I strongly believe in the popular theroy that an asteriod wiped out the dinsours It is widely agreed that such an object -- 10 kilometers across -- struck just off the coast of the Yucatan peninsula 65 million years ago. For months, scientists conclude, dense clouds of dust blocked the sun's rays, darkening the Earth and nearly freezing it to deadly levels for most plants and, in turn, many animals. Then when the dust finally settled, greenhouse gases created by the impact caused temperatures to skyrocket above pre-impact levels. This is a widely belived theroy that most people can agree on including myself.

Hello, First I would like to thank my debator for inviting me too this debate. Without further ab-due I will dive into this debate. When a scientific principle is common knowledge even in grammar schools, you know it's long since crossed the line from theory to established fact. That's the case with dinosaur extinction. Some 65 million years ago — as we've all come to know — an asteroid struck the Earth, sending up a cloud that blocked the sun and cooled the planet. That, in turn, wiped out the dinosaurs and made way for the rise of the mammals. The suddenness with which so many species vanished after the 65-million-year mark always suggested a single cataclysmic event, and the 1978 discovery of a 112-mi., 65-million-year-old crater off the Yucat�n peninsula near the town of Chicxulub seemed to seal the deal.

Now, however, a new study in the Journal of the Geological Society throws all of that into question. The asteroid impact and the dinosaur extinction, argue the authors, may not have been simultaneous, but rather may have occurred 300,000 years apart. That's an eye-blink in geological time, but it's a relevant eye-blink all the same, one that occurred at just the right moment in ancient history to have sent the extinction theory entirely awry.

I'm not saying that all of this happened within a day, nor a year. I do agree that this kind of thing takes time. First, after this cataclysmic event, all sorts of dust, debris, and what have you are all either stuck in the atmosphere or falling from the sky. The dinosaurs that didn't get wasted by this initial impact now are at great risk of getting struck by falling objects. The dinosaurs who survive that are now slowly suffocating, as are the plants. (not a pretty picture but it's science!) as everything slowly begins to die out you first have the plants, then the herbivores, then the carnivores until you only have the small, previously insignificant, mammals who decided to stock up food and grab what they can to survive. So again, yes, these things take time.
