I think I'm missing something out as I'm pretty new to reading about Evolution in detail. I've watched a few programs and books and this is how its usually depicted:
Evolution started from Bacteria.
(tires a screeching, the bus comes to a sudden halt). Evolution is not about the origin of life.
Quote:Bacteria -> Fish -> Amphibians etc...
Asteroid happens killing the Dinosaurs.
Amphibians continue to Evolve.
All species evolve.
Quote:So my question is, if the Asteroid wiped out the Dinosaurs, wouldn't it of wiped out the Amphibians and everything else too?
Well, I'm a geologist, so here is what I think. I think that the asteroid impact theory is overused, and over-blown. I always have felt that way. Yes, an asteroid impacted the Earth. Yes, there were very dire consequences of the impact. The fact of the matter is that the dinosaurs were already in decline, and had been for at least 2 million years. No one can convince me that the Siberian trapps can wipe out some 90% of all life at the Permian-Triassic boundary, but the Deccan trapps can't do something similar at the KT boundary. And in fact, the Deccan trapps are responsible for the long term decline of many species before the impact occurred. Let's just say that the impact was merely the icing on the cake.
As for amphibians, the great thing about them is that they like it cool and damp, and with lots of insects eating off the offal, they likely had it pretty good.
Quote:I realise there are other theories such as Volcanos & Ice Aces but wouldn't this have the same effect too?
See above.
Quote:I know the majority of Scientists believe it was an Asteroid, but I just struggle to figure out how Evolution continued to happen if everything was wiped out?
Everything wasn't wiped out. It would take significantly more that a five mile diameter rock to sterilize the Earth.

"In short, Meyer has shown that his first disastrous book was not a fluke: he is capable of going into any field in which he has no training or research experience and botching it just as badly as he did molecular biology. As I've written before, if you are a complete amateur and don't understand a subject, don't demonstrate the Dunning-Kruger effect by writing a book about it and proving your ignorance to everyone else!
