By Scott D. Pierce Deseret News BEVERLY HILLS, Calif. -- Who doesn't love a show about prehistoric monsters chasing people around the modern world? That's an oversimplification of the BBC America series "Primeval," but it does help explain the series' multigenerational appeal.

Asteroids that strike Earth have cosmic origins, but clues to the size of ancient impactors now have come from a decidedly Earth-bound source: the chemistry of ancient seawater.

Whenever the world's tropical seas warm several degrees, Earth has experienced mass extinctions over millions of years, according to a first-of-its-kind statistical study of fossil records.

New scientific findings suggest that a large comet may have exploded over North America 12,900 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of much of the planet and the extinction of large mammals.

The sudden appearance of large animal fossils more than 500 million years ago – a problem that perplexed even Charles Darwin and is commonly known as “Darwin’s Dilemma” – may be due to a huge increase of oxygen in the world’s oceans.

A distant supernova that exploded 41,000 years ago may have led to the extinction of the mammoth. This theory joins the list of possible culprits responsible for the demise of mammoths, which last roamed North America roughly 13,000 years ago. Scientists have long eyed climate change, disease, or intensive hunting by humans as likely suspects.

An oxygen-free ocean from bottom to surface is probably the worst scenario that marine higher life can experience. Are processes and feedbacks linking the atmosphere to the deep ocean capable to cause a rapid change from an oxygen-rich to an oxygen-free deep ocean? And what are the consequences for the global carbon cycle that ultimately drive marine and terrestrial ecosystems and climate variation?
