Matt: I'm not conflating asteroid events with natural selection dhw, I'm stating that without a changed environment, there is NO evolution. The central point to "Natural Selection" is that changes we see in the fossil record happened by the challenge/response relationship between organisms and their environment.

> Refuting it, is simple: demonstrate speciation without a corresponding environmental change, and without human intervention.-Did environmental change cause multicellularity? Answer, we don't know. We can see that the most successful biomass on Earth are bacteria. Why bother with multicelualarity if so successful? And we still don't know how speciation is created, so your demonstration is wanting. Certain weird developments like mammals taking to water look like deliberate changes with n o obvious cause. My point is that we still do not know enough to know why we see evolutionary changes in form resulting from descrete jumps, not tiny increments. Most Darwin scientists seem to now recognize it is a major problem for the theory.
