C. By cloning. D. By feeding other animals. 相关知识点: 试题来源: 解析 C. By cloning. 让灭绝动物重现,目前最有可能的方法是克隆。虽然克隆技术仍面临技术和伦理挑战,但它是目前唯一可行的方案。其他选项,如保护环境、寻找其他星球或喂养其他动物,都无法直接让灭绝动物回归。反馈 收藏 ...
Can We Bring Back Dinosaurs (Just Like In Jurassic Park)? What Is De-extinction? The International Union for the Conservation of Nature (IUCN)guidelinesdefine de-extinction as the generation of proxies of extinct species that are functionally equivalent to the original extinct species, but are not...
and by choosing to bring back animals that are genetically unique – like the gastric-brooding frog or the Tasmanian tiger (a stripy, pouched, dog-like marsupial also known as the thylacine) – we could replace not just twigs, but entire ...
C“De-extinction", the idea that extinct(绝种的) animals can be brought back through cloning orgenetic(基因的) engineering, has attracted the interest of a small group of scientists. The topic hasmade the cover of National Geographic Magazine. Supporters say they are doing it for moral ...
We live in Beijing, and the environment in Beijing is directly related to our existence! But Beijing's environment is very bad now, such as: poor air quality, less plants, sewage, garbage dump more problems etc. These people are not enough to bring a devastating disaster, such as: dust ...
for moral reasons and because we"miss"the extinct animals.They blame human exploitation (such as trapping,hunting,habitat destruction) of the extinct animals,but their plans,though they sound exciting,are exploitation in another form.Considering the imperfect science of cloning,de-extinction would caus...
Can We Bring Back Dinosaurs (Just Like In Jurassic Park)? Can We Create Life From DNA? The cell of an adult animal has all the DNA necessary to create other cells, and thus make another animal altogether. Scientists have often used a technique calledcloningto make copies of cells,genes, ...
Shapiro's new book examines the capacity of science to bring back extinct animals.UC Santa Cruz Humans have long tinkered with life—what’s the most fascinating example? Domestication, from dogs and cats to farm animals to the diversity of crop plants that we rely on for food, to...
When these animals become adults, they will have babies. And these baby animals will have the DNA of the extinct animals. Scientists believe it is possible to bring back passenger pigeons and many other animals. However, not everyone thinks this is a good idea. Stuart Primm is the world'...
told AFP.There are three pathways to bringing back extinct animals: back-breeding related species to achieve lost traits; cloning, which was used to createDolly the sheepin 1996; and finally genetic editing, which Gilbert and colleagues looked at.1997 photo of Dolly the sheep, the world's fir...
