The extinction rate is now 1000 times normal, says Duke University.

Not to worry, say Stanford, Berkeley, Princeton, and the University of Florida (and what would they know, those ‘gators with their beady dinosaur eyes), it’s only 114 times normal using “conservative assumptions”.

And according to a surprisingly edgy book review in my favorite special interest publication Civil Engineering (because what could be more special than my own interest), there is a new book out:

You probably don’t subscribe to Civil Engineering, so here is the Amazon description:

A growing number of scientists agree we are headed toward a mass extinction, perhaps in as little as 300 years. Already there have been five mass extinctions in the last 600 million years, including the Cretaceous Extinction, during which an asteroid knocked out the dinosaurs. Though these events were initially destructive, they were also prime movers of evolutionary change in nature. And we can see some of the warning signs of another extinction event coming, as our oceans lose both fish and oxygen. In The Next Species, Michael Tennesen questions what life might be like after it happens.

Tennesen discusses the future of nature and whether humans will make it through the bottleneck of extinction. Without man, could the seas regenerate to what they were before fishing vessels? Could life suddenly get very big as it did before the arrival of humans? And what if man survives the coming catastrophes, but in reduced populations? Would those groups be isolated enough to become distinct species? Could the conquest of Mars lead to another form of human? Could we upload our minds into a computer and live in a virtual reality? Or could genetic engineering create a more intelligent and long-lived creature that might shun the rest of us? And how would we recognize the next humans? Are they with us now?
