Will New Diseases Make an appearance?
If we bring back animals, will new diseases make an appearance?
New diseases can emerge, but it's not fully 100%
Name a movie that was mentioned during this presentation that portrays human greed for profit.
Avatar: The Way of Water, Jurassic World: Fallen Kingdom, King Kong, Rampage, and Jurassic World: Dominion.
What happened to the first animal brought back from extinction (Pyrenean Ibex)?
It died within minutes of birth due to lung malformations.
What is cloning?
When you take preserved DNA from an extinct species and place it in a related living animals egg cell
What is the potential problem with bringing back extinct animals?
They could become invasive to organisms already living in the ecosystem.
Why might reintroduced species carry diseases not currently present in an ecosystem?
Because they could be carriers of diseases from different environments.
Why is it impossible to predict chaos?
Small variables that are seemingly random events can change the entire course of the future.
What is one ethical concern related to the quality of life for revived extinct animals?
There is a high risk of birth defects, which can cause suffering.
What is used in gene editing?
CRISPR
What might happen if a reintroduced species competes with current species for resources?
It could disrupt food chains or even lead to the extinction of current species.
How might extinct species be more vulnerable than native species in terms of disease resistance?
They may not have the same level of immunity to local pathogens that native species have evolved to resist.
Who first introduced chaos, and in what year?
Ed Lorenz in the 1960s.
How might the ability to bring back extinct animals affect its efforts?
It may weaken efforts to protect biodiversity and habitats because people might think it's okay to let species go extinct if they can be revived later.
How does backbreeding work?
It is when you breed animals with the same traits as the extinct one.
Why might a reintroduced species become invasive in its former habitat?
Because the environment may have changed, or other species may now occupy its old role.
How does the example of the woolly mammoth support the argument against reintroducing extinct species?
Attempting to bring back the woolly mammoth was linked to the reintroduction of EEHV, a fatal disease in young Asian elephants.
What is sensitive dependence on initial conditions?
The accuracy of the predicted system is determined by the accuracy of the numbers plugged in, down to all the decimals.
Why is it irresponsible to bring back extinct animals without restoring their natural habitats?
Because many went extinct due to habitat destruction, and without those habitats, the animals may be forced into captivity or become extinct again.
How do scientists make hybrids?
They combine the DNA of extinct species with that of their modern relatives to create hybrids.
What are the two opposing scientific views about de-extinction mentioned in the text?
Some scientists believe de-extinction could help restore balance in ecosystems, while others warn it could cause harm without careful management.
What are some possible ecological consequences if a reintroduced species brings a new disease into an ecosystem?
It could disrupt the balance of the ecosystem by harming native species, reducing biodiversity, or causing the spread of epidemics that native animals are not equipped to handle.
Which two scientists did the Chaos Theory go against?
Pierre-Simon Laplace and Isaac Newton
How do the ethical issues mentioned challenge the idea that de-extinction is a beneficial scientific advancement?
They show that de-extinction could cause animal suffering and reduce the urgency to conserve modern species
How can De-Extinction come to be? What needs to occur for it to be possible?
DNA Collection of the extinct species
What factors should scientists consider before reintroducing an extinct species into an ecosystem?
They should study how the ecosystem has changed, whether other species now fill the extinct species’ role, potential impacts on food chains, competition for resources, and risks of causing harm to current species.
