其次這個視頻的作者使用的原話應該是「來自美國、英國等多國的國際科學家團隊於3月3日發表在《科學報告》的研究指出，珊瑚表現出了與大約6600萬年前的生物大滅絕事件發生時一樣的特徵，這表明珊瑚正在為一場重大滅絕事件做準備」。咋一看國際科學家團隊，又是發表了論文，說珊瑚正在為一場大滅絕事件做準備，這裡就產生了兩個問題，「一樣的特徵」是指的什麼特徵？這個「大滅絕事件」指的是針對珊瑚而言還是全部生物而言？為了解決這兩個問題，我們需要查看一下原文。由於不知道DOI號，只能看到題目等信息，因此我首先在web of science搜索了題目「Evolutionary Traits that Enable Scleractinian Corals to Survive Mass Extinction Events」結果如圖5所示，並沒有任何結果。

考慮到可能存在一些特殊情況，於是我又查看了scientific reports的最近論文，一看嚇一跳，如圖6所示2020年的文章居然有300多篇了，果然是涉獵廣泛的一個多學科期刊~~~可以看到上面並沒有三月份的文章，最上面兩個2020年12月的，從第三篇文章開始就成了2020年2月，想來是三月的文章還沒來得及傳到web of science，於是只能去官網尋找。

打開官網網站，直接搜索文章標題果然是有的，如圖7圖8所示

按照習慣粗讀論文，先看摘要後看結論，這裡解決了第一個問題，這個所謂的「特徵」指的是「We review this history and assess traits correlated with K-T mass extinction survival. Disaster-related 「survival」 traits that emerged from our analysis are: (1) deep water residing (&>100 m); (2) cosmopolitan distributions, (3) non-symbiotic, (4) solitary or small colonies and (5) bleaching-resistant.」感興趣大家可以自行翻譯，或者看我人工智障翻譯的味道「我們回顧此歷史並評估與K-T滅絕生存相關的性狀。從我們的分析中得出的與災害相關的「生存」特徵是：（1）駐留在深水中（&> 100 m）； （2）世界性分布；（3）非共生；（4）單獨或小的菌落；（5）耐漂白。」
然後摘要繼續說到We then compared these traits to the traits of modern Scleractinian corals, using to IUCN Red List data, and report that corals with these same survival traits have relatively stable populations, while those lacking them are presently decreasing in abundance and diversity. This shows corals exhibiting a similar dynamic survival response as seen at the last major extinction, the K-T. 我只是大致粗看了一下，認為核心觀點是他們通過與現存的珊瑚進行特徵對比，發現了具有這種特徵的珊瑚生存的還算OK，但是不具備這些特點的珊瑚則是表現出來數量與物種多樣性在下降的趨勢，然後提出了一個觀點：「這表明珊瑚表現出與最後一次大滅絕K-T相似的動態生存反應「也就引出了生物大滅絕的話題。
最終文章最後一段的總結如下作者認為，通過對上述兩個不同滅絕事件對比，發現了倖存珊瑚的相似性狀，「 imply that there is a basic mechanism which enables a coral to become a 「mass extinction survivor」 and which may be maintained for tens of millions of years. 」中間balabala不在贅述，然後又進行總結了說「珊瑚礁群落目前正在過渡到災難群落。」然後balabala對這個災難對珊瑚族群的影響以及後續的恢復表示了擔憂。最後「And unlike the Order Scleractinia, Primates do not possess analogous 「survival」 traits that enable some species to transcend major extinction boundaries, nor does Homo sapiens or any other Primate species, have a track record of mass extinction survival.」我認為這裡就很明確了，災難是珊瑚的災難，珊瑚表現出了與多年前生物大滅絕時相類似的特徵的族群容易存活，不具備這種特徵的珊瑚正在走向滅亡。PS在我個人的印象中，某地理課本上就有說澳洲大堡礁正在逐漸被破壞並且可能在xxxx年完全消失（對自己的記憶存疑）
「We suggest that the similarity in traits allowing coral survival exists through two very different extinction events (Table 2) imply that there is a basic mechanism which enables a coral to become a 「mass extinction survivor」 and which may be maintained for tens of millions of years. Recognizing this, we might predict a long-term change in coral assemblages to more solitary, non-symbiotic communities, similar to early Paleocene assemblages. In this scenario, already evidenced in some of the world』s largest coral reef systems34, the dominance of corals in contemporary coral reefs may be replaced by algae or other invertebrates』 dominance, due to the loss of competitive advantage in low nutrient exploitation and structure building. A community shift in this direction will damage their reef-building capacity and structural complexity that supports the highest biodiversity among all marine ecosystems. This study provides alarming evidence that reef communities are currently in the process of transitioning into disaster communities, akin to previous extinction events. Recovery of coral reef ecosystems from the K-T mass extinction was slow (2–10 My), as judged by the Paleocene re-establishment of algal symbiosis39. While the slow recovery time of coral reefs following a mass extinction is distressing, we also call attention that Primates (the Order that also includes humans) are also increasingly becoming threatened with extinction61. And unlike the Order Scleractinia, Primates do not possess analogous 「survival」 traits that enable some species to transcend major extinction boundaries, nor does Homo sapiens or any other Primate species, have a track record of mass extinction survival.」
