What do you think?

Question by Dami F’sho hates HOES: What do you think?
In the article “Sex, Drugs, Disasters, and the Extinction of the Dinosaurs,” Stephen Jay Gould puts forth three explanations that have been given for the demise of the dinosaurs: sex, drugs, and disaster.

Disaster: There is a site in the Yucatan where a large comet hit the earth approximately 65 million year ago. The hypothesis is that as a result of this comet hitting the earth there was the formation of a huge, worldwide dust cloud, which blocked sunlight, suppressed photosynthesis and drastically lowered worldwide temperatures. The resulting changes in temperature and available sunlight caused the dinosaurs and a host of other creatures to go extinct.

What do you think?
Does this constitute a valid scientific hypothesis? Why or Why Not?
Is it a likely explanation for dinosaurs extinction? Why or Why Not?

Best answer:

Answer by Craig H
Yeah, I think it constitutes a valid hypothesis. It explains it well because the lack of sunlight and heat caused the plants to die. The herbivores that eat those plants die following that. The carnivores who ate the herbivores had a lack of food and then hunted eachother, slowly depleting their populations, posibly resulting in cannibalism as well. They eventually over a few decades kill themselves extinct.

yeah, makes sense to me.
