While examining the history of our planet and
actively exploring our present environment, science journalist Michael Tennesen
describes what life on earth could look like after the next mass extinction.
A growing number of scientists agree we are headed
toward a mass extinction, perhaps in as little as three hundred years. There have already been five 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, returning 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?
Tennesen delves into the history of the planet and
travels to rain forests, canyons, craters, and caves all over the world to
explore the potential winners and losers of the next era of evolution. His
predictions, based on reports and interviews with top scientists, have vital
implications for life on earth today. Download and start listening now!
