them.They are unlikely to survive in the natural environment,but,if they do manage to survive,they will affect their environment in unpredictable ways,presenting a new threat to the ecological system.If the animals born through de-extinction are stuck in zoos and museums instead,what good is ...
【题目】E"De-extinction", the idea that extinct(绝种的)animals can be brought back through cloning or genetic(基因的)engineering , has attracted theinterest of a small group of Scientists . T he topic had made the cover of National Geographic Magazine. Supporters say they are doing itfor ...
Yet, there is some protest that de-extinction itself can also be interpreted as playing God. Those in opposition argue that since the resurrected animals can never be 100% identical to the extinct original, de-extinction does not truly reverse the ecological damage caused by humans.Still, others...
Thanks to a process called de-extinction, hope is not lost for extinct animals. Here is a list of 25 extinct animals that scientists want to de-extinct:
"So we're always focused on, 'How does de extinction play this important role in the broader scheme?'" he said. "...It's really trying to restore species we've lost while trying to keep species from going extinct."
This idea dovetails neatly with the image of Noah’s animals marching “two by two” into the Ark. But the science of “minimum viable populations” tells us a different story. No inbreeding, please The global gold standard used to assess the extinction risk of any species is the Internation...
The same techniques being developed to help resurrect extinct species can also be used to help save living species on the brink of extinction. So how does de-extinction work, what are its limits, and do we really need to bring back long-dead animals?
I think we choose the charismatic animals because it’s exciting. How do we excite other people about an insect? Well, there’s theXerces blue butterfly[whichhuman activity drove to extinctionin the 1940s in the San Francisco Bay] that’s beautiful and charismatic. Should we think about tha...
Using a method called CRISPR, scientists can change the genes of living animals, but this process is too slow for large-scale testing. Per Dr. Church, instead of waiting for the nearly two-year gestation period in elephants, scientists may use stem cells to determine wheth...
