科学家们说，他们已经破解了海蟾蜍的 DNA 蓝图，该物种对部分动植物栖息地造成了破坏，而这一发现让人们重新燃起了控制这一事态的希望。
The cane toad originally came from South America and was introduced to Australia in 1935 with the hope that they would eat the beetles which were devouring sugar cane. But they ended up eating everything except the beetles. And they've been spreading through Australia ever since, poisoning native wildlife as they go.
Snakes, lizards and even crocodiles can die if they ingest the amphibian's deadly toxin. Now the possibility of a genetics-led solution is at hand. An international team of scientists has succeeded in unlocking more than 90% of the toad's genome – its genetic material. To get this information, the teams used advanced computers to sequence 360 billion DNA pairs, meaning they've worked out the exact order of the four bases in a strand of DNA.
The researchers said the discovery would offer biological clues about the animal's evolution. The scientists have also discovered three new viruses within the toad's DNA, which could be used to control pests. But in a country which has a long history of introducing species with disastrous consequences, scientists will be cautious with the way they use this new information.
