Re: Lack of other impact-induced evidence

Hmm perhaps, visualisations helps.

Now, imagine the right side of the image is present day. As you can see, species B, C and D all share A as a common ancestor. Species A, B and C are extinct however. Now, you can say that species A turned into species B, and B turned into D, but what about C? That didn't turn into anything. That just went extinct.

This is what happens all the time in evolution.

Hope that helped.
