‘The Models Are Too Conservative’: A Paleontologist on Climate Change Today "“Probably calling Trump a war criminal was a bit much.”" (by David Wallace-Wells) http://nymag.com/daily/intelligencer/2017/07/what-mass-extinctions-teach-us-about-climate-change-today.html?utm_source=fb&utm_medium=s3&utm_campaign=sharebutton-t

What people are not really understanding is that genes can jump from species to species very easily. My 19th book, actually, is called Lamarck’s Revenge, the story of epigenetics. My unique new take is epigenetics in the history of life. The reason we get these outpourings of new body types in the aftermath of mass extinctions is not Darwinian — it’s too slow. Epigenetics occur when there is environmental change. It works for microbes all the way up.

People always think the intensity of a mass extinction should be related to the extinction — what percentage of creatures were extinct. Increasingly, we’re thinking that’s a metric, but a more important metric that tells you something about the nature of the devastation is how different is the fauna that comes afterward.

But one possibility is we are stuck here. And if you look at the Fermi paradox, it could be that lots of organisms are stuck on their planets because the galaxy has not been colonized. I’ve been doing these web talks with NASA people. One of the really interesting concepts around the Fermi paradox is the Great Filter — that civilizations rise, but there’s an environmental filter that causes them to die off again, and disappear fairly quickly. If you look at planet Earth, the filtering we’ve had has been in these mass extinctions.
