DNA.
18-Irish Elk: Red deer or fallow deer maybe have similar genes, they were one of the largest deers to be on earth.
19-Caribean Monk seal: closely related to Hawaiian monk seals, hunted for extinction because for use of oil.
20-Huia: there is little known about them, so they want to bring them back to know more about them.
21-Moho: died because of habitat loss, some birds like waxwings may carry some similar genetics
22-Steller's Sea cow: they were hunted to extinction because they were one of the two species of sea cows, scientists may bring them back by Dugongs because they carry a little bit of their DNA.
23-Passenger Pigeons: haunted for food for slaves, the last one died in 1914.
24-Gastric-brooding Frog: extinct in 1983, they swallowed eggs and hatched them .scientist tried to bring them back in 2013.
25-Great Auk: died because of a combination of climate change during a little ice age that brought the predatory polar bear to the earth.

The possibility of bringing back species has been raised because of advanced technologies in selective breeding, genetics, and reproductive cloning.
In 2009 scientists nearly brought back a Pyrenean Ibex with preserved tissues, but died a few minutes later after being born because of a lung being deformed.
Genetic technologies have advanced and higher the possibility of bringing back poorly preserved species.
CRISPR is an enzyme system that edits DNA in certain microorganisms.
SCNT transfers the nucleus of a somatic cell o an animal one to be cloned into the cytoplasm of a donor egg. The egg cell is simulated into cell division which leads to the formation of the embryo which is later transferred to the embryo of a female which is similar to the one that is going to be cloned.

Everything in their environment will not survive without the dead species. 


And the environment of the extinct animals would have changed and reintroducing them back it could be catastrophic]]> 2023-03-16 15:12:14 UTC https://padlet.com/naiarasanchez1/xcsg6i8vgsm8w9dh/wish/2519570731
