That is, according to new research conducted at UC Berkeley and reported on at the San Francisco Chronicle.
Their research is based on fossil records spanning more than 500
million years, and they conclude that mass extinction on the earth
occurs in 62 million year cycles. There are some fun theories:
Or perhaps there's some kind of "natural timetable" deep inside the Earth
that triggers cycles of massive volcanism, Rohde has thought. There's even a
bit of evidence: A huge slab of volcanic basalt known as the Deccan Traps in
India has been dated to 65 million years ago -- just when the dinosaurs died,
he noted. And the similar basaltic Siberian Traps were formed by volcanism
about 250 million years ago, at the end of the Permian period, when the
greatest of all mass extinctions drove more than 70 percent of all the world's
marine life to death, Rohde said.
A lot of room for speculation. I read that aging and natural
death look to be the result of some internal body clock saying 'now
it's time to die' rather than organs declining in quality, so I guess
you could draw comparisons on how everything is connected, or
