Study Provides Compelling Evidence of Single Impact Extinction Theory

Posted by ScuttleMonkey on from the scientists-all-looking-for-someone-named-ele dept.

ectotherm writes to tell us that a new study at the University of Missouri-Columbia claims to provide compelling evidence that a single meteor impact was the cause of animal extinction 65 million years ago. From the article: "MacLeod and his co-investigators studied sediment recovered from the Demerara Rise in the Atlantic Ocean northeast of South America, about 4,500 km (approximately 2,800 miles) from the impact site on the Yucatan Peninsula. Sites closer to and farther from the impact site have been studied, but few intermediary sites such as this have been explored."

    >> equal amount of evidence for other possibilities regarding the origin of life
    The theory of evolution is not a theory regarding the origin of life.

    >> The Monkeyists might like to know
    I presume you're trying to imply that people are thought to be descended from monkeys. This is not what evolution states.

    >> there hase to be NO CHANGE in the ratio of carbon 14 to carbon 12
    This is true. In fact, the ratio has not been constant. A quick look at en.wikipedia.org/wiki/Carbon_dating shows that scientists are aware of this. (who would have thunk it?)
    So, is the ratio constant historically? No. Does that make carbon dating useless? No.

    >> I do expect at least 5 posts arguing against what I say
    That'd be because what you say is factually incorrect and misleading.
