Very enlightening short talk by Willis Eschenbach at the recent Heartland Institute Climate Conference in Chicago. Your 15 minutes would be VERY well spent! climateconferences.heartland.org/iccc7/P.S. All thirteen 2012 Heartland lectures are included in this link. |

We don't even know how many species there are. So how can we know whether they are accelerating or not? As we become aware of more species and they are studied, it may be that some species found may [or not] be on the edge of extinction, so it would appear that there is an acceleration but overall it could be a deceleration, we just don't know for sure. More hype to gather funds.

What I found most interesting in Eschenbach's speech was the bit about the large quantity of "surplus to requirements" DNA that doesn't have any "apparent" use. He hypothesized it could be "switched on" when environmental conditions change so that the creature can cope with change without going extinct.
I think this is a very thought provoking idea! I wonder if any work has been done on it? If correct it could alter our ideas about evolution and the survival of the fittest.
