"Most of the species that did survive were highly resilient, and had the ability to remain dormant through the cosmic winter that followed. When conditions improved, these species had an advantage over their competitors and were able to proliferate and diversify." Hmmmmm. The problem with this theory seems to be that it provides no reason for why these forms weren't diversifying before the impact.
They don't really come out and say it, but it almost sounds like they're supporting Hoyle's theories about extraterrestrial origins for life on Earth.

It's just like how spacemen mated with apes to create the human race...it's happenning now!

Oh I struggle to be a true believing darwinite. Giant explosions lead to higher levels of complexity. This happens all the time in the real world. And if you don't see it, you must be a gullible 'creationist'!

There is a poster named Quix who is a big believer in the "Bible Codes" movement - people who think that the Hebrew Bible consists of hidden anagrams.
The main popularizer of this movement, Michael Drosnin, just followed up the original bestseller with a new book which suggests that he has found evidence of extraterrestrial origins for human life in his anagrams.
It's caused quite a stir in some circles.

I know who Quix is/was. I never paid enough attention to him to know about the ET angle....

The problem with this theory seems to be that it provides no reason for why these forms weren't diversifying before the impact. It's not that they weren't diversifying before the impact, it is that the existing forms were dominant under those pre-impact conditions and newly mutated forms really couldn't get a toe hold.
The impact both changed some conditions and wiped out a lot of the existing competition. And the race was on.

I thought it was going to play a pivotal role in the elimination of life? Make up my mind.

Make up my mind. Catastrophic events do end life and lots of it, but not all life. All critters that occupy an ecological niche may completely disappear with species higher up on the food chain being effected disproportionately.
So, as you can see, when conditions return to the new normal new species will evolve to replace those that went by the wayside.
The Dinosaurs ruled the Earth for over 100 million years then disappeared in the blink of an eon, to be replaced by the Mammals as top creature.

It's not that they weren't diversifying before the impact, it is that the existing forms were dominant under those pre-impact conditions and newly mutated forms really couldn't get a toe hold. That's not what the lady said. She said that after the ice age and before the impact, there were really simple things like algae and bacteria and stuff, and no evidence of diversification:
"As the sea level rose at the end of the ice age, these spherical forms increased in number," Dr Grey said. "But there is no sign of a new species emerging at the end of the intense ice age to support ideas of the rapid diversification of life at this time."
Only after this asteroid impact did all this new spiny stuff supposedly show up.
Now, both the ice age and the asteroid were associated with huge extinctions, but only the latter produced the rapid mutation. Given that the same beasties were supposedly around in each instance, we'd expect either to have seen mutations after the first extinction, too; or no mutations after the impact.
These researchers appear to be saying that it was something about the asteroid that made the difference -- hence my reference to Hoyle.

Actually,
birds kinda ran things for a short time after the demise of the dinosaurs.
