> But the researchers found that in 38 percent of the impacted colonies, the polyps had devised a survival strategy: shrinking their dimensions, partly abandoning their original skeleton, and gradually, over a period of several years, growing back and starting a new skeleton.
Is it that 38% use this method or they all try to use this method and only 38% are successful?
- dev_dull 7y agoAlso, who’s to say they “developed” that? That makes it sound like they’re dealing with something completely new (fits into man-made climate change narrative). Is it possible that through millions of years of evolution the earth had many such warming experiences and they developed this technique well before we arrived on the scene?
- sterkekoffie 7y agoIf you'd RTA you'd have answered your question. We've long had evidence for this type of recovery happening. The problem is that the evidence is from the Paleozoic fossil record. It's vanishingly unlikely that /no/ corals ever undertook this process in the past 300 million years but it's not typical behavior and it's extremely significant that it's been observed in modern corals. We know that catastrophic climate change has occurred in the past. Climate scientists are not proposing this is new on a geological time scale. But it's new to us and to most extant species. We don't all have these tricks up our sleeves.

There were several rapid ~10 C temperature changes at the end of the pleistocene period 10-15k years ago: https://wattsupwiththat.com/2012/06/19/the-intriguing-problem-of-the-younger-dryaswhat-does-it-mean-and-what-caused-it/ https://wattsupwiththat.com/2012/06/19/the-intriguing-proble...
