Post 138749 by Blasdelb deleted for the following reason: Sorry for the delay on this, but I've been working through the links and trying to see if the critical material is actually available for people to refer to, and this seems to be the problem: at this point it appears that only the few people who have access to the actual paywalled study can discuss the figures and methodology of some of the most surprising claims, while others sort of stand by or express doubt or support of the Slate interpretation. Blasdelb, it's a fascinating topic, and maybe you can rework this and repost in a way that will work a little better. Thanks. -- taz
