渡渡鸟复活计划：现实版“侏罗纪公园”要来了？
In English，“as dead as a dodo” means someone or something is totally，unquestionably dead. But the dodo，a tubby (矮胖的) bird that has been extinct (灭绝的) for hundreds of years，may not be dead anymore!
US company Colossal Biosciences said it would try to bring the dodo back to life. The bird used to live on the island of Mauritius (毛里求斯) in the Indian Ocean until the 17th century.
“[The place] to bring back the dodo into the wild would be Mauritius，” Ben Lamm，the co-founder of the company told The Guardian. Bringing back dodos into the ecosystem (生态系统) of the island，instead of being a newcomer to somewhere else，is thought to bring benefits to the plants and animals that already live there.
The company has found the genetic code (基因序列) of the extinct animals from their dead bodies. It will change the DNA of currently living animals to make them close to the animal of the past. The Nicobar pigeon (尼柯巴鸠) will be used as the genetic base for the dodo，according to MIT Technology Review.
However，some people don’t like the idea. With a third of all bird species in decline (减少)，protecting today’s species is needed more than focusing on animals of the past，said BBC Science Focus.
How to bring back dodos?
Scientists studied the DNA of the dodo to understand its structure (结构). This work finished in March 2022.
Scientists then compared the dodo’s DNA with that of other birds to find its closest relative (亲缘动物) – the Nicobar pigeon.
Scientists will take DNA from a skin cell (皮肤细胞) of the Nicobar pigeon and combine it with the dodo’s. This is the gene-editing (基因编辑) process.
Then they will put the DNA into an egg cell and develop the cell into an embryo (胚胎).
