What looks to be a good two part series, Origins will tell the theories and concepts of the origin of life here on terra firma.
----------------
Airing on PBS tomorrow and Wednesday, Origins revisits Earth during its unpromising first billion years and returns, even earlier, for the event that began it all: the big bang.
Origins explores how, against heavy odds, life on Earth began (possibly crash landing here from outer space). And it investigates whether today life exists anywhere else (maybe on one of the more than 100 newly discovered planets that lie beyond our solar system).
The show poses ancient, maybe obvious questions. But hardly idle ones, says Tyson, a leading astrophysicist and the director of New York's Hayden Planetarium at the American Museum of Natural History.
"Only when you know how something is born can you truly understand what has happened to it since then," he points out during a recent interview -- not to mention its prospects for the future.
A subtitle for Origins, says Tyson, could well have been The Search for Ourselves in the Cosmos. And -- flash! -- there is new hope for easing our identity crisis, thanks to a growing collaboration across scientific disciplines.
Among the many scientists he consults in telling the story of Earth are some whose careers are devoted to hybrid specialities "that I hadn't even dreamed of," Tyson says with evident amazement.
Example: biogeology.
"Historically, biologists accept that life thrives here on Earth's surface. But once we started finding life thriving elsewhere" -- like the hardy microbes recovered from rocks kilometres underground -- "it was clear that these life forms owed their existence to peculiarities in the geology of the earth."
Tyson views the collaborative process that yields a cross-cultural field like biogeology as a sort of intellectual liberation. And he points out that, oddly enough, it's a throwback to three or four centuries ago, when scientists (or "natural philosophers") remained generalists.
With increased specialization, says Tyson, came a range of different priorities and different sets of questions: Astrophysicists asked, "How did the universe get here?" Biologists asked, "How did life begin?" Geologists asked, "How did Earth begin?" Physicists asked, "What is the origin of the elements?"

I'll be watching, should be good substance for forum discussion...
