True. On the other hand, that doesn't change the fact that there's also
a vast, gaping hole in the impact theory as currently formulated.

The problem is that in every version of the impact theory I've ever
seen, the upper limit and lower limit cross. A ten-mile-diameter
planetoid is simply too large to have produced _only_ the effects that
we see in the fossil record. It should have done much, much more.
