New Evidence About 'The Great Dying' 250 Million Years Ago
PornMaster writes "The Guardian is reporting that scientists have found the first direct evidence that the killoff of 80% of land species and 95% of marine species 2 billion years ago was due to a meteor." The project web site has more info, maps, etc.
The usual explanation is that the remaining species can diversify into the ecological 'space' left after the holocaust.
In this view, in a crowded world, species are constantly in competition with each other, and diversity is held in balance, while in the time after a great extinction, all such constraints disappear, and species are free to do as they please.
Years ago, when Mariner 10 went and disovered the Caloris Basin and wierd terrain on Mercury, I immediately wondered if something like that could happen on Earth. I was one of the first to notice that the volcanic Deccan Traps that formed in India at the time of the dinosaur extinction just happened to be located (after taking contintental drift into account) on the opposite side of the Earth from Chixulub. (As I recall, I wrote a letter to Scientific American about it, way back then...but they didn't think it publishable) And now the evidence seems to be accumulating, in favor of exactly such scenarios.
What crap. Stop trolling. The evidence in science is based on pre-observed behaviour and hypothesis.
And they are just collecting evidence to substantiate their hypothesis.
Religious claims cannot be recreated. A scientific claim can.
Tomorrow if this is disproved, you can throw this out of the window. I'm yet to see any religious figurehead materialize before me -- that still hasn't made any religious believers throw out religion.
Science is based on assumptions, which evolve into hypothesis and are substantiated with evidence. Plain and simple. When another kind of evidence is found, science simply changes it's assumptions and hypothesis to fit the facts.
Besides, whether or not you believe it is entirely upto you. Your soul is not going to hell if you don't. It's just the most plausible thing that might have happened, and in the light of no other explanations, this seems just about right.
And look at the choice of words from the article -- they think, they believe etc. -- they do not say, we are so damn sure that THIS happened.
Have you been to the sun? How do you know it's full of Hydrogen and Helium? It's based on an assumption, that was later on substantiated with evidence (spectra of the sunlight). Have you seen a Black Hole? It was based on an assumption that it's quite likely Black hole exist, and later on they were substantiated with evidence by observation.
This is no different.
Religion merely makes claims, and has no need to substantiate nor prove. Unlike science.
And judging by your comments you know nothing of science.
