another of the so-called "Big Five," the extinction at the end of the
Triassic, also suggests that it was never a threat to ending animal life on
the planet. The K/T event seems unique. None of the other major extinctions appear to have been wholly or even partially caused by impacts."

"This is an excellent rebuttal to the nonsense spouted by BP, GB, and EG and supports what I said in my initial response (without having read the article) in far greater detail. I wish I had read the article first and just quoted these guys to avoid having to deal with several grossly erroneous"

I had assumed you had read the article. I just posted what I thought was interesting & might interest others in reading the article. Just because Ward spoke last does not mean he is right or that it's the last word on this topic. What Ward said I found interesting but hardly what I would consider conclusive or an "excellent rebuttal".
There is no reason to suspect that the K/T event was unique; I would describe it as the last large impact event. We know that the NEO population is not stable over millions of years (and is probably restocked), we know there are NEOs which are bigger than the rock that caused the K/T event. We know that impact event is "random". We know that larger rocks are rarer than smaller rocks & we are constantly being hit by smaller rocks with larger impactors as simply a more rare event. To think that the K/T event was the largest impactor in the last billion years defies logic- it's irrational.
